CESA-2005:639: kdenetwork security update



Updated kdenetwork packages to correct a security flaw in Kopete are now available for CentOS Linux 4. This update has been rated as having critical security impact by the Red Hat Security Response Team.

The kdenetwork package contains networking applications for the K Desktop Environment. Kopete is a KDE instant messenger which supports a number of protocols including ICQ, MSN, Yahoo, Jabber, and Gadu-Gadu. Multiple integer overflow flaws were found in the way Kopete processes Gadu-Gadu messages. A remote attacker could send a specially crafted Gadu-Gadu message which would cause Kopete to crash or possibly execute arbitrary code. The Common Vulnerabilities and Exposures project assigned the name CAN-2005-1852 to this issue. In order to be affected by this issue, a user would need to have registered with Gadu-Gadu and be signed in to the Gadu-Gadu server in order to receive a malicious message. In addition, CentOS believes that the Exec-shield technology (enabled by default in CentOS Linux 4) would block attempts to remotely exploit this vulnerability. Note that this issue does not affect CentOS Linux 2.1 or 3. Users of Kopete should update to these packages which contain a patch to correct this issue.
