iDefense Security Advisory 10.30.08 http://labs.idefense.com/intelligence/vulnerabilities/ OCT 30, 2008
Adobe PageMaker is document layout application, and is commonly used for desktop publishing. For more information see the vendor's website found at the following address.
Remote exploitation of a stack buffer overflow vulnerability in Adobe Systems Inc.'s PageMaker could allow an attacker to execute arbitrary code with the privileges of the current user.
A vulnerability exists within the handling of PMD files, the native file format for storing PageMaker documents. When parsing a malformed PMD file, data from the file is copied into a buffer without proper validation. This results in an exploitable stack based buffer overflow.
Exploitation of this vulnerability could allow an attacker to execute arbitrary code with the privileges of the user opening the file. Exploitation would require that an attacker hosts a maliciously crafted document on a website and entice users to visit the site. An attacker could also e-mail the malicious document and use social engineering techniques to trick the e-mail recipient into opening the document.
iDefense has confirmed the existence of this vulnerability in Adobe PageMaker version 7.0.1 with the CVE-2007-5169 patch applied. Previous versions may also be affected. However, Adobe InDesign CS, the successor to PageMaker, is not affected.
iDefense is currently unaware of any workarounds for this issue.
