USN-1802-1: Samba vulnerability
16 April 2013
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
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.
The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
