NVD description
ImageMagick is free and open-source software used for editing and manipulating digital images. `WriteUHDRImage` in `coders/uhdr.c` uses `int` arithmetic to compute the pixel buffer size. Prior to version 7.1.2-15, when image dimensions are large, the multiplication overflows 32-bit `int`, causing an undersized heap allocation followed by an out-of-bounds write. This can crash the process or potentially lead to an out of bounds heap write. Version 7.1.2-15 contains a patch.

CVE-2026-25794 Integer Overflow in ImageMagick WriteUHDRImage Leading to Heap Corruption https://vulmon.com/vulnerabilitydetails?qid=CVE-2026-25794
Post summary
The text announces CVE-2026-25794, an integer overflow in ImageMagick's WriteUHDRImage that can cause heap corruption, with no additional details on PoC, exploitation, or patches.
CVE-2026-25794 pertains to a critical flaw in ImageMagick, an open-source image processing software widely used for editing and manipulating digital images. The vulnerability resides in the `WriteUHDRImage` function within the `coders/uhdr.c` source file. Specifically, the function uses 32-bit integer arithmetic to calculate the size of the pixel buffer needed for image processing. When handling images with very large dimensions, this calculation can overflow, resulting in an undersized heap allocation. Subsequently, the program writes beyond the allocated buffer bounds, leading to an out-of-bounds heap write. This flaw can cause application crashes or potentially enable remote code execution. #Cybersecurity #CVE #HighSeverity #SecurityAlert #RemoteCodeExecution #DDoS https://cvetodo.com/cve/CVE-2026-25794
