CriticalCVSS 9.1 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 37/100)

  • 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: 4.2% (FIRST EPSS); higher than 91.1% 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: ImageMagick (SUSE:Linux Enterprise Desktop 12 SP1) 6.8.8.1-33.1; ImageMagick (SUSE:Linux Enterprise Software Development Kit 11 SP4) 6.4.3.6-7.48.1.

Low priority for now. Upgrade to ImageMagick (SUSE:Linux Enterprise Desktop 12 SP1) 6.8.8.1-33.1; ImageMagick (SUSE:Linux Enterprise Software Development Kit 11 SP4) 6.4.3.6-7.48.1 or later.
