Descriptions

An issue has been discovered in GitLab CE/EE affecting all versions starting from 10.8 before 15.5.7, all versions starting from 15.6 before 15.6.4, all versions starting from 15.7 before 15.7.2. An attacker may cause Denial of Service on a GitLab instance by exploiting a regex issue in how the application parses user agents.
