| Description: | Description:
The remote host is missing an update to samba
announced via advisory USN-460-1.
A security issue affects the following Ubuntu releases:
Ubuntu 6.06 LTS
Ubuntu 6.10
Ubuntu 7.04
This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.
Details follow:
Paul Griffith and Andrew Hogue discovered that Samba did not fully drop
root privileges while translating SIDs. A remote authenticated user
could issue SMB operations during a small window of opportunity and gain
root privileges. (CVE-2007-2444)
Brian Schafer discovered that Samba did not handle NDR parsing
correctly. A remote attacker could send specially crafted MS-RPC
requests that could overwrite heap memory and execute arbitrary code.
(CVE-2007-2446)
It was discovered that Samba did not correctly escape input parameters
for external scripts defined in smb.conf. Remote authenticated users
could send specially crafted MS-RPC requests and execute arbitrary shell
commands. (CVE-2007-2447)
Solution:
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 6.06 LTS:
samba 3.0.22-1ubuntu3.3
Ubuntu 6.10:
samba 3.0.22-1ubuntu4.2
Ubuntu 7.04:
samba 3.0.24-2ubuntu1.1
In general, a standard system upgrade is sufficient to effect the
necessary changes.
