#23113: Manage DNS state better when "All nameservers have failed"
-------------------------------+------------------------------------
Reporter: teor | Owner:
Type: defect | Status: new
Priority: Medium | Milestone: Tor: 0.3.2.x-final
Component: Core Tor/Tor | Version: Tor: 0.2.6.10
Severity: Normal | Resolution:
Keywords: dns, security-low | Actual Points:
Parent ID: | Points: 1
Reviewer: | Sponsor:
-------------------------------+------------------------------------
Changes (by teor):
* keywords: dns => dns, security-low
Comment:
There's potentially an attack here, too:
* launch an invalid request to make tor think the primary name server is
down
* launch a valid request to a secondary name server
I don't think this gets you much, but we should think about it some more.
