Adobe Acrobat and Reader contain a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code with the privileges of the user.
The vulnerability is due to a lack of boundary checking in the affected products. An unauthenticated, remote attacker could exploit this vulnerability by convincing a targeted user to view a crafted .pdf file with affected software. Opening the malicious file could trigger a buffer overflow that is exploitable for code execution with the privileges of the user.
Functional exploit code is circulating in the wild.
Adobe has confirmed this vulnerability and released updated software.
