CriticalCVSS 10.0 · v2.0—Proof of concept Fix available

Noroxi assessment

Priority: This week (action score 66/100)

  • 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: 86.4% (FIRST EPSS); higher than 99.7% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: samba (Debian:12) 2.2.8; samba (Debian:3.0) 2.2.3a-12.1.

Don’t wait for the next maintenance window. Upgrade to samba (Debian:12) 2.2.8; samba (Debian:3.0) 2.2.3a-12.1 or later.
