Summary
pam security update
Details

PAM (Pluggable Authentication Modules) is a system of libraries that handle the authentication tasks of applications (services) on the system.

Security Fix(es):

A vulnerability was found in Linux-PAM up to 1.7.0 and classified as critical.Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.Impacted is confidentiality, integrity, and availability.Upgrading to version 1.7.1 eliminates this vulnerability.(CVE-2025-6020)

Severity
7.8 (High)
