Noroxi assessment

Priority: Monitor (action score 23/100)

  • 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: 3.7% (FIRST EPSS); higher than 90.1% of all records.
  • Someone with local access to the system 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: vorbis-tools (Debian:13) 1.4.3-1.

Low priority for now. Upgrade to vorbis-tools (Debian:13) 1.4.3-1 or later.
