A Denial of Service vulnerability has been discovered in Syslog-ng.
Syslog-ng is a flexible and scalable system logger.
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:
