<net-irc/kvirc-4.1_pre4693 allows for remote execution of KVirc commands.
glsa request filed.
The IRC Protocol component in KVIrc 3.x and 4.x before r4693 does not
properly handle \ (backslash) characters, which allows remote
authenticated users to execute arbitrary CTCP commands via vectors
involving \r and \40 sequences, a different vulnerability than
CVE-2010-2451 and CVE-2010-2452.
