Debian DLA-156-1 : samba security update

critical Nessus Plugin ID 82139

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Richard van Eeden of Microsoft Vulnerability Research discovered that Samba, a SMB/CIFS file, print, and login server for Unix, contains a flaw in the netlogon server code which allows remote code execution with root privileges from an unauthenticated connection.

For the oldstable distribution (squeeze), this problem has been fixed in version 2:3.5.6~dfsg-3squeeze12.

For the stable distribution (wheezy), this problem has been fixed in version 2:3.6.6-6+deb7u5.

We recommend that you upgrade your samba packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
