EulerOS 2.0 SP8 : nghttp2 (EulerOS-SA-2019-2083)
High Nessus Plugin ID 129442
SynopsisThe remote EulerOS host is missing a security update.
DescriptionAccording to the version of the nghttp2 package installed, the EulerOS installation on the remote host is affected by the following vulnerability :
- Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate 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 can consume excess CPU, memory, or both.(CVE-2019-9511)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected nghttp2 package.
