Use-after-free in Adobe Flash Player allows remote attackers to execute arbitrary code via unspecified vectors.

Vulnerability

A use-after-free vulnerability exists in Adobe Flash Player versions before 18.0.0.324 and 19.x through 20.x before 20.0.0.267 on Windows and OS X, and before 11.2.202.559 on Linux. It also affects Adobe AIR before 20.0.0.233, AIR SDK before 20.0.0.233, and AIR SDK & Compiler before 20.0.0.233. The flaw is triggered via unspecified vectors [1][2].

Exploitation

An attacker could exploit this vulnerability by enticing a user to open a specially crafted Flash file. This can be achieved through a malicious web page or email. No authentication is required, and user interaction is necessary [1].

Impact

Successful exploitation allows arbitrary code execution in the context of the affected user, potentially leading to full system compromise [2].

Mitigation

Adobe released Flash Player 18.0.0.324, 20.0.0.267, and 11.2.202.559, as well as AIR 20.0.0.233, to address this issue. Red Hat and Gentoo have also issued updates [1][2]. Users should update immediately; no workaround is available.
