Synopsis
========
Multiple vulnerabilities were found in glibc, the worst of which
allowing local attackers to execute arbitrary code as root.
Background
==========
The GNU C library is the standard C library used by Gentoo Linux
systems.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-libs/glibc < 2.11.2-r3 >= 2.11.2-r3
Description
===========
Multiple vulnerabilities were found in glibc, amongst others the
widely-known recent LD_AUDIT and $ORIGIN issues. For further
information please consult the CVE entries referenced below.
Impact
======
A local attacker could execute arbitrary code as root, cause a Denial
of Service, or gain privileges. Additionally, a user-assisted remote
attacker could cause the execution of arbitrary code, and a
context-dependent attacker could cause 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-2.11.2-r3"
