Adobe Flash Player Unspecified

CVE-2011-0609 is a high-severity vulnerability in Flash Player from Adobe, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. Affected Flash Player versions: 10.2.154.13 and earlier; 10.1.106.16 and earlier. The record does not name a fixed version, so check the vendor advisory. CISA added it to the Known Exploited Vulnerabilities catalogue on June 8, 2022, which means attacks have been observed in the wild.

Patch now

Attackers are already exploiting this vulnerability, according to CISA.

What to do

  1. Update Chrome to 10.0.648.134 or a later version.
  2. CISA's required action: The impacted product is end-of-life and should be disconnected if still in use.
  3. Read the advisory on adobe.com for workarounds and exact fixed builds.
  4. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
