Detail

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.
