Alpine: nginx: security update to 1.14.1-r2
high Tenable Self-Hosted Container Security Plugin ID 405755
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- 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)
- Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service.
The attacker creates multiple request streams and continually shuffles the priority of the streams in a
way that causes substantial churn to the priority tree. This can consume excess CPU. (CVE-2019-9513)
- 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 for these headers and
keep the allocation alive until the session dies. This can consume excess memory. (CVE-2019-9516)
