CVE-2026-82330
Gimp: heap out-of-bounds read in pvr vq (compressed) decoder due to missing bounds check
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.
Fixes and workarounds
Workaround
To mitigate this vulnerability, do not open PVR files from untrusted sources with GIMP.
