Noroxi assessment

Priority: Monitor (action score 25/100)

  • 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: 17.9% (FIRST EPSS); higher than 97.2% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: ethereal (Red Hat:enterprise_linux:3::as) 0:0.10.5-0.30E.2; ethereal-debuginfo (Red Hat:enterprise_linux:3::as) 0:0.10.5-0.30E.2; ethereal-gnome (Red Hat:enterprise_linux:3::as) 0:0.10.5-0.30E.2.

Low priority for now. Upgrade to ethereal (Red Hat:enterprise_linux:3::as) 0:0.10.5-0.30E.2; ethereal-debuginfo (Red Hat:enterprise_linux:3::as) 0:0.10.5-0.30E.2; ethereal-gnome (Red Hat:enterprise_linux:3::as) 0:0.10.5-0.30E.2 or later.
