HTTP/2: large amount of data requests leads to denial of service

A flaw was found in HTTP/2. An attacker can request a large amount of data by manipulating window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this queue can consume excess CPU, memory, or both, leading to a...

ALPINE-CVE-2019-9514

Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RSTSTREAM frames from the peer. Depending on how the peer queues the...

UBUNTU-CVE-2019-9516

Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory fo...

nginx: Excessive CPU usage 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 CPU usage. This issue affects nginx compiled with the ngxhttpv2module not compiled by default if the 'http2' option of the 'listen' directive is used in a configuration file...

UBUNTU-CVE-2015-5206

Unspecified vulnerability in the HTTP/2 experimental feature in Apache Traffic Server before 5.3.x before 5.3.2 has unknown impact and attack vectors, a different vulnerability than CVE-2015-5168...

UBUNTU-CVE-2017-5446

An out-of-bounds read when an HTTP/2 connection to a servers sends "DATA" frames with incorrect data content. This leads to a potentially exploitable crash. This vulnerability affects Thunderbird 52.1, Firefox ESR 45.9, Firefox ESR 52.1, and Firefox 53...
