syslog-ng - denial of service

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.

The old stable distribution (sarge) is not affected.

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

For the unstable distribution (sid), this problem has been fixed in
version 2.0.6-1.

We recommend that you upgrade your syslog-ng package.
