<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.
