Descriptions

A vulnerability was found in pam_access due to the improper handling of tokens in access.conf, interpreted as hostnames. This flaw allows attackers to bypass access restrictions by spoofing hostnames, undermining configurations designed to limit access to specific TTYs or services. The flaw poses a risk in environments relying on these configurations for local access control.

A flaw was found in pam_access, where certain rules in its configuration file are mistakenly treated as hostnames. This vulnerability allows attackers to trick the system by pretending to be a trusted hostname, gaining unauthorized access. This issue poses a risk for systems that rely on this feature to control who can access certain services or terminals.
