Noroxi assessment
Priority: Monitor (action score 25/100)
- Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 16.4% (FIRST EPSS); higher than 96.9% of all records.
- No special conditions are required; it is repeatable.
- Fixed version: freetype (Debian:12) 2.2.1-1; freetype (Debian:3.0) 2.0.9-1woody1; freetype (Debian:3.1) 2.1.7-2.5.
Low priority for now. Upgrade to freetype (Debian:12) 2.2.1-1; freetype (Debian:3.0) 2.0.9-1woody1; freetype (Debian:3.1) 2.1.7-2.5 or later.

Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
