Noroxi assessment

Priority: Monitor (action score 18/100)

  • 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: 3.5% (FIRST EPSS); higher than 89.5% of all records.
  • Fixed version: acroread (Red Hat:rhel_extras:4) 0:9.4.6-1.el4; acroread-plugin (Red Hat:rhel_extras:4) 0:9.4.6-1.el4; acroread (Red Hat:rhel_extras:5::client) 0:9.4.6-1.el5.

Low priority for now. Upgrade to acroread (Red Hat:rhel_extras:4) 0:9.4.6-1.el4; acroread-plugin (Red Hat:rhel_extras:4) 0:9.4.6-1.el4; acroread (Red Hat:rhel_extras:5::client) 0:9.4.6-1.el5 or later.
