Adobe Reader and Acrobat PDF File Parsing Arbitrary Code Execution Vulnerability
Adobe Acrobat and Reader contain a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code.
This vulnerability is due to improper handling of PDF documents. An unauthenticated, remote attacker could exploit this vulnerability by convincing a user to view a malicious document. A successful attack could allow the attacker to execute arbitrary code with the privileges of the user.
Adobe confirmed the vulnerability in a security bulletin and released software updates.
Indicators of Compromise
The following Adobe products are affected:
Adobe Reader versions 8.2.2 and prior
Adobe Acrobat versions 8.2.2 and prior
Adobe Reader versions 9.3.2 and prior
Adobe Acrobat versions 9.3.2 and prior
This vulnerability is due to improper handling of PDF documents. An unauthenticated, remote attacker could exploit the vulnerability by convincing a user to view a malicious PDF file. When processed, the file could cause memory corruption. The attacker could leverage the memory corruption to execute arbitrary code with the privileges of the user.
Further technical information is not available.
To exploit this vulnerability, an attacker must convince a user to view a malicious PDF document. Attackers may deliver documents to users as attachments to e-mail messages or via links in e-mail or instant messages. If the user views the file, the attacker could trigger the execution of arbitrary code. Depending on the user's privileges, the attacker could execute code that results in complete system compromise.
