  <title>Syslog-ng: Chroot escape</title>
  <synopsis>
    Syslog-ng does not properly initialize its chroot jail allowing for an
    escape if a separate vulnerability in Syslog-ng is exploited.

    <p>
    Syslog-ng is a flexible and scalable system logger.

  <description>
    <p>
    Florian Grandel reported that Syslog-ng does not call chdir() before
    chroot() which leads to an inherited file descriptor to the current
    working directory.
    </p>
  </description>
  <impact type="low">
    <p>
    A local attacker might exploit a separate vulnerability in Syslog-ng
    and use this vulnerability to escape the chroot jail.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Syslog-ng 2.0 users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-admin/syslog-ng-2.0.10"</code>
    <p>
    All Syslog-ng 2.1 users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-admin/syslog-ng-2.1.3"</code>
