Keepalive Connections Causing Denial Of Service in puma

Impact The fix for CVE-2019-16770 was incomplete. The original fix only protected existing connections that had already been accepted from having their requests starved by greedy persistent-connections saturating all threads in the same process. However, new connections may still be starved by...

Denial Of Service (DoS)

varnish cache is vulnerable to denial of service. A remote attacker is able to crash the application by sending malicious HTTP/1 requests processed on the same HTTP/1 keep-alive connection. This causes Varnish to restart with a clean cache, resulting in a denial of service condition...

varnish: denial of service handling certain crafted HTTP/1 requests

A flaw was found in the way Varnish parsed certain HTTP/1 requests. A remote attacker could use this flaw to crash Varnish by sending specially crafted multiple HTTP/1 requests processed on the same HTTP/1 keep-alive connection. This causes Varnish to restart with a clean cache, causing a denial ...
