Alpine: multiple runc packages: security update to 1.1.2-r0
high Tenable Self-Hosted Container Security Plugin ID 407021
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. A bug
was found in runc prior to version 1.1.2 where `runc exec --cap` created processes with non-empty
inheritable Linux process capabilities, creating an atypical Linux environment and enabling programs with
inheritable file capabilities to elevate those capabilities to the permitted set during execve(2). This
bug did not affect the container security sandbox as the inheritable set never contained more capabilities
than were included in the container's bounding set. This bug has been fixed in runc 1.1.2. This fix
changes `runc exec --cap` behavior such that the additional capabilities granted to the process being
executed (as specified via `--cap` arguments) do not include inheritable capabilities. In addition, `runc
spec` is changed to not set any inheritable capabilities in the created example OCI spec (`config.json`)
file. (CVE-2022-29162)
