Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Two security issues have been discovered in the DCC protocol support code of kvirc, a KDE-based next generation IRC client, which allow the overwriting of local files through directory traversal and the execution of arbitrary code through a format string attack.
