Jul893 Patched -

Implement a virtual patch using a Web Application Firewall (WAF) rule that blocks any request with a timestamp in the If-None-Match header that deviates from server time by more than 10 minutes.

The most dangerous flaw identified in Jul893 was a heap-based buffer overflow in its request-parsing engine. By sending a specially crafted packet to any service relying on Jul893, an unauthenticated attacker could trigger arbitrary code execution with system-level privileges.
