Description Jan Lieskovsky 2010-06-29 14:04:25 UTC
Multiple format string flaws were found in the way, KVIrc IRC client
processed certain Direct Client-to-Client (DCC) messages. A remote,
authenticated IRC user, could send a specially-crafted DCC message
to local KVIrc client, potentially leading to arbitrary code execution
with the privileges of the user running KVIrc, CVE-2010-2451.

A directory traversal flaw was found in the way, KVIrc IRC client
processed certain Direct Client-to-Client (DCC) messages. A remote,
authenticated IRC user, could send a specially-crafted DCC message
to local KVIrc client. This could allow an attacker to alter
integrity (overwrite) of some system files, CVE-2010-2452.

Comment 1 Jan Lieskovsky 2010-06-29 14:07:19 UTC
These flaws affect the versions of the kvirc package,
as present in the Fedora-12 and Fedora-13 -testing
repository (kvirc-4.0.0-1.fc12, kvirc-4.0.0-1.fc13).

Patch from [5] seems to be applicable to above versions.
Please fix.
