Name of the Vulnerable Software and Affected Versions libsixel versions prior to 1.8.5

Description The issue is related to an invalid read in the stb image.h component of libsixel, which can be exploited by attackers to cause a denial of service (DOS) via a crafted PSD file. This can be achieved by a remote attacker.

Recommendations For versions prior to 1.8.5, update to version 1.8.5 or later to resolve the issue. As a temporary workaround, consider restricting the use of the stb image.h component until a patch is available.
