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 SGI files from untrusted sources with GIMP.

Upstream source description

A flaw was found in the file-sgi plugin in GIMP. When processing an RLE-compressed SGI image, the plugin allocates memory for a row table. The image header dimensions (ysize and zsize) are read as 16-bit unsigned integers. If a crafted file sets both dimensions to their maximum value (65535), the multiplication ysize * zsize overflows the standard 32-bit int boundary before being passed to calloc. This integer overflow issue results in undefined behavior, aborting the plugin and causing a denial of service.
