To be more accurate,the bugs reported to the forum are in regards to stability and other non-security related.
The bugs that CIA reports are old and need additional work to make them usable.Many antivirus firms dismissed the bugs by saying they were fixed long ago and the vulnerability was found in AVG not in avast and vlk already mentioned that it is not something that is major and would need additional work to get around AVG.But that wouldn’t be a issue considering the current state of AVG operations.
