Description Lubomir Kundrak 2007-12-18 23:11:55 UTC

From Secunia:

DESCRIPTION:
A vulnerability has been reported in syslog-ng, which can be
exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to the improper processing of
incoming timestamps. This can be exploited to trigger a NULL pointer
dereference via a specially crafted message containing a timestamp
without a terminating space character.

The vulnerability is reported in syslog-ng versions prior to 2.0.6

See URL for the original advisory and a patch.
