Detailsinfo

A vulnerability was found in GIMP (affected version unknown) and classified as problematic. Affected by this issue is an unknown functionality of the component Decompression. The manipulation with an unknown input leads to a integer overflow vulnerability. Using CWE to declare the problem leads to CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. Impacted is confidentiality, integrity, and availability. CVE summarizes:

A flaw was found in GIMP. An attacker can cause a Denial of Service (DoS) or potentially disclose sensitive memory contents by convincing a user to open or preview a specially crafted Bohemia Interactive (PAA) texture file. Due to an integer overflow when calculating image dimensions during file decompression, the application allocates an undersized memory buffer. Subsequent processing reads memory past the buffer boundary, terminating the plug-in process unexpectedly.

The advisory is shared for download at access.redhat.com. This vulnerability is handled as CVE-2026-62438 since 07/14/2026. The exploitation is known to be easy. The attack needs to be approached locally. Successful exploitation requires user interaction by the victim. There are neither technical details nor an exploit publicly available.
