HighCVSS 7.8 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 32/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 3.2% (FIRST EPSS); higher than 88.5% 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: tiff (Debian:12) 4.0.6-3; tiff (Debian:7) 4.0.2-6+deb7u7; libtiff (Red Hat:enterprise_linux:6::client) 0:3.9.4-18.el6_8.

Low priority for now. Upgrade to tiff (Debian:12) 4.0.6-3; tiff (Debian:7) 4.0.2-6+deb7u7; libtiff (Red Hat:enterprise_linux:6::client) 0:3.9.4-18.el6_8 or later.
