openSUSE Security Update: glibc: Security update to fix security problems
______________________________________________________________________________

Announcement ID: openSUSE-SU-2010:0912-1
Rating: important
References: #572188 #646960
Cross-References: CVE-2010-3847 CVE-2010-3856
Affected Products:
openSUSE 11.3
______________________________________________________________________________

An update that fixes two vulnerabilities is now available.

Description:

This update of glibc fixes two bugs and security issues:

CVE-2010-3847: Decoding of the $ORIGIN special value in
various LD_ environment variables allowed local attackers
to execute code in context of e.g. setuid root programs,
elevating privileges. This issue does not affect SUSE as
an assertion triggers before the respective code is
executed. The bug was fixed nevertheless.

CVE-2010-3856: The LD_AUDIT environment was not pruned
during setuid root execution and could load shared
libraries from standard system library paths. This could be
used by local attackers to inject code into setuid root
programs and so elevated privileges.


Patch Instructions:

To install this openSUSE Security Update use YaST online_update.
Alternatively you can run the command listed for your product:

- openSUSE 11.3:

zypper in -t patch glibc-3401
