Debian DSA-1464-1 : syslog-ng - NULL pointer dereference

medium Nessus Plugin ID 29984

Synopsis

The remote Debian host is missing a security-related update.

Description

Oriol Carreras discovered that syslog-ng, a next generation logging daemon can be tricked into dereferencing a NULL pointer through malformed timestamps, which can lead to denial of service and the disguise of an subsequent attack, which would otherwise be logged.

Solution

Upgrade the syslog-ng package.

The old stable distribution (sarge) is not affected.

For the stable distribution (etch), this problem has been fixed in version 2.0.0-1etch1.
