# CVE-2026-82330: Gimp: heap out-of-bounds read in pvr vq (compressed) decoder due to missing bounds check

Status: published. Published: 2026-08-28. Updated: 2026-11-06.

A flaw was found in the file-pvr plugin in GIMP. When processing a specially crafted PVR image file, the VQ (compressed) decoder does not properly perform memory bounds checking. This missing validation results in 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.

## Remediation

- workaround: To mitigate this vulnerability, do not open PVR files from untrusted sources with GIMP. (source: CNA: redhat)
