  <background>
    <p>The GNU C library is the standard C library used by Gentoo Linux
      systems.
    </p>

  <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>
