Debian Security Advisory DSA-1464-1 security@debian.org
http://www.debian.org/security/ Moritz Muehlenhoff
January 15, 2008 http://www.debian.org/security/faq
- - ------------------------------------------------------------------------
Package : syslog-ng
Vulnerability : null pointer dereference
Problem type : local
Debian-specific: no
CVE Id(s) : CVE-2007-6437
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.
For the unstable distribution (sid), this problem has been fixed in
version 2.0.6-1.
For the stable distribution (etch), this problem has been fixed in
version 2.0.0-1etch1.
The old stable distribution (sarge) is not affected.
We recommend that you upgrade your syslog-ng package.
