[原文]Floating point information leak in the context switch code for Linux 2.4.x only checks the MFH bit but does not verify the FPH owner, which allows local users to read register values of other processes by setting the MFH bit.


[CNNVD]Linux Kernel浮点寄存器内容泄露漏洞(CNNVD-200412-044)

        
        Linux是一款开放源代码操作系统。
        Linux内核浮点寄存器存在问题,本地攻击者可以利用这个漏洞获得其他进程的敏感信息。
        Linux 2.4.x和SLES9/ia64内核存在浮点泄露问题,原因是内容交换代码只检查psr.mfh位和没有查看FPH的属主。这允许恶意程序设置MFH位并查看其他敏感进程中寄存器信息。

     The ELF loader is vulnerable to denial of service through malformed
     binaries.

 CVE-2005-0003

     Crafted ELF binaries may lead to privilege escalation, due to 
     insufficient checking of overlapping memory regions.

 CVE-2004-1235

     A race condition in the load_elf_library() and binfmt_aout() functions
     may allow privilege escalation.

 CVE-2005-0504

     An integer overflow in the Moxa driver may lead to privilege escalation.

 CVE-2005-0384

     A remote denial of service vulnerability has been found in the PPP
     driver.

 CVE-2005-0135

     An IA64 specific local denial of service vulnerability has been found
     in the unw_unwind_to_user() function.

The following matrix explains which kernel version for which architecture
fix the problems mentioned above:

                                     Debian 3.0 (woody)
     Source                          2.4.19-4
     Sun Sparc architecture          26woody1
     Little endian MIPS architecture 0.020911.1.woody5


We recommend that you upgrade your kernel package immediately and reboot
the machine.

Upgrade Instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get dist-upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.

CVE-2004-0565
[点击下载]

Arun Sharma has discovered a vulnerability that affects Linux ia64 kernels. When the psr.mfh bit is checked without checking the identity of the FPH owner, another process may be able to see the first process's registers.

Opened by  (Arun Sharma) on 2004-05-28 17:46

Description of problem:

Linux 2.4.x and the SLES9/ia64 kernels have a floating point leak.
This is because the context switch code checks just the psr.mfh bit
and doesn't look at who the FPH owner is.

This allows a malicious program to set the MFH bit and look at the
registers of another possibly sensitive process.

Version-Release number of selected component (if applicable):

2.4.21-12.EL.

How reproducible:

Run N (= number of cpus) copies of the program secret and one copy of
the program check.

Linux Kernel MFH Bit Information Disclosure
Local Access Required Information Disclosure, Other
Loss of Confidentiality
Exploit Public

- 漏洞描述

The ia64 Linux Kernel contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered when a floating point leak occurs, which will disclose the registers of other process information resulting in a loss of confidentiality.
