[原文]The auto-reap of child processes in Linux kernel 2.6 before 2.6.15 includes processes with ptrace attached, which leads to a dangling ptrace reference and allows local users to cause a denial of service (crash) and gain root privileges.


[CNNVD]Linux Kernel auto-reap ptraced子进程本地拒绝服务漏洞(CNNVD-200511-360)

        Linux Kernel是开放源码操作系统Linux所使用的内核。
        Linux Kernel对系统进程的处理上存在问题,本地攻击者可能利用此漏洞进行拒绝服务攻击。漏洞存在于signal.c文件中,内核对子进程执行auto-reap操作时,操作对象包含了已经被ptrace附着的进程,这可能导致ptrace引用混乱,允许本地攻击者触发拒绝服务问题。

 Package : kernel
 Date    : July 5, 2006
 Affected: Corporate 3.0, Multi Network Firewall 2.0
 _______________________________________________________________________
 
 Problem Description:
 
 A number of vulnerabilities were discovered and corrected in the Linux
 2.6 kernel:
 
 Prior to 2.6.14, the atm module allows local users to cause a Denial of
 Service (panic) via certain socket calls that produce inconsistent
 reference counts for loadable protocol modules (CVE-2005-3359).
 
 Prior to 2.6.15, the auto-reap child processes included processes with
 ptrace attached, leading to a dangling ptrace reference and allowing
 local users to cause a Denial of Service (crash) (CVE-2005-3784).
 
 Prior to and including 2.6.12, a memory leak in the ip6_input_finish
 function could allow an attacker to cause a Denial of Service via
 malformed IPv6 packets with unspecified parameter problems, which
 prevents SKB from being freed (CVE-2005-3858).
 
 Prior to 2.6.15, a buffer overflow in sysctl could allow a local user
 to corrupt user memory and possibly cause a Denial of Service via a
 long string, causing sysctl to write a zero byte outside the buffer
 (CVE-2005-4618).
 
 Prior to 2.6.11, wan/sdla.c does not require CAP_SYS_RAWIO privilege
 for an SDLA firmware upgrade, with unknown impact and local attack
 vectors (CVE-2006-0096).
 
 Prior to 2.6.15.5, a local user could cause a Denial of Service (NFS
 client panic) via unknown attack vectors related to the use of O_DIRECT
 (direct I/O) (CVE-2006-0555).
 
 Prior to 2.6.16, the ip_push_pending_frames function increments the IP
 ID field when sending a RST after receiving unsolicited TCP SYN-ACK
 packets, which allows a remote attacker to conduct an idle scan attack,
 bypassing any intended protection against such an attack
 (CVE-2006-1242).
 
 Prior to 2.6.16.8, the ip_route_input function allows local users to
 cause a DoS (panic) via a request for a route for a multicast IP
 address, which triggers a null dereference (CVE-2006-1525).
 
 Prior to 2.6.13, local users could cause a Denial of Service (crash)
 via a dio transfer from the sg driver to memory mapped IO space
 (CVE-2006-1528).
 
 Prior to 2.6.11.12, the choose_new_parent function includes certain
 debugging code which could allow a local user to cause a Denial of
 Service (panic) by causing certain circumstances involving termination
 of a parent process (CVE-2006-1855).
 
 Prior to and including 2.6.16, the kernel did not add the appropriate
 LSM file_permission hooks to the readv and writev functions, which
 could allow an attacker to bypass intended access restrictions
 (CVE-2006-1856).
 
 Prior to 2.6.16, local users can bypass IPC permissions and modify a
 read-only attachment of shared memory by using mprotect to give write
 permission to the attachment (CVE-2006-2071).
 
 Prior to 2.6.17, the ECNE chunk handling in SCTP (lksctp) allows remote
 attackers to cause a DoS (kernel panic) via an unexpected chucnk when
 the session is in CLOSED state (CVE-2006-2271).
 
 Prior to 2.6.17, SCTP (lksctp) allows remote attacker to cause a DoS
 (kernel panic) via incoming IP fragmented COOKIE_ECHO and HEARTBEAT
 SCTP control chunks (CVE-2006-2272).
 
 Memory corruption can be triggered remotely when the ip_nat_snmp_basic
 module is loaded and traffic on port 161 or 162 is NATed
 (CVE-2006-2444).
 
 The provided packages are patched to fix these vulnerabilities.  All
 users are encouraged to upgrade to these updated kernels.

Trustix Secure Linux Security Advisory #2005-0070

Package names:	   kernel, perl
Summary:           Multiple vulnerabilities
Date:              2005-12-09
Affected versions: Trustix Secure Linux 2.2
                   Trustix Secure Linux 3.0
                   Trustix Operating System - Enterprise Server 2

- --------------------------------------------------------------------------
Package description:
  kernel
  The kernel package contains the Linux kernel (vmlinuz), the core of your
  Trustix Secure Linux operating system.  The kernel handles the basic
  functions of the operating system:  memory allocation, process 
  allocation, device input and output, etc.

  perl
  Perl is a high-level programming language with roots in C, sed, awk and
  shell scripting. Perl is good at handling processes and files, and is 
  especially good at handling text. Perl's hallmarks are practicality and
  efficiency. While it is used to do a lot of different things, Perl's 
  most common applications (and what it excels at) are probably system
  administration utilities and web programming. A large proportion of the
  CGI scripts on the web are written in Perl. You need the perl package 
  installed on your system so that your system can handle Perl scripts.

Problem description:
  kernel < TSL 3.0 >
  - New Upstream.
  - SECURITY Fix: Memory leak in the VFS file lease handling in locks.c
    allows local users to cause a denial of service via certain Samba
    activities that cause an fasync entry to be re-allocated by the
    fcntl_setlease function after the fasync queue has already been 
    cleaned by the locks_delete_lock function.
  - The auto-reap of child processes in Linux kernel 2.6 includes 
    processes with ptrace attached, which leads to a dangling ptrace 
    reference and allows local users to cause a denial of service (crash).
  - The time_out_leases function in locks.c allows local users to cause a
    denial of service (kernel log message consumption) by causing a large
    number of broken leases, which is recorded to the log using the printk
    function.

    The Common Vulnerabilities and Exposures project (cve.mitre.org) has
    assigned the names CVE-2005-3807, CVE-2005-3784 and CVE-2005-3857 to
    these issues.
  
  perl < TSL 3.0 > < TSL 2.2 > < TSEL 2 >
  - SECURITY Fix: Integer overflow in the format string functionality
    (Perl_sv_vcatpvfn) allows attackers to overwrite arbitrary memory and
    possibly execute arbitrary code via format string specifiers with

- 漏洞讨论

Linux kernel is prone to a local denial-of-service vulnerability. The kernel improperly auto-reaps processes when they are being ptraced, leading to an invalid pointer. Further operations on this pointer result in a kernel crash.

This issue allows local users to crash the kernel, denying service to legitimate users.

A complete compromise of the affected computer has also been reported, but this has not been confirmed.

Kernel versions prior to 2.6.15 are vulnerable to this issue.

- 漏洞利用

Currently we are not aware of any exploits for this issue. If you feel we are in error or if you are aware of more recent information, please mail us at: vuldb@securityfocus.com

- 解决方案

Please see the referenced vendor advisories for information on obtaining and applying the appropriate updates.

Linux kernel versions 2.6.15-rc3 and 2.6.14.3 have been released to address this issue.
