CVE CAN-2005-1852


1. Systems affected:

All versions of Kopete as included in
KDE 3.3.x up to including 3.4.1. KDE 3.2.x and older
are not affected.



2. Overview:

Kopete contains a copy of libgadu that is used if
no compatible version is installed in the system. Several
input validation errors have been reported in libgadu
that can lead to integer overflows and remote DoS or
arbitrary code execution.


3. Impact:

If the Gadu-Gadu protocol handler in Kopete is used,
remote users can DoS the Kopete client or possibly even
execute arbitrary code.


4. Solution:

Source code patches have been made available that update
the included copy of libgadu to 1.6rc3 which fix these
vulnerabilities. Contact your OS vendor / binary package provider
for information about how to obtain updated binary packages.
