  - 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. (CVE-2025-66628)

Note that Nessus relies on the presence of the package as reported by the vendor.");
