CVE-2023-6228: Libtiff: heap-based buffer overflow in cpstriptotile() in tools/tiffcp.c

Noroxi assessment

Priority: Monitor (action score 13/100)

  • 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: 0.39% (FIRST EPSS).
  • 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: libtiff (AlmaLinux:8) 4.0.9-32.el8_10; libtiff-devel (AlmaLinux:8) 4.0.9-32.el8_10; libtiff-tools (AlmaLinux:8) 4.0.9-32.el8_10.

Low priority for now. Upgrade to libtiff (AlmaLinux:8) 4.0.9-32.el8_10; libtiff-devel (AlmaLinux:8) 4.0.9-32.el8_10; libtiff-tools (AlmaLinux:8) 4.0.9-32.el8_10 or later.
