CVE-2013-7041
The pam_userdb module for Pam uses a case-insensitive method to compare hashed passwords, which makes it easier for attackers to guess the password via a brute force attack.
Does this matter?
Lower severity and a low EPSS score (2.48%). Track it; it rarely justifies an emergency change on its own.
