Gentoo Linux Security Advisory

Title: GNU C library: Multiple vulnerabilities (GLSA 201011-01)
Severity: high
Exploitable: local remote
Date: November 15, 2010
Bug(s): #285818, #325555, #330923, #335871, #341755
ID: 201011-01

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: sys-libs/glibc
Vulnerable: < 2.11.2-r3
Unaffected: >= 2.11.2-r3
Architectures: All supported architectures


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:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=sys-libs/glibc-2.11.2-r3"
