Noroxi assessment
Priority: Monitor (action score 27/100)
- Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 1.8% (FIRST EPSS); higher than 79.3% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: fontforge (AlmaLinux:8) 20200314-6.el8_10; fontforge (AlmaLinux:9) 20201107-6.el9; fontforge (Debian:10) 1:20170731~dfsg-1+deb10u1.
Low priority for now. Upgrade to fontforge (AlmaLinux:8) 20200314-6.el8_10; fontforge (AlmaLinux:9) 20201107-6.el9; fontforge (Debian:10) 1:20170731~dfsg-1+deb10u1 or later.
