Amazon Linux 2 : golang, --advisory ALAS2-2022-1830 (ALAS-2022-1830)

high Nessus Plugin ID 163918

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of golang installed on the remote host is prior to 1.18.3-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1830 advisory.

A null pointer dereference vulnerability was found in golang. When using the library's ssh server without specifying an option for GSSAPIWithMICConfig, it is possible for an attacker to craft an ssh client connection using the authentication method and cause the server to panic resulting in a denial of service. The highest threat from this vulnerability is to system availability. (CVE-2020-29652)

A buffer overflow flaw was found in Golang's library encoding/pem. This flaw allows an attacker to use a large PEM input (more than 5 MB) ), causing a stack overflow in Decode, which leads to a loss of availability. (CVE-2022-24675)

An integer overflow flaw was found in Golang's crypto/elliptic library. This flaw allows an attacker to use a crafted scaler input longer than 32 bytes, causing P256().ScalarMult or P256().ScalarBaseMult to panic, leading to a loss of availability. (CVE-2022-28327)

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 'yum update golang' or or 'yum update --advisory ALAS2-2022-1830' to update your system.
