Stack-based buffer overflow in Adobe Flash Player before 13.0.0.259 and 14.x and 15.x before 15.0.0.246 on Windows and OS X and before 11.2.
Noroxi assessment
Priority: This week (action score 67/100)
- CISA has confirmed exploitation in the wild (Apr 13, 2022). Remediation deadline for US federal agencies: May 4, 2022.
- Probability of exploitation in the next 30 days: 20.7% (FIRST EPSS); higher than 97.4% of all records.
- Someone with local access to the system 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) 0:11.2.202.425-1.el5; flash-plugin (Red Hat:rhel_extras:6) 0:11.2.202.425-1.el6.
Don’t wait for the next maintenance window. Upgrade to flash-plugin (Red Hat:rhel_extras:5::client) 0:11.2.202.425-1.el5; flash-plugin (Red Hat:rhel_extras:6) 0:11.2.202.425-1.el6 or later.
