HTTP/2: flood using PING frames results in unbounded memory growth

A flaw was found in HTTP/2. Using PING frames and queuing of response PING ACK frames, a flood attack could occur resulting in unbounded memory growth. The highest threat from this vulnerability is to system availability...

The vulnerability of the HTTP/2 web server protocol of the Apache Traffic Server, a Node.js-based software platform, stems from a lack of resource consumption control mechanisms. This allows attackers to trigger service interruptions.

The vulnerability of the HTTP/2 web server protocol of the Apache Traffic Server, a Node.js-based software platform, is related to errors in the resource consumption control mechanism. Exploiting this vulnerability can allow an attacker to cause service interruptions through a specially crafted...

Mozilla: Use-after-free with HTTP/2 cached stream

A use-after-free vulnerability can occur in HTTP/2 when a cached HTTP/2 stream is closed while still in use, resulting in a potentially exploitable crash. This vulnerability affects Firefox ESR 60.8, Firefox 68, and Thunderbird 60.8...

httpd: mod_http2: Too much time allocated to workers, possibly leading to DoS

By specially crafting HTTP/2 requests, workers would be allocated 60 seconds longer than necessary, leading to worker exhaustion and a denial of service. Fixed in Apache HTTP Server 2.4.34 Affected 2.4.18-2.4.30,2.4.33...

httpd: Use-after-free on HTTP/2 stream shutdown

When an HTTP/2 stream was destroyed after being handled, the Apache HTTP Server prior to version 2.4.30 could have written a NULL pointer potentially to an already freed memory. The memory pools maintained by the server make this vulnerability hard to trigger in usual configurations, the reporter...
