Noroxi assessment
Priority: Plan (action score 43/100)
- Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 18.5% (FIRST EPSS); higher than 97.1% of all records.
- Fixed version: acroread (Red Hat:rhel_extras:3) 0:8.1.7-1; acroread-plugin (Red Hat:rhel_extras:3) 0:8.1.7-1; acroread (Red Hat:rhel_extras:4) 0:8.1.7-1.el4.
Add it to your regular patch cycle. Upgrade to acroread (Red Hat:rhel_extras:3) 0:8.1.7-1; acroread-plugin (Red Hat:rhel_extras:3) 0:8.1.7-1; acroread (Red Hat:rhel_extras:4) 0:8.1.7-1.el4 or later.
