http://secunia.com/advisories/product/14634/

DESCRIPTION:
Gjoko 'LiquidWorm' Krstic has discovered a vulnerability in KVIrc,
which potentially can be exploited by malicious people to compromise
a user's system.

The vulnerability is caused due to a format string error while
processing URIs and can be exploited e.g. by tricking a user into
opening a specially crafted "irc://" URI.

Successful exploitation may allow execution of arbitrary code, but
requires that KVIrc is the default handler for IRC URIs.

The vulnerability is confirmed in version 3.4.0 on Windows. Other
versions may also be affected.

SOLUTION:
Do not follow untrusted links or browse untrusted websites.
