SCA: security update for github.com/opencontainers/runc (GHSA-xr7r-f8xq-vfvv)

high Tenable Cloud Security Plugin ID 420639

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 on Linux according to the OCI specification. In
 runc 1.1.11 and earlier, due to an internal file descriptor leak, an attacker could cause a newly-spawned
 container process (from runc exec) to have a working directory in the host filesystem namespace, allowing
 for a container escape by giving access to the host filesystem ("attack 2"). The same attack could be used
 by a malicious image to allow a container process to gain access to the host filesystem through runc run
 ("attack 1"). Variants of attacks 1 and 2 could be also be used to overwrite semi-arbitrary host binaries,
 allowing for complete container escapes ("attack 3a" and "attack 3b"). runc 1.1.12 includes patches for
 this issue. (CVE-2024-21626)
