Name of the Vulnerable Software and Affected Versions libX11 versions prior to 1.6.5

Description The issue is related to the XListExtensions function in the ListExt.c file of the libX11 library, which provides the client-side API for the X Window System. It is associated with a buffer overflow due to interpreting a variable as signed instead of unsigned, resulting in an out-of-bounds write. This could allow a remote attacker to cause a denial of service or execute arbitrary code.

Recommendations For libX11 versions prior to 1.6.5, update to version 1.6.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the XListExtensions function until a patch is available.
