Multivendor Vulnerability Alert
Adobe Flash Player and AIR Use-After-Free Arbitrary Code Execution Vulnerability
A vulnerability in Adobe Flash Player and AIR could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system.
The vulnerability is due to improper memory operations performed by the affected software. An attacker could exploit this vulnerability by convincing a user to visit a malicious web page that contains crafted Flash content. A successful exploit could allow to cause a use-after-free condition that the attacker could use to execute arbitrary code on the system.
Adobe has confirmed the vulnerability and released updated software.
