Descriptions

The get_user_grouplist function in the extdom plug-in in FreeIPA before 4.1.4 does not properly reallocate memory when processing user accounts, which allows remote attackers to cause a denial of service (crash) via a group list request for a user that belongs to a large number of groups.

La función get_user_grouplist en el plug-in extdom en FreeIPA en versiones anteriores a 4.1.4 no reasigna memoria correctamente cuando procesa las cuentas de usuarios, lo que permite a atacantes remotos causar denegación de servicio (caída) a través de una solicitud de lista de grupo para un usuario que pertenece a un número grande de grupos.

It was discovered that the IPA extdom Directory Server plug-in did not correctly perform memory reallocation when handling user account information. A request for a list of groups for a user that belongs to a large number of groups would cause a Directory Server to crash.
