Name of the Vulnerable Software and Affected Versions Liblisp versions through commit 4c65969

Description The issue is related to an out-of-bounds-read vulnerability in the get length function, which is located in the eval.c file and operates on lisp cell t objects. This vulnerability can be exploited due to the lack of proper bounds checking in the get length function.

Recommendations For versions through commit 4c65969, consider applying a patch or modification to the get length function to include proper bounds checking to prevent out-of-bounds reads. As a temporary workaround, consider implementing additional validation or error handling for the lisp cell t objects passed to the get length function until a patch is available.
