Local privilege escalation due to incorrect assignment of privileges of temporary files in the update mechanism of G DATA Management Server. This vulnerability allows a local, unprivileged attacker to escalate privileges on affected installations by placing a crafted ZIP archive in a globally writable directory, which gets unpacked in the context of SYSTEM and results in arbitrary file write.
