========================================================================== Ubuntu Security Notice USN-1802-1 April 16, 2013
A security issue affects these releases of Ubuntu and its derivatives:
Samba would allow unintended write access to files over the network.
Software Description: - samba: SMB/CIFS file, print, and login server for Unix
It was discovered that Samba incorrectly handled CIFS share attributes when SMB2 was used. A remote authenticated user could possibly gain write access to certain shares, bypassing the intended permissions.
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04 LTS: samba 2:3.6.3-2ubuntu2.6
In general, a standard system update will make all the necessary changes.
