Name of the Vulnerable Software and Affected Versions CryptX versions prior to 0.062

Description The issue concerns the CryptX module for Perl, where the functions gcm decrypt verify() and chacha20poly1305 decrypt verify() do not verify the tag, potentially leading to security issues.

Recommendations For versions prior to 0.062, update to version 0.062 or later to resolve the issue. As a temporary workaround, consider disabling the use of gcm decrypt verify() and chacha20poly1305 decrypt verify() functions until a patch is available. Restrict access to the CryptX module to minimize the risk of exploitation.
