VectorAV:N/AC:L/Au:N/C:P/I:N/A:C
Name of the Vulnerable Software and Affected Versions ImageMagick versions prior to 7.1.2-15
Description ImageMagick is software used for editing and manipulating digital images. The WriteUHDRImage function in coders/uhdr.c uses 32-bit integer arithmetic to calculate the pixel buffer size. When image dimensions are large, this calculation can overflow, resulting in an undersized heap allocation and an out-of-bounds write. This can crash the process or potentially lead to an out-of-bounds heap write. The vulnerable function is WriteUHDRImage.
Recommendations Update to ImageMagick version 7.1.2-15 or later.
