AI Analysis
Technical Summary
CVE-2024-10963 is a vulnerability in the pam_access module of PAM where improper hostname interpretation can lead to an access control bypass. PAM is a system used to configure authentication policies without recompiling programs. This flaw could allow unauthorized access by bypassing hostname-based access controls. Red Hat has issued an important security advisory (RHSA-2024:10244) and released updated pam packages for Red Hat Enterprise Linux 9 and its extended support variants to fix this issue.
Potential Impact
The vulnerability allows an attacker to bypass access control restrictions based on hostname checks in PAM, potentially granting unauthorized access to systems relying on pam_access for authentication policies. This could compromise system security by allowing unauthorized users to authenticate where they should be denied.
Mitigation Recommendations
Red Hat has released an official security update for pam version 1.5.1-22.el9_5 that addresses this vulnerability. Users of Red Hat Enterprise Linux 9 and its extended update support versions should apply this update promptly.
