=========================================================================Ubuntu Security Notice USN-
Apport could be made to crash or overwrite files as an administrator.

Summary

Apport could be made to crash or overwrite files as an administrator.

Software Description:

- apport: automatically generate crash reports for debugging

Details:

Halfdog discovered that Apport incorrectly handled kernel crash dump files.

A local attacker could use this issue to cause a denial of service, or

possibly elevate privileges. The default symlink protections for affected

releases should reduce the vulnerability to a denial of service.
