The remote Ubuntu host is missing one or more security-related
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 Nissl 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.
Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
Update the affected packages.
