Adobe Reader and Acrobat ICC Processing Integer Overflow Vulnerability
Adobe Reader and Acrobat are portable document format (PDF) readers and processors. For more information, please visit the following pages:
Remote exploitation of a integer overflow vulnerability in Adobe Systems Inc.'s Reader could allow an attacker to execute arbitrary code with the privileges of the current user.
The vulnerability occurs during the parsing of certain records embedded within an ICC profile. The size value of the record is used as part of integer calculation. The result of the integer calculation may lead to a stack buffer overflow condition. This can result in 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 created by an attacker. 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.
Adobe Reader 9.4.5 and prior are vulnerable.
