[原文]Multiple TCP/IP and ICMP implementations, when using Path MTU (PMTU) discovery (PMTUD), allow remote attackers to cause a denial of service (network throughput reduction for TCP connections) via forged ICMP ("Fragmentation Needed and Don't Fragment was Set") packets with a low next-hop MTU value, aka the "Path MTU discovery attack." NOTE: CVE-2004-0790, CVE-2004-0791, and CVE-2004-1060 have been SPLIT based on different attacks; CVE-2005-0065, CVE-2005-0066, CVE-2005-0067, and CVE-2005-0068 are related identifiers that are SPLIT based on the underlying vulnerability. While CVE normally SPLITs based on vulnerability, the attack-based identifiers exist due to the variety and number of affected implementations and solutions that address the attacks instead of the underlying vulnerabilities.

SUPPORTED SOFTWARE VERSIONS*:  ONLY impacted versions are listed.
HP-UX B.11.00, B.11.04, B.11.11, B.11.22, B.11.23 running TCP/IP.
HP-UX B.11.11 and B.11.23 running TOUR (Transport Optional Upgrade
Release).

BACKGROUND:

     AFFECTED VERSIONS

     HP-UX B.11.22
     HP-UX B.11.00
     =============
     Networking.NET2-KRN
     action: set ip_pmtu_strategy= 0 and either install binary
             files or filter ICMP

     HP-UX B.11.11
     =============
     Networking.NET2-KRN
     action: set ip_pmtu_strategy= 0 and install PHNE_33159

     HP-UX B.11.23
     =============
     Networking.NET2-KRN
 ->action: set ip_pmtu_strategy= 0 and install PHNE_32606

     HP-UX B.11.11
     HP-UX B.11.23
     =============
     TOUR_PRODUCT.T-NET2-KRN
     action: set ip_pmtu_strategy= 0 and filter ICMP


     HP-UX B.11.04
     =============
     Networking.NET2-KRN
     action: set ip_pmtu_strategy= 0 and filter ICMP

     END AFFECTED VERSIONS


 Note: The latest TOUR (Transport Optional Upgrade Release),
       version 2.4, is available on B.11.11 only.  The latest
       Transport Functionality is available to B.11.23 customers
       in the HP-UX 11i v2 September 2004 release.   Customers
       using TOUR on B.11.23 can apply the workaround (set
       ip_pmtu_strategy= 0 and filter ICMP) or upgrade to the
       HP-UX 11i v2 September 2004 release.  After upgrading the
       action for B.11.23 Networking.NET2-KRN listed above should
       be implemented.

RESOLUTION:

As reported in NISCC VU#532967 ICMP messages may be used to attack
TCP/IP connections.

<http://www.uniras.gov.uk/niscc/docs/al-20050412-00308.html?
lang=en>

There are three issues reported in NISCC VU#532967:

  CVE number: CAN-2004-0790
 <http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0790>
  CVE number: CAN-2004-0791
 <http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0791>
  CVE number: CAN-2004-1060
 <http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-1060>

Workarounds are available for all three of these issues.

Until binary files are available for B.11.04 the workarounds
should be used.


 ->Binary files are available for CAN-2004-0790 and CAN-2004-0791
for HP-UX  B.11.00 and B.11.22.

Since PHNE_33159 is now available for B.11.11 the preliminary
binary  files for B.11.11 have been removed from the ftp site.

 ->Since PHNE_32606 is now available for B.11.23 the preliminary
binary  files for B.11.23 have been removed from the ftp site.


Note: If the TOUR (Transport Optional Upgrade Release) product is
      installed the binary files cannot be used.

Until the TOUR product is revised there are several options:

 B.11.11
    1. Use the workarounds.
       or
   2. Remove TOUR and install the binary files.

 B.11.23
    1. Use the workarounds.
        or
   2. Upgrade to the HP-UX 11i v2 September 2004 release
       and install the binary files.

TOUR(Transport Optional Upgrade Release) is available from
<http://www.hp.com/go/softwaredepot>.


Workaround for CAN-2004-1060 may not be necessary.
===================================
Although changes in the binary files and patches for CAN-2004-0790
and CAN-2004-0791 do not prevent the exploit of CAN-2004-1060,
they do make it less likely to succeed.  The sequence number check
suggested in section 5.1 of <http://www.ietf.org/internet-drafts/
draft-gont-tcpm-icmp-attacks-03.txt> has been implemented.
Customers should consider whether this check reduces the risk of
the exploit to the point that setting ip_pmtu_strategy=0 is not
required.

If the workaround for CAN-2004-1060 is to be used, please note
the following:
=================================================
HPSBUX01137 recommends setting ip_pmtu_strategy = 0 or 3 as a
workaround for the problem of CAN-2005-1192.   CAN-2004-1060 has a
different root cause and cannot be worked around with
p_pmtu_strategy=3.   To work around both CAN-2005-1192 and
CAN-2004-1060 ip_pmtu_strategy=0 must be used.

Please refer to the Manual Actions section below for a summary of
the required actions.

Workarounds:

  CAN-2004-0790 and CAN-2004-0791

     Filter out the following ICMP messages:

    Type 3, Code 2 (Destination Unreachable, Protocol Unreachable)
    Type 3, Code 3 (Destination Unreachable, Port Unreachable)
    Type 4, Code 0 (Source Quench)

  CAN-2004-1060

     Set ip_pmtu_strategy=0.

Note: Filtering "Protocol Unreachable" and "Port Unreachable"
      should not be done without careful testing.  Filtering these
      out may interfere with the correct functioning of network
      components.
      Filtering "Source Quench" should present little risk.


Setting ip_pmtu_strategy=0
==================
Edit /etc/rc.config.d/nddconf to add the following:

TRANSPORT_NAME[n]=ip
NDD_NAME[n]=ip_pmtu_strategy
NDD_VALUE[n]=0

where 'n' is the next available index value as described in the
nddconf comments.

This value will take effect when the system is rebooted.
Until the system can be rebooted use the following command
to read the /etc/rc.config.d/nddconf file and set the tunable
parameters:

  /usr/bin/ndd -c

The ip_pmtu_strategy parameter can be displayed by the
following command:

  /usr/bin/ndd -get /dev/ip ip_pmtu_strategy

Note: Since open connections will remain potentially vulnerable
      until they are closed and certain internal data structures
      are released it is recommended that the system be rebooted.

Note: There is a defect that will cause "ndd -c" to fail if there
      are more than 10 directives in /etc/rc.config.d/nddconf.
      That defect is fixed in the following patches:

              B.11.11 - PHNE_25644 or subsequent
              B.11.04 - PHNE_26076 or subsequent
              B.11.00 - PHNE_26125 or subsequent


Preliminary binary files
==============

 ->Preliminary binary files are available for B.11.00 and B.11.22.
Patches are available for B.11.11 and B.11.23.  The patches and
the preliminary binary files address CAN-2004-0790 and
CAN-2004-0791 only.  Although changes in the patches and binary
files for CAN-2004-0790 and CAN-2004-0791 do not prevent the
exploit of CAN-2004-1060, they do make it less likely to succeed.

Instructions for downloading and installing the binary files are
contained in readme files available here:

     System:    hprc.external.hp.com  (192.170.19.51)
     Login:     icmp

    Note: The links above may not work for all browsers.  If the
          link fails the url should be entered directly into the
          browser's address field.

Since a patch is available for B.11.11 the readme.11.11.txt and
corresponding binary files have been removed from the ftp site.

BACKGROUND:

Special Instructions for the Customer

The Internet Control Message Protocol (ICMP) (RFC 792) is used in
the Internet Architecture to perform fault-isolation and recovery
(RFC816), which is the group of actions that hosts and routers
take to determine if a network failure has occurred.

The industry standard TCP specification (RFC 793) has a
vulnerability whereby ICMP packets can be used to perform a
variety of attacks such as blind connection reset attacks and
blind throughput-reduction attacks. Blind connection reset
attacks can be triggered by an attacker sending forged ICMP
"Destination Unreachable, host unreachable" packets or ICMP
"Destination Unreachable, port unreachable" packets.  Blind
throughput-reduction attacks can be caused by an attacker sending
a forged ICMP type 4 (Source Quench) packet.

Path MTU Discovery (RFC 1191) describes a technique for
dynamically discovering the MTU (maximum transmission unit) of an
arbitrary internet path.  This protocol uses ICMP packets from
the router to discover the MTU for a TCP connection path.  An
attacker can reduce the throughput of a TCP connection by sending
forged ICMP packets (or their IPv6 counterpart) to the
discovering host, causing an incorrect Path MTU setting.

HP has addressed these potential vulnerabilities by providing a
new kernel tunable in Tru64 UNIX V5.1B and 5.1A,
icmp_tcpseqcheck. In Tru64 4.0F and 4.0G, HP has introduced two
new kernel tunables, icmp_tcpseqcheck and icmp_rejectcodemask.
The icmp_rejectcodemask tunable is already available in Tru64
UNIX V5.1B and 5.1A.

icmp_tcpseqcheck

The icmp_tcpseqcheck variable mitigates ICMP attacks against TCP
by checking that the TCP sequence number contained in the payload
of the ICMP error message is within the range of the data already
sent but not yet acknowledged. An ICMP error message that does
not pass this check is discarded. This behavior protects TCP
against spoofed ICMP packets.

Set the tunable as follows:

  icmp_tcpseqcheck=1 (default)

    Provides a level of protection that reduces the possibility
    of considering a spoofed ICMP packet as valid
    to one in two raised to the thirty-second power.

  icmp_tcpseqcheck=0

    Retains existing behavior, i.e., accepts all ICMP packets

icmp_rejectcodemask

In the Requirements for IP Version 4 Routers (RFC 1812), research
suggests that the use of ICMP Source Quench packets is an
ineffective (and unfair) antidote for congestion. Thus, HP
recommends completely ignoring ICMP Source Quench packets using
the icmp_rejectcodemask tunable. The icmp_rejectcodemask is a
bitmask that designates the ICMP codes that the system should
reject. For example, to reject ICMP Source Quench packets,
set the mask bit position for the ICMP_SOURCEQUENCH code 4,
which is two to the 4th power = 16 (0x10 hex).
The icmp_rejectcodemask tunable can be used to reject any
ICMP packet type, or multiple masks can be combined to reject
more than one type.

Note: the ICMP type codes are defined in
      "/usr/include/netinet/ip_icmp.h".

  Set the tunable as follows:

    icmp_rejectcodemask = 0x10

      Rejects ICMP Source Quench packets

    icmp_rejectcodemask = 0 (default)

      Retains existing behavior, i.e., accepts all ICMP packets

Adjusting the variables

The ICMP sequence check variable (icmp_tcpseqcheck) can be
adjusted using the sysconfig and sysconfigdb commands:

# sysconfig -q inet icmp_tcpseqcheck
inet:
icmp_tcpseqcheck = 1
# sysconfig -r inet icmp_tcpseqcheck=0
icmp_tcpseqcheck: reconfigured
# sysconfig -q inet icmp_tcpseqcheck
inet:
icmp_tcpseqcheck = 0
# sysconfig -q inet icmp_tcpseqcheck > /tmp/icmp_tcpseqcheck_merge
# sysconfigdb -m -f /tmp/icmp_tcpseqcheck_merge inet
# sysconfigdb -l inet

inet:
      icmp_tcpseqcheck = 1

Similarly, the icmp_rejectcodemask variable can be adjusted using
the sysconfig and sysconfigdb commands:

# sysconfig -q inet icmp_rejectcodemask
inet:
icmp_rejectcodemask = 0
# sysconfig -r inet icmp_rejectcodemask=0x10
icmp_rejectcodemask: reconfigured
# sysconfig -q inet icmp_rejectcodemask
inet:
icmp_rejectcodemask = 16
# sysconfig -q inet icmp_rejectcodemask
   > /tmp/icmp_rejectcodemask_merge
# sysconfigdb -m -f /tmp/icmp_rejectcodemask_merge inet
# sysconfigdb -l inet

inet:
        icmp_rejectcodemask = 16

RESOLUTION:

Until the corrections are available in a mainstream
release patch kit, HP is releasing the following Early Release
Patch (ERP) kits publicly for use by any customer.

The ERP kits use dupatch to install and will not install over
any installed Customer Specific Patches (CSPs) that have file
intersections with the ERPs. Contact your service provider for
assistance if the ERP installation is blocked by any of your
installed CSPs.

The fixes contained in the ERP kits are scheduled to be
available in the following mainstream patch kits:

- 漏洞讨论

Multiple vendor implementations of TCP/IP Internet Control Message Protocol (ICMP) are reported prone to several denial-of-service attacks.

ICMP is employed by network nodes to determine certain automatic actions to take based on network failures reported by an ICMP message.

Reportedly, the RFC doesn't recommend security checks for ICMP error messages. As long as an ICMP message contains a valid source and destination IP address and port pair, it will be accepted for an associated connection.

The following individual attacks are reported:

- A blind connection-reset attack. This attack takes advantage of the specification that describes that on receiving a 'hard' ICMP error, the corresponding connection should be aborted. The Mitre ID CAN-2004-0790 is assigned to this issue.

A remote attacker may exploit this issue to terminate target TCP connections and deny service for legitimate users.

- An ICMP Source Quench attack. This attack takes advantage of the specification that a host must react to receive ICMP Source Quench messages by slowing transmission on the associated connection. The Mitre ID CAN-2004-0791 is assigned to this issue.

A remote attacker may exploit this issue to degrade the performance of TCP connections and partially deny service for legitimate users.

- An attack against ICMP PMTUD is reported to affect multiple vendors when they are configured to employ PMTUD. By sending a suitable forged ICMP message to a target host, an attacker may reduce the MTU for a given connection. The Mitre ID CAN-2004-1060 is assigned to this issue.

A remote attacker may exploit this issue to degrade the performance of TCP connections and partially deny service for legitimate users.

**Update: Microsoft platforms are also reported prone to these issues.
