Vulnerability Spotlight: Issue in Accusoft ImageGear could lead to memory corruption, code execution



Emmanuel Tacheau of Cisco Talos discovered these vulnerabilities. Blog by Jon Munshaw. 

Cisco Talos recently discovered a use-after-free vulnerability in Accusoft ImageGear's PSD header processing function. 

The ImageGear library is a document-imaging developer toolkit that allows users to create, edit, annotate and convert various images. It supports more than 100 file formats such as DICOM, PDF and Microsoft Office. 

This vulnerability, TALOS-2022-1526 (CVE-2022-29465) could allow an attacker to cause a use-after-free condition by tricking the targeted user into opening a malformed .psd file in the application. The vulnerability leads to out-of-bounds heap writes, which causes memory corruption and, possibly, code execution.

In adherence to Cisco’s vulnerability disclosure policy, Accusoft patched this issue and released an update for ImageGear.

Talos tested and confirmed Accusoft ImageGear, version 19.10, is affected by this vulnerability. 

The following Snort rules will detect exploitation attempts against this vulnerability: 60228 and 60229. Additional rules may be released in the future and current rules are subject to change, pending additional vulnerability information. For the most current rule information, please refer to your Cisco Secure Firewall Management Center or Snort.org.
