|Gentoo Linux Security Advisory
Title: Syslog-ng: Denial of Service (GLSA 200712-19)
Date: December 29, 2007
A Denial of Service vulnerability has been discovered in Syslog-ng.
Syslog-ng is a flexible and scalable system logger.
Vulnerable: < 2.0.6
Unaffected: >= 2.0.6
Architectures: All supported architectures
Oriol Carreras reported a NULL pointer dereference in the log_msg_parse() function when processing timestamps without a terminating whitespace character.
A remote attacker could send a specially crafted event to a vulnerable Syslog-ng server, resulting in a crash.
There is no known workaround at this time.
All Syslog-ng users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=app-admin/syslog-ng-2.0.6"
