Detail
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. 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" References [ 1 ] CVE-2009-4880 : http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-4880 [ 2 ] CVE-2009-4881 : http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-4881 [ 3 ] CVE-2010-0296 : http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-0296 [ 4 ] CVE-2010-0830 : http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-0830 [ 5 ] CVE-2010-3847 : http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-3847 [ 6 ] CVE-2010-3856 : http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-3856 Availability This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201011-01.xml |
