Who should care

Users of GIMP, especially those processing PSD files from untrusted sources, should apply patches promptly. This includes developers, designers, and anyone using GIMP for image processing. The vulnerability has a high severity score and could lead to significant impact if exploited.

Technical summary

An integer overflow in read_RLE_channel() can cause an undersized heap allocation for the RLE row-length table. Subsequent per-row writes can then corrupt heap memory, potentially leading to denial of service or arbitrary code execution. The vulnerability is in GIMP's PSD parser and affects users processing PSD files from untrusted sources, particularly developers, designers, and others using GIMP for image processing. This could lead to significant impact if exploited, emphasizing the need for prompt patching and restricting PSD file processing to trusted sources.

Defensive priority

High priority due to potential for code execution and denial of service

Recommended defensive actions

  • Apply patches promptly
  • Restrict PSD file processing to trusted sources
  • Monitor GIMP updates and security advisories
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
