Yahoo! Messenger < YVerInfo ActiveX Buffer Overflow



The remote Windows host has an ActiveX control that is affected by a buffer overflow vulnerability.


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 a boundary error. If an attacker can trick a user on the affected host into visiting a specially-crafted web page, he may be able to leverage this issue to execute arbitrary code on the host subject to the user's privileges.


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