Debian: DSA-4534-1 Critical: Golang HTTP Header Smuggling Issue

It was discovered that the Go programming language did accept and
normalize invalid HTTP/1.1 headers with a space before the colon, which
could lead to filter bypasses or request smuggling in some setups.

For the stable distribution (buster), this problem has been fixed in
version 1.11.6-1+deb10u2.

We recommend that you upgrade your golang-1.11 packages.

For the detailed security status of golang-1.11 please refer to
