An issue has been discovered in GitLab CE/EE affecting all versions starting from 16.1 before 16.1.3, all versions starting from 16.2 before 16.2.2. An invalid 'start_sha' value on merge requests page may lead to Denial of Service as Changes tab would not load.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An issue has been discovered in GitLab CE/EE affecting all versions starting from 16.1 before 16.1.3, all     versions starting from 16.2 before 16.2.2. An invalid 'start_sha' value on merge requests page may lead to     Denial of Service as Changes tab would not load. (CVE-2023-3900)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the fa239535-30f6-11ee-aef9-001b217b3468 advisory.
