Description
A flaw was found in the file-xwd plugin in GIMP. When processing a specially crafted XWD image file, the plugin validates the image width and bytes-per-line parameters independently rather than ensuring their combined values are consistent with the allocated buffer size. This incorrect validation leads to improper bounds checking, causing 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 into the produced image.

AI Analysis

Impact

The vulnerability is a heap out‑of‑bounds read in GIMP’s XWD loader caused by independent validation of image width and bytes‑per‑line, allowing the plugin to read beyond the allocated buffer. This can crash the application, causing a denial of service, or expose portions of heap memory in the produced image, leading to a limited information disclosure. The weakness is identified as CWE‑125.

Affected Systems

This flaw affects the GIMP file‑xwd plugin on Red Hat Enterprise Linux releases 6, 7, 8, and 9, as listed by the vendor. No specific patched versions are noted, so the vulnerability is presumed present in the versions shipped with those RHEL releases.

Risk and Exploitability

The CVSS score of 4.4 indicates moderate severity, and the EPSS score is unavailable, suggesting no known widespread exploitation. The flaw is not listed in CISA’s KEV catalog. Exploitation requires the attacker to deliver a specially crafted XWD file to a user who opens it with GIMP; thus the attack vector is local or social‑engineering based rather than remote network exposure. The potential impact is a service disruption or subtle information leak, but the risk is limited to environments where GIMP processes untrusted XWD files.

Remediation

Vendor Workaround

To mitigate this vulnerability, do not open XWD files from untrusted sources with GIMP.


OpenCVE Recommended Actions

  • Upgrade GIMP to the latest release that contains the fix for the XWD loader bug (consult the vendor or Red Hat advisories for release notes).
  • Avoid opening XWD files from untrusted or unknown sources with GIMP to prevent exploitation.
  • If the XWD loader is not required, disable or uninstall the file‑xwd plugin in GIMP to eliminate the attack surface.
