Description Robert Frohl 2023-03-29 11:09:52 UTC
CVE-2023-28642

Impact:
  It was found that AppArmor, and potentially SELinux, can be bypassed when /proc inside the container is symlinked with a specific mount configuration.

Patches: 
  Fixed in runc v1.1.5, by prohibiting symlinked /proc: #3785

  This PR fixes bsc#1208962 as well.

Workarounds:
  Avoid using an untrusted container image.
