Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Red Hat/gimp, GNOME/gimp, Red Hat/gimp:2.8/gimp.
  2. 2Review the reported fix. Source-reported workaround: To mitigate this vulnerability, do not navigate to directories containing PSD files from untrusted sources using the GIMP file chooser. Additionally, users can disable thumbnail generation in the preferences to prevent the vulnerable code path from being reached.

Upstream source description

A flaw was found in the file-psd plugin in GIMP. When generating a thumbnail preview for a specially crafted PSD (Photoshop Document) image file, an integer overflow occurs during the multiplication of values from an embedded JPEG header. This leads to an undersized heap allocation, resulting in a heap-based buffer overflow when the image data is decoded. This buffer overflow corrupts adjacent heap objects, allowing for a controlled memory write that can result in an application crash or arbitrary code execution.
