"The remote Windows host has a version of ImageMagick installed that is prior to 7.1.2-10. It is, therefore, affected
by an integer overflow vulnerability.

ImageMagick is a software suite to create, edit, compose, or convert bitmap images. In versions 7.1.2-9 and prior, the
TIM (PSX TIM) image parser contains a critical integer overflow vulnerability in its ReadTIMImage function
(coders/tim.c). The code reads width and height (16-bit values) from the file header and calculates image_size = 2 *
width * height without checking for overflow. On 32-bit systems (or where size_t is 32-bit), this calculation can
overflow if width and height are large (e.g., 65535), wrapping around to a small value. This results in a small heap
allocation via AcquireQuantumMemory and later operations relying on the dimensions can trigger an out of bounds read.
This issue is fixed in version 7.1.2-10.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
