Golang: stdlib: security update to 1.26.9stdlib: security update to 1.27.2

high Tenable Self-Hosted Container Security Plugin ID 473920

Description

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

- HTTP/2 servers could end up crashing due to inadvertently modifying its HPACK encoder concurrently. This
happens because the server modifies the HPACK encoder from two goroutines without synchronization: one
uses the encoder to encode a HEADERS frame as part of a response sent to a client and the other modifies
the encoder's table size when handling a SETTINGS frame containing SETTINGS_HEADER_TABLE_SIZE that a
client sends. A malicious client can repeatedly send a request while changing the header table size to
crash the server. (CVE-2026-97032)

Solution

Update the stdlib library and its related packages to version 1.26.9 or later.
