A privilege escalation (PE) vulnerability in the Tencent iOA app thru 210.9.28693.621001 on Windows devices enables a local user to execute programs with elevated privileges. However, execution requires that the local user is able to successfully exploit a race condition.

ZoneAlarm Anti-Ransomware before version 1.0.713 copies files for the report from a directory with low privileges. A sophisticated timed attacker can replace those files with malicious or linked content, such as exploiting CVE-2020-0896 on unpatched systems or using symbolic links. This allows an unprivileged user to enable escalation of privilege via local access.
