HighCVSS 7.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 3.4% (FIRST EPSS); higher than 89.2% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: gdk-pixbuf (Alpine:v3.10) 2.36.6-r1; gdk-pixbuf (Alpine:v3.5) 2.36.6-r0; gdk-pixbuf (Debian:12) 2.36.10-1.

Low priority for now. Upgrade to gdk-pixbuf (Alpine:v3.10) 2.36.6-r1; gdk-pixbuf (Alpine:v3.5) 2.36.6-r0; gdk-pixbuf (Debian:12) 2.36.10-1 or later.
