Noroxi assessment

Priority: Monitor (action score 28/100)

  • 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: 7.4% (FIRST EPSS); higher than 94.5% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: tiff (Alpine:v3.10) 4.0.8-r1; tiff (Alpine:v3.3) 4.0.8-r0; tiff (Debian:12) 4.0.8-3.

Low priority for now. Upgrade to tiff (Alpine:v3.10) 4.0.8-r1; tiff (Alpine:v3.3) 4.0.8-r0; tiff (Debian:12) 4.0.8-3 or later.
