An issue has been discovered in GitLab CE/EE affecting all versions
starting from 14.3 before 15.6.7, all versions starting from 15.7 before
15.7.6, all versions starting from 15.8 before 15.8.1. An attacker may
upload a crafted CI job artifact zip file in a project that uses dynamic
child pipelines and make a sidekiq job allocate a lot of memory. In GitLab
instances where Sidekiq is memory-limited, this may cause Denial of
Service.
