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 PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU.

Node.js is a software development platform for building fast and scalable network applications in the JavaScript programming language.

The following packages have been upgraded to a later upstream version: nodejs (10.16.3).

Security Fix(es):

• HTTP/2: large amount of data requests leads to denial of service (CVE-2019-9511)

• HTTP/2: flood using PING frames results in unbounded memory growth (CVE-2019-9512)

• HTTP/2: flood using PRIORITY frames results in excessive resource consumption (CVE-2019-9513)

• HTTP/2: flood using HEADERS frames results in unbounded memory growth (CVE-2019-9514)

• HTTP/2: flood using SETTINGS frames results in unbounded memory growth (CVE-2019-9515)

• HTTP/2: 0-length headers lead to denial of service (CVE-2019-9516)

• HTTP/2: request for large response leads to denial of service (CVE-2019-9517)

• HTTP/2: flood using empty frames results in excessive resource consumption (CVE-2019-9518)
