Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
GIMP XWD File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of XWD files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-27823.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

How this class of weakness works · CWE-122

Data overflows a buffer allocated on the heap, corrupting neighbouring heap structures and allocator metadata that a patient attacker can groom into control of execution. It is subtler than a stack overflow but just as dangerous. The fix is validating lengths before every write and using safe allocators and bounded operations.

GIMP version containing the fix (any version after 3.0.4 that includes commit 5c3e2122)

  1. Apply the vendor patch from commit 5c3e2122d53869599d77ef0f1bdece117b24fd7c to fix the heap-based buffer overflow in XWD file parsing: https://gitlab.gnome.org/GNOME/gimp/-/commit/5c3e2122d53869599d77ef0f1bdece117b24fd7c
  2. Alternatively, upgrade to a GIMP version that incorporates this security fix
  3. For Debian 11 systems, apply any available Debian security updates for the gimp package via 'apt update && apt upgrade'
  4. Do not open untrusted or unexpected XWD files in GIMP until the patch is applied
  5. Verify the fix by confirming the patched version or successful patch application
