Name of the Vulnerable Software and Affected Versions Crypt::Password versions prior to 0.29

Description Crypt::Password for Perl is susceptible to timing attacks. The check password() function uses the built-in eq operator, which allows discrepancies in timing to be used to guess the underlying hash.

Recommendations Update Crypt::Password to version 0.29 or later. As a temporary workaround, restrict access to the check password() function to minimize the risk of exploitation.
