13 Jul 2017 — Heimdal before 7.4 allows remote attackers to impersonate services with Orpheus' Lyre attacks because it obtains service-principal names in a way that violates the Kerberos 5 protocol specification. In _krb5_extract_ticket() the KDC-REP service name must be obtained from the encrypted version stored in 'enc_part' instead of the unencrypted version stored in 'ticket'. Use of the unencrypted version provides an opportunity for successful server impersonation and other attacks. NOTE: this CVE is only for Heimd... • http://www.debian.org/security/2017/dsa-3912 • CWE-345: Insufficient Verification of Data Authenticity •

24 May 2017 — Samba since version 3.5.0 and before 4.6.4, 4.5.10 and 4.4.14 is vulnerable to remote code execution vulnerability, allowing a malicious client to upload a shared library to a writable share, and then cause the server to load and execute it. Samba desde la versión 3.5.0 y anteriores a 4.6.4, versiones 4.5.10 y 4.4.14, son vulnerables a la ejecución de código remota, lo que permite que un cliente malicioso cargar una biblioteca compartida en un recurso compartido editable, y luego causar que el servidor lo c... • https://packetstorm.news/files/id/142710 • CWE-94: Improper Control of Generation of Code ('Code Injection') •

23 Mar 2017 — Samba before versions 4.6.1, 4.5.7 and 4.4.11 are vulnerable to a malicious client using a symlink race to allow access to areas of the server file system not exported under the share definition. Samba, en versiones anteriores a 4.6.1, 4.5.7 y 4.4.11, es vulnerable a un cliente malicioso que emplee una carrera symlink para permitir el acceso a áreas del sistema de archivos del servidor que no se exportan bajo la definición compartida.

19 Dec 2016 — A flaw was found in samba versions 4.0.0 to 4.5.2. The Samba routine ndr_pull_dnsp_name contains an integer wrap problem, leading to an attacker-controlled memory overwrite. ndr_pull_dnsp_name parses data from the Samba Active Directory ldb database. Any user who can write to the dnsRecord attribute over LDAP can trigger this memory corruption. By default, all authenticated LDAP users can write to the dnsRecord attribute on new DNS objects. This makes the defect a remote privilege escalation. • http://www.securityfocus.com/bid/94970 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •

19 Dec 2016 — Samba version 4.0.0 up to 4.5.2 is vulnerable to privilege elevation due to incorrect handling of the PAC (Privilege Attribute Certificate) checksum. A remote, authenticated, attacker can cause the winbindd process to crash using a legitimate Kerberos ticket. A local service with access to the winbindd privileged pipe can cause winbindd to cache elevated access permissions. Samba versiones 4.0.0 hasta 4.5.2, es vulnerable a la elevación de privilegios debido al manejo incorrecto de la suma de comprobación P... • http://rhn.redhat.com/errata/RHSA-2017-0494.html • CWE-264: Permissions, Privileges, and Access Controls •

19 Dec 2016 — It was found that Samba before versions 4.5.3, 4.4.8, 4.3.13 always requested forwardable tickets when using Kerberos authentication. A service to which Samba authenticated using Kerberos could subsequently use the ticket to impersonate Samba to other services or domain users. Se ha descubierto que Samba, en versiones anteriores a la 4.5.3, 4.4.8 y 4.3.13, siempre solicitaba tickets que podían reenviarse al emplear la autenticación de Kerberos.
