Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for gimp, Red Hat/gimp.
  2. 2Review the reported fix. Source-reported workaround: To mitigate this vulnerability, users should avoid opening untrusted or suspicious PSD image files with GIMP. As a general security practice, it is recommended to only process image files from trusted sources.

Upstream source description

A flaw was found in GIMP's PSD file format plugin. This vulnerability, an unsigned integer underflow in the `block_rem` variable, occurs when a user opens a specially crafted `.psd` image file. The underflow leads to parser confusion, enabling an attacker to inject arbitrary data as layer resource blocks. This can ultimately result in arbitrary code execution, allowing the attacker to run malicious code on the victim's system.
