Amazon Linux 2 : git (ALAS-2020-1409)

high Nessus Plugin ID 135594

Language:

Synopsis

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

Description

The version of git installed on the remote host is prior to 2.23.1-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2020-1409 advisory.

 With a crafted URL that contains a newline in it, the credential helper machinery can be fooled to give credential information for a wrong host. The attack has been made impossible by forbidding a newline character in any value passed via the credential protocol. (CVE-2020-5260)

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

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 git' to update your system.
