| Description: | Description:
The remote host is missing an update to samba
announced via advisory USN-617-1.
A security issue affects the following Ubuntu releases:
Ubuntu 6.06 LTS
Ubuntu 7.04
Ubuntu 7.10
Ubuntu 8.04 LTS
This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.
Details follow:
Samba developers discovered that nmbd could be made to overrun
a buffer during the processing of GETDC logon server requests.
When samba is configured as a Primary or Backup Domain Controller,
a remote attacker could send malicious logon requests and possibly
cause a denial of service. (CVE-2007-4572)
Alin Rad Pop of Secunia Research discovered that Samba did not
properly perform bounds checking when parsing SMB replies. A remote
attacker could send crafted SMB packets and execute arbitrary code.
(CVE-2008-1105)
Solution:
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 6.06 LTS:
libsmbclient 3.0.22-1ubuntu3.7
samba 3.0.22-1ubuntu3.7
Ubuntu 7.04:
libsmbclient 3.0.24-2ubuntu1.6
samba 3.0.24-2ubuntu1.6
Ubuntu 7.10:
libsmbclient 3.0.26a-1ubuntu2.4
samba 3.0.26a-1ubuntu2.4
Ubuntu 8.04 LTS:
libsmbclient 3.0.28a-1ubuntu4.2
samba 3.0.28a-1ubuntu4.2
In general, a standard system upgrade is sufficient to effect the
necessary changes.
