MediumCVSS 5.5 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 23/100)

  • 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: 3.7% (FIRST EPSS); higher than 90% 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: gd (Alpine:v3.3) 2.2.4-r0; libgd2 (Debian:12) 2.2.4-1; libgd2 (Debian:7) 2.0.36~rc1~dfsg-6.1+deb7u8.

Low priority for now. Upgrade to gd (Alpine:v3.3) 2.2.4-r0; libgd2 (Debian:12) 2.2.4-1; libgd2 (Debian:7) 2.0.36~rc1~dfsg-6.1+deb7u8 or later.
