CVE ID :CVE-2026-80101
Published : Aug. 25, 2026, 9:18 p.m. | 1 hour, 10 minutes ago
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.
Severity: 4.4 | MEDIUM
