Doc Text:
A flaw was found in ImageMagick, a software suite for editing and manipulating digital images. An integer overflow vulnerability exists in the XWD (X Windows) encoder when processing extremely large images. This flaw can lead to an undersized memory allocation, resulting in an out-of-bounds write to the heap. A local attacker could exploit this to cause a denial of service (DoS) or potentially impact data integrity.

Description OSIDB Bzimport 2026-03-09 22:01:58 UTC
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, a 32-bit unsigned integer overflow in the XWD (X Windows) encoder can cause an undersized heap buffer allocation. When writing a extremely large image an out of bounds heap write can occur. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41.
