Amazon Linux 2 : golang (ALAS-2021-1609)

high Nessus Plugin ID 146635

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 1.15.8-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2021-1609 advisory.

- In Go before 1.14.14 and 1.15.x before 1.15.7, crypto/elliptic/p224.go can generate incorrect outputs, related to an underflow of the lowest limb during the final complete reduction in the P-224 field.
(CVE-2021-3114)

- Go before 1.14.14 and 1.15.x before 1.15.7 on Windows is vulnerable to Command Injection and remote code execution when using the go get command to fetch modules that make use of cgo (for example, cgo can execute a gcc program from an untrusted download). (CVE-2021-3115)

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

Solution

Run 'yum update golang' to update your system.
