Detailsinfo

A vulnerability classified as problematic was found in Red Hat Enterprise Linux (affected version not known). This vulnerability affects some unknown functionality of the component XMC Thumbnail Loader. The manipulation with an unknown input leads to a integer overflow vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect availability. CVE summarizes:

A flaw was found in GIMP’s X cursor (XMC) thumbnail loader. When GIMP generates a thumbnail for a crafted XMC file, it allocates a pixel buffer using a width * height size computed in 32-bit signed arithmetic. If that product overflows, the allocation is smaller than the true image extent. A subsequent GEGL buffer read uses the unwrapped dimensions and performs an out-of-bounds read on the heap (CWE-125), after integer overflow in the size calculation (CWE-190). This can crash GIMP or corrupt process memory.

The advisory is shared for download at access.redhat.com. This vulnerability was named CVE-2026-106061 since 10/06/2026. The exploitation appears 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. The current price for an exploit might be approx. USD $5k-$25k (estimation calculated on 10/07/2026).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
