How to fix?

Upgrade SLES:16.0.0 pam-extra to version 1.7.1-160000.5.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream pam-extra package and not the pam-extra package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

Linux-PAM through 1.7.2 contains an observable timing discrepancy (CWE-208) in the pam_userdb module's plaintext-password comparison path in modules/pam_userdb/pam_userdb.c that allows a local or network-adjacent attacker able to repeatedly drive authentication through a calling service to recover the plaintext password of a target account by measuring response-timing differences.
