Canonical has published in a security notice details about a xdiagnose vulnerability for its Ubuntu 12.04 LTS (Precise Pangolin) operating system.According to Canonical, third-party applications using xdiagnose could potentially have been made to overwrite files. It was 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 third-party applications which import the vulnerable code.
The security flaws can be fixed if you upgrade your system(s) to the latest xdiagnose package, specific to the operating system. To apply the update, run the Update Manager application.
In general, a standard system update is enough to make all the necessary changes. A system restart won't be necessary to implement the changes.
