Echo: libauthen-sasl-perl: security update to 2.1700-1+e1

medium Tenable Self-Hosted Container Security Plugin ID 478279

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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 will come from a small set of numbers, and the epoch time may be guessed, if it is not
 leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage.
 According to RFC 2831, The cnonce-value is an opaque quoted string value provided by the client and used
 by both client and server to avoid chosen plaintext attacks, and to provide mutual authentication. The
 security of the implementation depends on a good choice. It is RECOMMENDED that it contain at least 64
 bits of entropy. (CVE-2025-40918)

Solution

Update the libauthen-sasl-perl library and its related packages to version 2.1700-1+e1 or later.
