Name of the Vulnerable Software and Affected Versions Debian-edu-config versions prior to 2.11.10 debian-lan-config versions prior to 0.26

Description The issue is related to a security flaw in privilege management. Exploitation of this flaw can allow an attacker to gain unauthorized access to confidential data, cause a denial of service, and impact data integrity. The problem arises from overly permissive ACLs configured for the Kerberos admin server, which permits password changes for other Kerberos user principals.

Recommendations For Debian-edu-config versions prior to 2.11.10, update to version 2.11.10 or later. For debian-lan-config versions prior to 0.26, update to version 0.26 or later.
