Amazon Linux AMI update for golang

1) Code Injection

EUVDB-ID: #VU77528

Risk: Medium

CVSSv4.0: 4.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2023-29402

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to improper input validation within the cgo go command when building code that contains directories with newline characters in their names. A remote attacker can pass specially crafted input to the cgo command at build time and potentially compromise the system.

Modules which are retrieved using the go command, i.e. via "go get", are not affected (modules retrieved using GOPATH-mode, i.e. GO111MODULE=off, may be affected).

Mitigation

Update the affected packages:

i686:
    golang-bin-1.18.6-1.45.amzn1.i686
    golang-1.18.6-1.45.amzn1.i686
    golang-shared-1.18.6-1.45.amzn1.i686

noarch:
    golang-src-1.18.6-1.45.amzn1.noarch
    golang-tests-1.18.6-1.45.amzn1.noarch
    golang-docs-1.18.6-1.45.amzn1.noarch
    golang-misc-1.18.6-1.45.amzn1.noarch

src:
