Remote exploitation of a heap buffer overflow vulnerability in Adobe Systems Inc.'s Acrobat and Reader could allow an attacker to execute arbitrary code with the privileges of the current user. Adobe Reader and Acrobat are portable document format (PDF) readers and processors.
The vulnerability occurs when parsing a specially crafted OpenType font embedded in a PDF file. During the parsing of an OpenType font, Adobe Reader fails to properly validate a specific field, which triggers a heap overflow. This can lead to the execution of arbitrary code.
Exploitation of this vulnerability results in the execution of arbitrary code with the privileges of the user viewing a Web page or opening a PDF file. Since PDF files can be embedded into Web pages and parsed without interaction by default, this vulnerability can be exploited as a typical browser vulnerability. To exploit this vulnerability, a targeted user must load a malicious Web page that an attacker created. An attacker typically accomplishes this via social engineering or injecting content into compromised, trusted sites. After the user visits the malicious Web page, no further user interaction is needed.
The following products are vulnerable:
