NVD Description
Note: Versions mentioned in the description apply only to the upstream libcatalyst-authentication-credential-http-perl package and not the libcatalyst-authentication-credential-http-perl package as distributed by Debian.
See How to fix? for Debian:14 relevant fixed versions and status.
Catalyst::Authentication::Credential::HTTP versions 1.018 and earlier for Perl generate nonces using the Perl Data::UUID library.
- Data::UUID does not use a strong cryptographic source for generating UUIDs.
- Data::UUID returns v3 UUIDs, which are generated from known information and are unsuitable for security, as per RFC 9562.
- The nonces should be generated from a strong cryptographic source, as per RFC 7616.
