Doc Text:
A flaw was found in ImageMagick, a free and open-source software for editing and manipulating digital images. An attacker could craft a malicious image file that, when processed by the XCF decoder, triggers an integer overflow. This overflow leads to an out-of-bounds read, which can cause the application to crash, resulting in a denial of service.

Description OSIDB Bzimport 2026-07-01 19:02:01 UTC 
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-51 and 7.1.2-26, an integer overflow in the XCF decoder can result in an out of bounds read when a crafted image is read, potentially resulting in a crash. This issue has been fixed in versions 6.9.13-51 and 7.1.2-26.
