Eclipse Jetty affected by MadeYouReset HTTP/2 vulnerability
Technical Details Below is a technical explanation of a newly discovered vulnerability in HTTP/2, which we refer to as “MadeYouReset.” MadeYouReset Vulnerability Summary The MadeYouReset DDoS vulnerability is a logical vulnerability in the HTTP/2 protocol, that uses malformed HTTP/2 control frame...
mod_http2: reset requests exhaust memory (incomplete fix of CVE-2023-44487)
A flaw was found in modhttp2. When a HTTP/2 stream is reset RST frame by a client, there is a time window were the request's memory resources were not reclaimed immediately. Instead, de-allocation was deferred to connection close. A client could send new requests and resets, keeping the connectio...
GHSA-8R5V-VM4M-4G25 Resource exhaustion vulnerability in h2 may lead to Denial of Service (DoS)
An attacker with an HTTP/2 connection to an affected endpoint can send a steady stream of invalid frames to force the generation of reset frames on the victim endpoint. By closing their recv window, the attacker could then force these resets to be queued in an unbounded fashion, resulting in Out ...
HTTP/2: Multiple HTTP/2 enabled web servers are vulnerable to a DDoS attack (Rapid Reset Attack)
A flaw was found in handling multiplexed streams in the HTTP/2 protocol. A client can repeatedly make a request for a new multiplex stream and immediately send an RSTSTREAM frame to cancel it. This creates extra work for the server setting up and tearing down the streams while not hitting any...
PT-2023-6292
Name of the Vulnerable Software and Affected Versions Apache HTTP Server versions prior to 2.4.58 Description The issue is related to the handling of HTTP/2 streams in the Apache HTTP Server. When a client resets an HTTP/2 stream using an RST frame, there is a time window where the request's memo...
HTTP/2: flood using HEADERS frames results in unbounded memory growth
A flaw was found in HTTP/2. Using HEADER frames with invalid HTTP headers and queuing of response RSTSTREAM frames, an attacker could cause a flood resulting in unbounded memory growth. The highest threat from this vulnerability is to system availability...
