Ubuntu Security Notice (C) 2009-2015 Canonical, Inc. / NASL script (C) 2009-2015 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related patches.
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. (CVE-2009-2813)
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. (CVE-2009-2906)
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. (CVE-2009-2948)
Reinhard NiÃźl 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.
Update the affected packages.
