https://notcve.org/view.php?id=CVE-2015-0240
The Netlogon server implementation in smbd in Samba 3.5.x and 3.6.x before 3.6.25, 4.0.x before 4.0.25, 4.1.x before 4.1.17, and 4.2.x before 4.2.0rc5 performs a free operation on an uninitialized stack pointer, which allows remote attackers to execute arbitrary code via crafted Netlogon packets that use the ServerPasswordSet RPC API, as demonstrated by packets reaching the _netr_ServerPasswordSet function in rpc_server/netlogon/srv_netlog_nt.c. La implentación del servidor Netlogon en smbd en Samba 3.5.x y 3.6.x anterior a 3.6.25, 4.0.x anterior a 4.0.25, 4.1.x anterior a 4.1.17, y 4.2.x anterior a 4.2.0rc5 realiza una operación libre sobre un puntero de pila no inicializado, lo que permite a atacantes remotos ejecutar código arbitrario a través de paquetes Netlogon manipulados que utilizan la API RPC ServerPasswordSet, tal y como fue demostrado mediante paquetes alcanzando la función _netr_ServerPasswordSet en rpc_server/netlogon/srv_netlog_nt.c. An uninitialized pointer use flaw was found in the Samba daemon (smbd). A malicious Samba client could send specially crafted netlogon packets that, when processed by smbd, could potentially lead to arbitrary code execution with the privileges of the user running smbd (by default, the root user). • https://www.exploit-db.com/exploits/36741 http://advisories.mageia.org/MGASA-2015-0084.html http://lists.opensuse.org/opensuse-security-announce/2015-02/msg00028.html http://lists.opensuse.org/opensuse-security-announce/2015-02/msg00030.html http://lists.opensuse.org/opensuse-security-announce/2015-02/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2015-02/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00042.html http://lists.opensuse.org/opensuse- • CWE-17: DEPRECATED: Code CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Samba 4.0.x before 4.0.24, 4.1.x before 4.1.16, and 4.2.x before 4.2rc4, when an Active Directory Domain Controller (AD DC) is configured, allows remote authenticated users to set the LDB userAccountControl UF_SERVER_TRUST_ACCOUNT bit, and consequently gain privileges, by leveraging delegation of authority for user-account or computer-account creation. Samba 4.0.x anterior a 4.0.24, 4.1.x anterior a 4.1.16, y 4.2.x anterior a 4.2rc4, cuando un Active Directory Domain Controller (AD DC) está configurado, permite a usuarios remotos autenticados configurar el bit de LDB userAccountControl UF_SERVER_TRUST_ACCOUNT, y como consecuencia ganar privilegios, mediante el aprovechamiento de la delegación de autoridad para la creación de cuentas de usuarios o cuentas de ordenadores. • http://lists.opensuse.org/opensuse-security-announce/2015-02/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00042.html http://secunia.com/advisories/62594 http://www.securityfocus.com/bid/72278 http://www.securitytracker.com/id/1031615 http://www.slackware.com/security/viewer.php?l=slackware-security&y=2015&m=slackware-security.416326 http://www.ubuntu.com/usn/USN-2481-1 https://download.samba.org/pub/samba/patches/security/samba-4.0.23-CVE-2014-8143.p • CWE-264: Permissions, Privileges, and Access Controls •

NetBIOS name services daemon (nmbd) in Samba 4.0.x before 4.0.21 and 4.1.x before 4.1.11 allows remote attackers to execute arbitrary code via unspecified vectors that modify heap memory, involving a sizeof operation on an incorrect variable in the unstrcpy macro in string_wrappers.h. NetBIOS name services daemon (nmbd) en Samba 4.0.x anterior a 4.0.21 y 4.1.x anterior a 4.1.11 permite a atacantes remotos ejecutar código arbitrario a través de vectores no especificados que modifican la memoria dinámica, involucrando una operación sizeof sobre una variable incorrecta en la macro unstrcpy en string_wrappers.h. A heap-based buffer overflow flaw was found in Samba's NetBIOS message block daemon (nmbd). An attacker on the local network could use this flaw to send specially crafted packets that, when processed by nmbd, could possibly lead to arbitrary code execution with root privileges. • http://lists.fedoraproject.org/pipermail/package-announce/2014-August/136280.html http://lists.fedoraproject.org/pipermail/package-announce/2014-August/136864.html http://lists.opensuse.org/opensuse-updates/2014-08/msg00027.html http://secunia.com/advisories/59583 http://secunia.com/advisories/59610 http://secunia.com/advisories/59976 http://www.samba.org/samba/security/CVE-2014-3560 http://www.securityfocus.com/bid/69021 http://www.securitytracker.com/id/1030663 http://www.ubuntu.com&#x • CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

The sys_recvfrom function in nmbd in Samba 3.6.x before 3.6.24, 4.0.x before 4.0.19, and 4.1.x before 4.1.9 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a malformed UDP packet. La función sys_recvfrom en nmbd en Samba 3.6.x anterior a 3.6.24, 4.0.x anterior a 4.0.19 y 4.1.x anterior a 4.1.9 permite a atacantes remotos causar una denegación de servicio (bucle infinito y consumo de CPU) a través de un paquete UDP malformado. A denial of service flaw was found in the way the sys_recvfile() function of nmbd, the NetBIOS message block daemon, processed non-blocking sockets. An attacker could send a specially crafted packet that, when processed, would cause nmbd to enter an infinite loop and consume an excessive amount of CPU time. • http://advisories.mageia.org/MGASA-2014-0279.html http://linux.oracle.com/errata/ELSA-2014-0866.html http://lists.fedoraproject.org/pipermail/package-announce/2014-August/136864.html http://lists.fedoraproject.org/pipermail/package-announce/2014-June/134717.html http://rhn.redhat.com/errata/RHSA-2014-0866.html http://secunia.com/advisories/59378 http://secunia.com/advisories/59407 http://secunia.com/advisories/59433 http://secunia.com/advisories/59579 http://secunia.com/advisories/598 • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2014-3493
The push_ascii function in smbd in Samba 3.6.x before 3.6.24, 4.0.x before 4.0.19, and 4.1.x before 4.1.9 allows remote authenticated users to cause a denial of service (memory corruption and daemon crash) via an attempt to read a Unicode pathname without specifying use of Unicode, leading to a character-set conversion failure that triggers an invalid pointer dereference. La función push_ascii en smbd en Samba 3.6.x anterior a 3.6.24, 4.0.x anterior a 4.0.19 y 4.1.x anterior a 4.1.9 permite a usuarios remotos autenticados causar una denegación de servicio (corrupción de memoria y caída de demonio) a través de in intento de leer un nombre de ruta Unicode sin especificar el uso de Unicode, que conduce a un fallo de conversión de configuración de carácter que provoca una referencia a puntero inválida. It was discovered that smbd, the Samba file server daemon, did not properly handle certain files that were stored on the disk and used a valid Unicode character in the file name. An attacker able to send an authenticated non-Unicode request that attempted to read such a file could cause smbd to crash. • http://advisories.mageia.org/MGASA-2014-0279.html http://linux.oracle.com/errata/ELSA-2014-0866.html http://lists.fedoraproject.org/pipermail/package-announce/2014-August/136864.html http://lists.fedoraproject.org/pipermail/package-announce/2014-June/134717.html http://rhn.redhat.com/errata/RHSA-2014-0866.html http://secunia.com/advisories/59378 http://secunia.com/advisories/59407 http://secunia.com/advisories/59433 http://secunia.com/advisories/59579 http://secunia.com/advisories/598 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-393: Return of Wrong Status Code •
