Adobe Flash Player Integer Underflow Vulnerablity

Published Updated By the CyberSecBulletin desk

CVE-2014-0497 is a critical-severity integer underflow (wrap or wraparound) vulnerability in flash_player from Adobe, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 11.7.700.261 as the first without the flaw, so updating flash_player to that release or later removes the exposure. CISA added it to the Known Exploited Vulnerabilities catalogue on September 17, 2024, 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 flash_player to 11.7.700.261 or a later version.
  2. Update Chrome to 32.0.1700.107 or a later version.
  3. CISA's required action: The impacted product is end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue utilization of the product.
  4. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Integer Underflow (Wrap or Wraparound)

The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.
