CVE-2015-3043

Adobe Flash Player's unpatched memory corruption flaw allowed remote code execution, proving that end-of-life software remains a perpetual security liability.

Adobe Flash Player suffered a memory corruption vulnerability enabling remote code execution, a flaw that persisted because the product reached end-of-life in December 2020 with no further patches. DIB organizations must care because unpatched, discontinued software remains a perpetual security liability, allowing attackers to execute arbitrary code without needing a zero-day exploit. The takeaway is to immediately remove all end-of-life software from the environment and replace it with supported alternatives to avoid exploitation.

Shame score — Adobe continued shipping a product with known critical vulnerabilities long after its end-of-life, and the flaw was actively exploited in the wild, demonstrating severe negligence in software lifecycle management.
