Amazon Linux 2022 : golang, golang-bin, golang-misc (ALAS2022-2021-007)

critical Nessus Plugin ID 212485

Synopsis

The remote Amazon Linux 2022 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2021-007 advisory.

A validation flaw was found in golang. When invoking functions from WASM modules built using GOARCH=wasm GOOS=js, passing very large arguments can cause portions of the module to be overwritten with data from the arguments. The highest threat from this vulnerability is to integrity. (CVE-2021-38297)

An out of bounds read vulnerability was found in debug/macho of the Go standard library. When using the debug/macho standard library (stdlib) and malformed binaries are parsed using Open or OpenFat, it can cause golang to attempt to read outside of a slice (array) causing a panic when calling ImportedSymbols.
An attacker can use this vulnerability to craft a file which causes an application using this library to crash resulting in a denial of service. (CVE-2021-41771)

A vulnerability was found in archive/zip of the Go standard library. Applications written in Go where Reader.Open (the API implementing io/fs.FS introduced in Go 1.16) can panic when parsing a crafted ZIP archive containing completely invalid names or an empty filename argument. (CVE-2021-41772)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'dnf update --releasever=2022.0.20211217 golang' to update your system.
