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