<br><dt>More information:</dt>
<dd>Several issues have been identified in Samba, the SMB/CIFS file- and <br>
print-server implementation for GNU/Linux. <br>
<br>
CVE-2007-2444 <br>
<br>
When translating SIDs to/from names using Samba local list of user and group <br>
accounts, a logic error in the smbd daemon's internal security stack may result <br>
in a transition to the root user id rather than the non-root user. The user is <br>
then able to temporarily issue SMB/CIFS protocol operations as the root user. <br>
This window of opportunity may allow the attacker to establish addition means <br>
of gaining root access to the server. <br>
<br>
CVE-2007-2446 <br>
<br>
Various bugs in Samba's NDR parsing can allow a user to send specially crafted <br>
MS-RPC requests that will overwrite the heap space with user defined data. <br>
<br>
CVE-2007-2447 <br>
<br>
Unescaped user input parameters are passed as arguments to /bin/sh allowing for <br>
remote command execution. <br>
</dd>
<br><dt>For the testing distribution (lenny) this is fixed in version 3.0.24-6+lenny3</dt>
<dt>For the unstable distribution (sid) this is fixed in version 3.0.25-1</dt>
<br><dt>This upgrade is strongly recommended if you use samba.<dt>
<br><dt>If you have the secure testing lines in your sources.list, you can update by running this command as root:</dt>
<dd>apt-get update && apt-get upgrade</dd>
<br>
<br>
<dt>To use the Debian testing security archive, add the following lines to your /etc/apt/sources.list:<dt>
<br>
<dd>deb http://security.debian.org/ testing/updates main contrib non-free</dd>
<dd>deb-src http://security.debian.org/ testing/updates main contrib non-free</dd>
