A type confusion issue was addressed with improved state handling.

Noroxi assessment

Priority: Monitor (action score 27/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 34.1% (FIRST EPSS); higher than 98.3% 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: webkit2gtk3 (AlmaLinux:8) 2.50.4-1.el8_10; webkit2gtk3-devel (AlmaLinux:8) 2.50.4-1.el8_10; webkit2gtk3-jsc (AlmaLinux:8) 2.50.4-1.el8_10.

Low priority for now. Upgrade to webkit2gtk3 (AlmaLinux:8) 2.50.4-1.el8_10; webkit2gtk3-devel (AlmaLinux:8) 2.50.4-1.el8_10; webkit2gtk3-jsc (AlmaLinux:8) 2.50.4-1.el8_10 or later.
