[StoatWblr (stoatwblr)]

NOT fixed: The only version available for vivid is still 2.10.9 - and has a information leak hole in it.

This needs to be backported to vivid.

[StoatWblr (stoatwblr)]

Closure disputed: This has NOT been fixed on Vivid and Wily is not officially released.
Why is Canonical allowing an known security hole to remain unfixed?
