Adobe Acrobat and Adobe Reader contain a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code.
The vulnerability exists due to insufficient bounds checks on user-supplied input. An unauthenticated, remote attacker could exploit this vulnerability by convincing a targeted user to open a crafted file or convince a user to visit a website designed to submit crafted input to the affected software. Processing such crafted input could trigger a buffer overflow condition that could allow the attacker to execute arbitrary code on the targeted system.
Adobe has confirmed the vulnerability and released software updates.

Technical details are not available.
To exploit this vulnerability, an attacker must persuade a user to open a malicious document that contains crafted Flash content or visit a crafted web page. The attacker may provide a file or a link that directs a user to a malicious site and use misleading language or instructions to persuade the user to open the file or follow the provided link.
The vulnerability has also been documented in IntelliShield Security Activity bulletin 30736.
