Descripción |
|
|
Se ha encontrado una vulnerabilidad de tipo condición de carrera en nss_ldap. La vulnerabilidad reside al no manipular de forma correcta la conexión LDAP cuando es utilizado en aplicaciones que utilizan pthread y fork después de llamar a nss_ldap. Un atacante remoto podría manipular ciertos datos y provocar que nss_ldap devuelva datos de usuario a algún otro proceso. |
