Name of the Vulnerable Software and Affected Versions unrar versions 0.0.1

Description The issue is caused by a buffer over-read in the unrarlib.c file, related to the ExtrFile and stricomp functions. This can be exploited by a remote attacker using a specially crafted archive to bypass directory restrictions and cause a denial of service.

Recommendations For version 0.0.1, consider restricting the use of the ExtrFile and stricomp functions in unrarlib.c until a patch is available. As a temporary workaround, avoid using the unrar tool with untrusted archives to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
