Syslog-ng: Chroot escape

Syslog-ng: Chroot escape Syslog-ng does not properly initialize its chroot jail allowing for an escape if a separate vulnerability in Syslog-ng is exploited. syslog-ng 2009-07-12 2009-07-12 247278 local 2.0.10 2.1.3 2.1.3

Syslog-ng is a flexible and scalable system logger.

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

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

There is no known workaround at this time.

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"
