GHSA-Q4HG-RMQ2-52Q9 Improper Locking in Apache Tomcat

The fix for CVE-2019-0199 was incomplete and did not address HTTP/2 connection window exhaustion on write in Apache Tomcat versions 9.0.0.M1 to 9.0.19 and 8.5.0 to 8.5.40 . By not sending WINDOWUPDATE messages for the connection window stream 0 clients were able to cause server-side threads to...

DEBIAN-CVE-2019-0197

A vulnerability was found in Apache HTTP Server 2.4.34 to 2.4.38. When HTTP/2 was enabled for a http: host or H2Upgrade was enabled for h2 on a https: host, an Upgrade request from http/1.1 to http/2 that was not the first request on a connection could lead to a misconfiguration and crash. Server...

istio/envoy: Authorization bypass via null characters injection in HTTP/1.x

A flaw was found in Envoy version 1.9.0 and older, where Envoy does not reject embedded zero characters NUL, ASCII 0x0 when processing HTTP/1.x header values. This flaw allows remote attackers crafting header values containing embedded NUL characters to potentially bypass header matching rules,...

UBUNTU-CVE-2019-0199

The HTTP/2 implementation in Apache Tomcat 9.0.0.M1 to 9.0.14 and 8.5.0 to 8.5.37 accepted streams with excessive numbers of SETTINGS frames and also permitted clients to keep streams open without reading/writing request/response data. By keeping streams open for requests that utilised the Servle...

haproxy: Mishandling of priority flag in short HEADERS frame by HTTP/2 decoder allows for crash

A flaw was found in HAProxy, versions before 1.8.17 and 1.9.1. Mishandling occurs when a priority flag is set on too short HEADERS frame in the HTTP/2 decoder, allowing an out-of-bounds read and a subsequent crash to occur. A remote attacker can exploit this flaw to cause a denial of service. Tho...

httpd: DoS for HTTP/2 connections by continuous SETTINGS frames

In Apache HTTP Server 2.4.17 to 2.4.34, by sending continuous, large SETTINGS frames a client can occupy a connection, server thread and CPU time without any connection timeout coming to effect. This affects only HTTP/2 connections. A possible mitigation is to not enable the h2 protocol...

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...

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...

UBUNTU-CVE-2018-17189

In Apache HTTP server versions 2.4.37 and prior, by sending request bodies in a slow loris way to plain resources, the h2 stream for that request unnecessarily occupied a server thread cleaning up that incoming data. This affects only HTTP/2 modhttp2 connections...

UBUNTU-CVE-2018-6335

A Malformed h2 frame can cause 'std::outofrange' exception when parsing priority meta data. This behavior can lead to denial-of-service. This affects all supported versions of HHVM 3.25.2, 3.24.6, and 3.21.10 and below when using the proxygen server to handle HTTP2 requests...

nginx: Excessive memory consumption via flaw in HTTP/2 implementation

nginx before versions 1.15.6 and 1.14.1 has a vulnerability in the implementation of HTTP/2 that can allow for excessive memory consumption.
