http://secunia.com/advisories/29138/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
ICQ 6.x
http://secunia.com/product/14880/

DESCRIPTION:
B0B has discovered a vulnerability in ICQ, which can be exploited by
malicious people to compromise another user's system.

The vulnerability is caused due to a format string error when
generating HTML code to display messages in the embedded Internet
Explorer component, which can be exploited by sending specially
crafted messages containing format string specifiers to another
user.

Successful exploitation allows the execution of arbitrary code.

The vulnerability is confirmed in ICQ 6 build 6043. Other versions
may also be affected.

SOLUTION:
Enable the "Accept messages only from contacts" option and remove
untrusted users from your contact list.

If the "Ask me before displaying messages from people I don't know"
option is enabled, discard incoming messages.

PROVIDED AND/OR DISCOVERED BY:
