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 ">=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. </p> </resolution> <references> <uri link="https://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-3316">CVE-2010-3316</uri> <uri link="https://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-3430">CVE-2010-3430</uri> <uri link="https://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-3431">CVE-2010-3431</uri> <uri link="https://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-3435">CVE-2010-3435</uri> <uri link="https://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-3853">CVE-2010-3853</uri> <uri link="https://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-4706">CVE-2010-4706</uri> <uri link="https://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-4707">CVE-2010-4707</uri> <uri link="https://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-4708">CVE-2010-4708</uri> <uri link="https://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-3148">CVE-2011-3148</uri> <uri link="https://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-3149">CVE-2011-3149</uri> </references> <metadata timestamp="2011-10-07T23:37:20Z" tag="requester"> underling </metadata> <metadata timestamp="2012-06-25T18:51:25Z" tag="submitter">craig</metadata> </glsa>
