Name of the Vulnerable Software and Affected Versions unrar-free version 0.0.1

Description The issue might allow remote attackers to cause a denial of service, resulting in a stack-based buffer overflow and application crash, or possibly have other unspecified impacts. This can occur when the DEBUG LOG mode is enabled and the software processes an RAR archive containing a long filename.

Recommendations For version 0.0.1, consider disabling the DEBUG LOG mode to minimize the risk of exploitation until a patch is available. Restrict access to RAR archives from untrusted sources to reduce the likelihood of encountering a malicious archive with a long filename.
