A vulnerability in Adobe Flash Player could allow an unauthenticated, remote attacker to bypass security restrictions.
The vulnerability is due to insufficient validation of user-supplied input by the affected software. An attacker could exploit this vulnerability by convincing a user to visit a malicious website. An exploit could allow the attacker to trigger a memory leak, which could be leveraged to bypass the address space layout randomization (ASLR) protection on a targeted system. A successful exploit could be used to conduct further attacks.
Adobe has confirmed the vulnerability and released software updates.

Technical details are not available.
To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious site and use misleading language or instructions to persuade the user to follow the provided link. The requirement for user interaction could limit the possibility of a successful exploit.
