HighCVSS 8.8 · v3.1—Proof of concept Fix available

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: 25% (FIRST EPSS); higher than 97.9% of all records.
  • Anyone who can reach it over the internet 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: flash-plugin (Red Hat:rhel_extras:5::client) 0:11.2.202.577-1.el5; flash-plugin (Red Hat:rhel_extras:6) 0:11.2.202.577-1.el6_7; flash-player (SUSE:Linux Enterprise Desktop 11 SP4) 11.2.202.577-0.38.1.

Add it to your regular patch cycle. Upgrade to flash-plugin (Red Hat:rhel_extras:5::client) 0:11.2.202.577-1.el5; flash-plugin (Red Hat:rhel_extras:6) 0:11.2.202.577-1.el6_7; flash-player (SUSE:Linux Enterprise Desktop 11 SP4) 11.2.202.577-0.38.1 or later.
