Amazon Linux 2 : perl-Crypt-PasswdMD5, --advisory ALAS2-2026-3343 (ALAS-2026-3343)

high Nessus Plugin ID 319861

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of perl-Crypt-PasswdMD5 installed on the remote host is prior to 1.3-17. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-3343 advisory.

Crypt::PasswdMD5 versions through 1.42 for Perl generates insecure random values for salts.

The built-in rand function is predictable, and unsuitable for cryptography. (CVE-2026-6659)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update perl-Crypt-PasswdMD5' or or 'yum update --advisory ALAS2-2026-3343' to update your system.
