Descriptions
smbd in Samba 3.0 before 3.0.37, 3.2 before 3.2.15, 3.3 before 3.3.8, and 3.4 before 3.4.2 allows remote authenticated users to cause a denial of service (infinite loop) via an unanticipated oplock break notification reply packet.
smbd en Samba v3.0 anterior a v3.0.37, v3.2 anterior a v3.2.15, v3.3 anterior a v3.3.8 y v3.4 anterior a v3.4.2, permite a usuarios autenticados remotamente provocar una denegación de servicio (bucle infinito) a través de un paquete de notificación de respuesta "oplock break" imprevisto.
J. David Hester discovered that Samba incorrectly handled users that lack home directories when the automated [homes] share is enabled. An authenticated user could connect to that share name and gain access to the whole filesystem. Tim Prouty discovered that the smbd daemon in Samba incorrectly handled certain unexpected network replies. A remote attacker could send malicious replies to the server and cause smbd to use all available CPU, leading to a denial of service. Ronald Volgers discovered that the mount.cifs utility, when installed as a setuid program, would not verify user permissions before opening a credentials file. A local user could exploit this to use or read the contents of unauthorized credential files. Reinhard discovered that the smbclient utility contained format string vulnerabilities in its file name handling. Because of security features in Ubuntu, exploitation of this vulnerability is limited. If a user or automated system were tricked into processing a specially crafted file name, smbclient could be made to crash, possibly leading to a denial of service. This only affected Ubuntu 8.10. Jeremy Allison discovered that the smbd daemon in Samba incorrectly handled permissions to modify access control lists when dos filemode is enabled. A remote attacker could exploit this to modify access control lists. This only affected Ubuntu 8.10 and Ubuntu 9.04.
