modules/loaders/loader_ico.c in imlib2 1.6.0 has an integer overflow (with resultant invalid memory allocations and out-of-bounds reads) via an icon with many colors in its color map.

The remote Ubuntu 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-5099-1 advisory.

    It was discovered that Imlib2 incorrectly handled certain ICO images. An attacker could use this issue to     cause a denial of service and possibly execute arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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