Buffer overflow in Trend Micro URL Filtering Engine (TMUFE) in OfficeScan 8.0 before SP1 Patch 5 - Build 3510, possibly tmufeng.dll before 3
Buffer overflow in Trend Micro URL Filtering Engine (TMUFE) in OfficeScan 8.0 before SP1 Patch 5 - Build 3510, possibly tmufeng.dll before 3.0.0.1029, allows attackers to cause a denial of service (crash or OfficeScan hang) via unspecified vectors. NOTE: it is likely that this issue also affects tmufeng.dll before 2.0.0.1049 for OfficeScan 10.0.

Fix versions compiled from the vendor, package registries and Microsoft. Verify the vendor's note before upgrading.
No fix version is recorded for this entry. Check the references for vendor advisories.
Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.
FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).
Patch and commit links
