Bottlerocket: bottlerocket-runc, runc: security update to 1.2.7

high Tenable Cloud Security Plugin ID 435995

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - runc is a CLI tool for spawning and running containers according to the OCI specification. In versions
 1.2.7 and below, 1.3.0-rc.1 through 1.3.1, 1.4.0-rc.1 and 1.4.0-rc.2 files, runc would not perform
 sufficient verification that the source of the bind-mount (i.e., the container's /dev/null) was actually a
 real /dev/null inode when using the container's /dev/null to mask. This exposes two methods of attack: an
 arbitrary mount gadget, leading to host information disclosure, host denial of service, container escape,
 or a bypassing of maskedPaths. This issue is fixed in versions 1.2.8, 1.3.3 and 1.4.0-rc.3.
