CVE-2015-5330 – libldb: remote memory read in the Samba LDAP server

https://notcve.org/view.php?id=CVE-2015-5330

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 string lengths, which allows remote attackers to obtain sensitive information from daemon heap memory by sending crafted packets and then reading (1) an error message or (2) a database value. 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 longitudes de cadena, lo que permite a atacantes remotos obtener información sensible de la memoria dinámica del demonio enviando paquetes manipulados y después leyendo (1) un mensaje de error o (2) un valor de base de datos. A memory-read flaw was found in the way the libldb library processed LDB DN records with a null byte. An authenticated, remote attacker could use this flaw to read heap-memory pages from the server. • http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00033.html http://lists.opensuse.org/opensuse-security-announce/2016-01/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2016-01/msg00017.html http://lists.opensuse.org/opensuse-security-announce/2016-04 • CWE-135: Incorrect Calculation of Multi-Byte String Length CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
