Amazon Linux AMI : runc (ALAS-2021-1499)

high Nessus Plugin ID 149783

Synopsis

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

Description

The version of runc installed on the remote host is prior to 1.0.0-0.3.20210225.git12644e6.4. It is, therefore, affected by a vulnerability as referenced in the ALAS-2021-1499 advisory.

The runc package is vulnerable to a symlink exchange attack whereby an attacker can request a seemingly innocuous container configuration that results in the host filesystem being bind-mounted into the container. The highest threat from this vulnerability is to data confidentiality and integrity as well as to system availability. (CVE-2021-30465)

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 runc' to update your system.
