Synopsis
=======
Syslog-ng does not properly initialize its chroot jail allowing for an
escape if a separate vulnerability in Syslog-ng is exploited.

Background
=========
Syslog-ng is a flexible and scalable system logger.

Affected packages
================
    -------------------------------------------------------------------
     Package              /  Vulnerable  /                  Unaffected
    -------------------------------------------------------------------
  1  app-admin/syslog-ng       < 2.1.3                      *>= 2.0.10
                                                              >= 2.1.3

Description
==========
Florian Grandel reported that Syslog-ng does not call chdir() before
chroot() which leads to an inherited file descriptor to the current
working directory.

Impact
=====
A local attacker might exploit a separate vulnerability in Syslog-ng
and use this vulnerability to escape the chroot jail.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All Syslog-ng 2.0 users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-admin/syslog-ng-2.0.10"

All Syslog-ng 2.1 users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-admin/syslog-ng-2.1.3"
