Summary

perl-Authen-SASL security update

Details

Authen::SASL::Perl is the pure Perl implementation of SASL mechanisms in the Authen::SASL framework, At the time of this writing it provides the client part implementation for the following SASL mechanisms.

Security Fix(es):

Authen::SASL::Perl::DIGEST_MD5 versions 2.04 through 2.1800 for Perl generates the cnonce insecurely. The cnonce (client nonce) is generated from an MD5 hash of the PID, the epoch time and the built-in rand function. The PID comes from a small set of numbers, and the epoch time may be guessed if not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage. According to RFC 2831, the cnonce-value should be provided by the client and contain at least 64 bits of entropy to ensure security.(CVE-2025-40918)
