centericq in testing is vulnerable to multiple security holes:
CVE-2005-2448
Multiple endianness errors in libgadu, which is embedded in centericq,
allow remote attackers to cause a denial of service (invalid behaviour in
applications) on big-endian systems.
CVE-2005-2370
Multiple memory alignment errors in libgadu, which is embedded in
centericq, allows remote attackers to cause a denial of service (bus error)
on certain architectures such as SPARC via an incoming message.
CVE-2005-2369
Multiple integer signedness errors in libgadu, which is embedded in
centericq, may allow remote attackers to cause a denial of service
or execute arbitrary code.
CVE-2005-1914
centericq creates temporary files with predictable file names, which
allows local users to overwrite arbitrary files via a symlink attack.
For the testing distribution (etch) this is fixed in version 4.20.0-8etch1
For the unstable distribution (sid) this is fixed in version 4.20.0-9
This upgrade is recommended if you use centericq.
If you have the secure testing lines in your sources.list, you can update by running this command as root:
apt-get update && apt-get install centericq
The Debian testing security team does not track security issues for then stable (sarge) and oldstable (woody) distributions. If stable is vulnerable, the Debian security team will make an announcement once a fix is ready.
To use the Debian testing security archive, add the following lines to your /etc/apt/sources.list:
deb http://secure-testing.debian.net/debian-secure-testing etch/security-updates main contrib non-free
