GLSA-200709-02 : KVIrc: Remote arbitrary code execution

high Nessus Plugin ID 26042

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200709-02 (KVIrc: Remote arbitrary code execution)

 Stefan Cornelius from Secunia Research discovered that the 'parseIrcUrl()' function in file src/kvirc/kernel/kvi_ircurl.cpp does not properly sanitise parts of the URI when building the command for KVIrc's internal script system.
 Impact :

 A remote attacker could entice a user to open a specially crafted irc:// URI, possibly leading to the remote execution of arbitrary code with the privileges of the user running KVIrc. Successful exploitation requires that KVIrc is registered as the default handler for irc:// or similar URIs.
 Workaround :

 There is no known workaround at this time.

Solution

All KVIrc users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-irc/kvirc-3.2.6_pre20070714'
