USN-1802-1: Samba vulnerability

16 April 2013

Samba would allow unintended write access to files over the network.



  • 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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 12.04

In general, a standard system update will make all the necessary changes.
