# CVE-2014-0502: Adobe Flash Player Double Free Vulnerablity

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run Adobe Flash Player. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-09-17, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-10-08 ; treat that as the outer limit, not the target.
- EPSS 24.8% , percentile 98: FIRST’s model estimates a 24.8% chance of exploitation activity in the next 30 days, higher than 98% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Needs a user to click or open something. Phishing makes that realistic, but it is not wormable.

## What it is

Double free vulnerability in Adobe Flash Player before 11.7.700.269 and 11.8.x through 12.0.x before 12.0.0.70 on Windows and Mac OS X and before 11.2.202.341 on Linux, Adobe AIR before 4.0.0.1628 on Android, Adobe AIR SDK before 4.0.0.1628, and Adobe AIR SDK & Compiler before 4.0.0.1628 allows remote attackers to execute arbitrary code via unspecified vectors, as exploited in the wild in February 2014.
