DSA 175-1-New syslog-ng packages fix buffer overflow

by Nikola Strahija on October 16th, 2002 Péter Höltzl discovered a problem in the way syslog-ng handles macro expansion. When a macro is expanded a static length buffer is used accompanied by a counter. However, when constant chharacters are appended, the counter is not updated properly, leading to incorrect boundary checking. An attacker may be able to use specially crafted log messages inserted via UDP which overflows the buffer.

This problem has been fixed in version 1.5.15-1.1 for the current
stable distribution (woody), in version 1.4.0rc3-3.2 for the old
stable distribution (potato) and version 1.5.21-1 for the unstable
distribution (sid).

We recommend that you upgrade your syslog-ng package immediately.

wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
will update the internal database
apt-get upgrade
will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
