CVE-2020-29509  (opens in a new tab)

How to fix?

Upgrade Alpine:3.21 go to version 1.17-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream go package and not the go package as distributed by Alpine. See How to fix? for Alpine:3.21 relevant fixed versions and status.

The encoding/xml package in Go (all versions) does not correctly preserve the semantics of attribute namespace prefixes during tokenization round-trips, which allows an attacker to craft inputs that behave in conflicting ways during different stages of processing in affected downstream applications.
