Title: Avira AntiVir Personal Edition Classic Update.EXE Local Privilege Escalation Vulnerability
Severity: MODERATE
Description:
AntiVir Personal Edition Classic is an application for detecting viruses, worms, and malware. It is written for Microsoft Windows.
AntiVir Personal Edition Classic is prone to a local privilege-escalation vulnerability because the application fails to sanitize user-supplied input to the progress-bar control of the 'update.exe' process. An attacker may manipulate user messages 'PBM_GETRANGE' and 'PBM_SETRANGE' as well as the 'IParam' parameter of the progress-bar control to write an arbitrary value to an arbitrary memory location.
A local attacker can exploit this issue to execute arbitrary code with SYSTEM privileges. This may facilitate a complete compromise of the affected computer.
AntiVir Personal Edition Classic version 7 is vulnerable; other versions may also be affected.
