The GNU C library is the standard C library used by Gentoo Linux systems.
Multiple vulnerabilities have been discovered in GNU C Library. Please review the CVE identifiers referenced below for details.
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.
There is no known workaround at this time.
All GNU C Library users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-libs/glibc-2.15-r3"
