Detailsinfo

A vulnerability was found in ImageMagick up to 7.1.2-15 and classified as critical. Affected by this issue is some unknown functionality of the component SIXEL Decoder. 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:

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16, an integer overflow vulnerability exists in the SIXEL decoer. The vulnerability allows an attacker to perform an out of bounds via a specially crafted image. This vulnerability is fixed in 7.1.2-16.

The advisory is available at github.com. This vulnerability is handled as CVE-2026-28493 since 02/27/2026. The exploitation is known to be difficult. The attack may be launched remotely. No form of authentication is required for exploitation. Successful exploitation requires user interaction by the victim. The technical details are unknown and an exploit is not available.
