Debian Security Advisory DSA 960-3 security@debian.org

March 20th, 2006 http://www.debian.org/security/faq
- - --------------------------------------------------------------------------
Package : libmail-audit-perl
Vulnerability : insecure temporay file createion
Problem type : local
Debian-specific: no
CVE ID : CVE-2005-4536
Debian Bug : 344029
The former update caused temporary files to be created in the current
working directory due to a wrong function argument. This update will
create temporary files in the users home directory if HOME is set or
in the common temporary directory otherwise, usually /tmp. For
completeness below is a copy of the original advisory text:
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 2.0-4woody3.
For the stable distribution (sarge) these problems have been fixed in
version 2.1-5sarge4.
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.
