Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for GNOME/gimp, Red Hat/gimp, Red Hat/gimp:2.8/gimp.
  2. 2Review the reported fix. Source-reported workaround: To mitigate this vulnerability, do not open ICO files from untrusted sources with GIMP.

Upstream source description

A flaw was found in the file-ico plugin in GIMP. When processing a specially crafted ICO image file, the plugin does not properly validate the used_clrs (palette count) parameter. This incorrect validation leads to improper memory bounds checking, resulting in a heap out-of-bounds read. This issue can result in an application crash, leading to a denial of service or a limited information disclosure of heap memory contents.
