GNU C library: Multiple vulnerabilities — GLSA 201011-01

Multiple vulnerabilities were found in glibc, the worst of which allowing local attackers to execute arbitrary code as root.

Affected Packages

sys-libs/glibc on all architectures
Affected versions < 2.11.2-r3
Unaffected versions >= 2.11.2-r3

Background

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

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"
