Alpine: nghttp2: security update to 1.39.2-r1

high Tenable Cloud Security Plugin ID 405737

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In nghttp2 before version 1.41.0, the overly large HTTP/2 SETTINGS frame payload causes denial of service.
 The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of
 14,400 bytes (2400 individual settings entries) over and over again. The attack causes the CPU to spike at
 100%. nghttp2 v1.41.0 fixes this vulnerability. There is a workaround to this vulnerability. Implement
 nghttp2_on_frame_recv_callback callback, and if received frame is SETTINGS frame and the number of
 settings entries are large (e.g., > 32), then drop the connection. (CVE-2020-11080)
