August 2019 Security Releases

August 2019 Security Releases Node.js, as well as many other implementations of HTTP/2, have been found vulnerable to Denial of Service attacks. See https://github.com/Netflix/security-bulletins/blob/master/advisories/third-party/2019-002.md for more information. Updates are now available for all...

ALPINE-CVE-2019-9517

Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write many of the byt...

HTTP/2 implementations do not robustly handle abnormal traffic and resource exhaustion

Overview Multiple HTTP/2 implementations are vulnerable to a variety of denial-of-service DoS attacks. Description The Security Considerations section of RFC7540 discusses some of the considerations needed for HTTP/2 connections as they demand more resources to operate than HTTP/1.1 connections...

GHSA-45XM-V8GQ-7JQX Excessive memory allocation

In version from 3.0.0 to 3.5.3 of Eclipse Vert.x, the WebSocket HTTP upgrade implementation buffers the full http request before doing the handshake, holding the entire request body in memory. There should be a reasonnable limit 8192 bytes above which the WebSocket gets an HTTP response with the...

UBUNTU-CVE-2016-5261

Integer overflow in the WebSocketChannel class in the WebSockets subsystem in Mozilla Firefox before 48.0 and Firefox ESR 45.4 allows remote attackers to execute arbitrary code or cause a denial of service memory corruption via crafted packets that trigger incorrect buffer-resize operations durin...

Integer overflow in WebSockets during data buffering — Mozilla

Security researcher Samuel Groß reported an integer overflow error in WebSockets during data buffering on incoming packets when an allocated buffer is resized incorrectly. This results in the buffer array holding the data being shrunk, instead of grown, resulting in attacker controlled data being...
