Title
=====

Two Mandriva Linux Security Advisories:

1. MDKSA-2007:001 - Update libmodplug packages fix buffer overflow vulnerabilities

2. MDKSA-2007:002 - Updated kernel packages fix multiple vulnerabilities and bugs

Detail
======

1. Multiple buffer overflows in MODPlug Tracker (OpenMPT) 1.17.02.43 and earlier and libmodplug 0.8 and earlier allow user-assisted remote attackers to execute arbitrary code via (1) long strings in ITP files used by the CSoundFile::ReadITProject function in soundlib/Load_it.cpp and (2) crafted modules used by the CSoundFile::ReadSample function in soundlib/Sndfile.cpp, as demonstrated by crafted AMF files.

2. Some vulnerabilities were discovered and corrected in the Linux 2.6 kernel.

Problem Description:

Multiple buffer overflows in MODPlug Tracker (OpenMPT) 1.17.02.43 and earlier and libmodplug 0.8 and earlier allow user-assisted remote attackers to execute arbitrary code via (1) long strings in ITP files used by the CSoundFile::ReadITProject function in soundlib/Load_it.cpp and (2) crafted modules used by the CSoundFile::ReadSample function in soundlib/Sndfile.cpp, as demonstrated by crafted AMF files.

Updated packages are patched to address this issue.

Mandriva Linux Security Advisory MDKSA-2007:002
http://www.mandriva.com/security/
_______________________________________________________________________

Package : kernel
Date : January 2, 2007
Affected: 2007.0
_______________________________________________________________________

Problem Description:

Some vulnerabilities were discovered and corrected in the Linux 2.6
kernel:

The Linux kernel does not properly save or restore EFLAGS during a context switch, or reset the flags when creating new threads, which could allow a local user to cause a Denial of Service (process crash) (CVE-2006-5173).

The seqfile handling in the 2.6 kernel up to 2.6.18 allows local users to cause a DoS (hang or oops) via unspecified manipulations that trigger an infinite loop while searching for flowlabels (CVE-2006-5619).

An integer overflow in the 2.6 kernel prior to 2.6.18.4 could allow a local user to execute arbitrary code via a large maxnum value in an ioctl request (CVE-2006-5751).

A race condition in the ISO9660 filesystem handling could allow a local user to cause a DoS (infinite loop) by mounting a crafted ISO9660 filesystem containing malformed data structures (CVE-2006-5757).

A vulnerability in the bluetooth support could allow for overwriting internal CMTP and CAPI data structures via malformed packets (CVE-2006-6106).

The provided packages are patched to fix these vulnerabilities. All users are encouraged to upgrade to these updated kernels immediately and reboot to effect the fixes.

In addition to these security fixes, other fixes have been included such as:

- added the marvell IDE driver - use a specific driver Jmicron chipsets rather than using a generic one - updated the sky2 driver to fix some network hang issues

To update your kernel, please follow the directions located at:
