Ubuntu Security Notice USN-1591-1
2nd October, 2012
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
3rd party applications using xdiagnose could potentially be made to overwrite files.
- xdiagnose - X.org diagnosis tool
Alec Warner discovered that xdiagnose improperly handled temporary files
in welcome.py when creating user-initiated archive files. While failsafeX
does not use the vulnerable code, this update removes this functionality to
protect any 3rd party applications which import the vulnerable code. In the
default Ubuntu installation, this should be prevented by the Yama link
The problem can be corrected by updating your system to the following package version:
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.
