Synopsis
========
Multiple vulnerabilities have been found in GNU C Library, the worst of
which allowing arbitrary code execution and privilege escalation.

Background
==========
The GNU C library is the standard C library used by Gentoo Linux
systems.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-libs/glibc < 2.15-r3 >= 2.15-r3

Description
===========
Multiple vulnerabilities have been discovered in GNU C Library. Please
review the CVE identifiers referenced below for details.

Impact
======
A local attacker could trigger vulnerabilities in dynamic library
loader, making it possible to load attacker-controlled shared objects
during execution of setuid/setgid programs to escalate privileges.

A context-dependent attacker could trigger various vulnerabilities in
GNU C Library, including a buffer overflow, leading to execution of
arbitrary code or a Denial of Service.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All GNU C Library users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-libs/glibc-2.15-r3"
