  <title>Linux-PAM: Multiple vulnerabilities</title>
  <synopsis>Multiple vulnerabilities have been found in Linux-PAM, allowing
    local attackers to possibly gain escalated privileges, cause a Denial of
    Service, corrupt data, or obtain sensitive information.

  <background>
    <p>Linux-PAM (Pluggable Authentication Modules) is an architecture allowing
      the separation of the development of privilege granting software from the
      development of secure and appropriate authentication schemes.
    </p>
  </background>
  <description>
    <p>Multiple vulnerabilities have been discovered in Linux-PAM. Please
      review the CVE identifiers referenced below for details.
    </p>
  </description>
  <impact type="high">
    <p>A local attacker could use specially crafted files to cause a buffer
      overflow, possibly resulting in privilege escalation or Denial of
      Service. Furthermore, a local attacker could execute specially crafted
      programs or symlink attacks, possibly resulting in data loss or
      disclosure of sensitive information.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All Linux-PAM users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=sys-libs/pam-1.1.5"
    </code>
    
    <p>NOTE: This is a legacy GLSA. Updates for all affected architectures are
      available since November 25, 2011. It is likely that your system is
      already no longer affected by this issue.
