USN-4099-1 nginx vulnerabilities

Jonathan Looney discovered that nginx incorrectly handled the HTTP/2 implementation. A remote attacker could possibly use this issue to consume resources, leading to a denial of service...

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...

DEBIAN-CVE-2019-9512

Some HTTP/2 implementations are vulnerable to ping floods, potentially leading to a denial of service. The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU,...

PT-2019-3018

Name of the Vulnerable Software and Affected Versions HTTP/2 implementations affected versions not specified Description The issue is related to a denial of service vulnerability in some HTTP/2 implementations. An attacker can create multiple request streams and continually shuffle the priority o...

UBUNTU-CVE-2019-9518

Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSHPROMISE. The peer spends ti...
