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% (FIRST EPSS); higher than 94.2% 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 (Debian:12) 4.0.8-2; tiff (Debian:7) 4.0.2-6+deb7u14; tiff3 (Debian:7) 3.9.6-11+deb7u6.

Low priority for now. Upgrade to tiff (Debian:12) 4.0.8-2; tiff (Debian:7) 4.0.2-6+deb7u14; tiff3 (Debian:7) 3.9.6-11+deb7u6 or later.
