Descriptions

The ldb_wildcard_compare function in ldb_match.c in ldb before 1.1.24, as used in the AD LDAP server in Samba 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3, mishandles certain zero values, which allows remote attackers to cause a denial of service (infinite loop) via crafted packets.

La función ldb_wildcard_compare en ldb_match.c en ldb en versiones anteriores a 1.1.24, como se utiliza en el servidor AD LDAP en Samba 4.x en versiones anteriores a 4.1.22, 4.2.x en versiones anteriores a 4.2.7 y 4.3.x en versiones anteriores a 4.3.3, no maneja correctamente valores cero, lo que permite a atacantes remotos provocar una denegación de servicio (bucle infinito) a través de paquetes manipulados.

A denial of service flaw was found in the ldb_wildcard_compare() function of libldb. A remote attacker could send a specially crafted packet that, when processed by an application using libldb (for example the AD LDAP server in Samba), would cause that application to consume an excessive amount of memory and crash.
