The remote host is missing an update to libmail-audit-perl announced via advisory DSA 960-2. This update only corrects the update for sarge, the version in woody is correct. Niko Tyni discovered that the Mail::Audit module, a Perl library for creating simple mail filters, logs to a temporary file with a predictable filename in an insecure fashion when logging is turned on, which is not the case by default. For the old stable distribution (woody) these problems have been fixed in version 2.0-4woody1.

For the stable distribution (sarge) these problems have been fixed in version 2.1-5sarge2. For the unstable distribution (sid) these problems have been fixed in version 2.1-5.1. We recommend that you upgrade your libmail-audit-perl package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20960-2
