Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Red Hat/gimp, Red Hat/gimp:2.8/gimp.
  2. 2Review the reported fix. Source-reported workaround: Users should avoid opening untrusted DirectDraw Surface (DDS) image files with GIMP. As a general security practice, only process files from trusted sources. If GIMP is not essential, consider removing the `gimp` package to eliminate this attack vector.

Upstream source description

A heap-based buffer overflow vulnerability exists in the GIMP DDS (DirectDraw Surface) file parser. When a crafted DDS file declares a D3D9 pixel format but sets a lower bits-per-pixel (bpp) value in the header, the loader allocates an undersized heap buffer. Subsequent pixel data consumption at the real format's stride causes a write past the heap buffer boundary, leading to heap metadata corruption and potential code execution.
