Original Release Date: 2011-01-13 | Last Revised: 2011-01-13

Overview

ICQ 7 does not verify the origin of automatic updates which may allow a remote attacker to execute arbitrary code.

Description

According to ICQ's website: "ICQ, the pioneer of Instant Messaging (IM), now offers the optimal integration between Instant Messaging and Social Networks with the newest ICQ version – the Social Messaging tool that can be downloaded free of charge at www.icq.com." ICQ 7 checks for updates on start-up but does not verify the origin of updates through digital signatures or other means.

Impact

By successfully spoofing the update site, an attacker may be able to execute arbitrary code with the privileges of the user.
