Yahoo! Messenger YVerInfo ActiveX Buffer Overflows

high Nessus Plugin ID 25955

Synopsis

The remote Windows host has an ActiveX control that is affected by multiple buffer overflow vulnerabilities.

Description

The remote host contains the 'YVerInfo' ActiveX control, distributed as part of the Yahoo! services suite typically downloaded with the installer for Yahoo! Messenger.

The version of this control installed on the remote host reportedly contains buffer overflows involving its 'fvCom' and 'info' methods.
If an attacker can trick a user on the affected host into visiting a specially crafted web page, this issue could be leveraged to execute arbitrary code on the host subject to the user's privileges.

Solution

Either disable the use of this ActiveX control from within Internet Explorer by setting its kill bit or upgrade to Yahoo! Messenger version 8.1.0.419 (version 2007.8.27.1 of the YVerInfo control itself) or later.
