Name of the Vulnerable Software and Affected Versions radare2 versions prior to 3.1.4

Description The issue allows attackers to cause a denial-of-service, resulting in an application crash, by crafting a specific arm assembly input. This is due to a loop using an incorrect index and missing length validation in certain files.

Recommendations For versions prior to 3.1.4, update to version 3.1.4 or later to resolve the issue. As a temporary workaround, consider restricting the use of the assemble function until a patch is available.
