  security_fixes:
    - '**MEDIUM:** A security issue in nginx resolver was identified, where an attacker who could forge UDP packets from the DNS server could cause 1-byte memory overwrite, resulting in worker process crashes or other potentially damaging impacts. The vulnerability has been assigned [CVE-2021-23017](https://nvd.nist.gov/vuln/detail/CVE-2021-23017).'
    - Updated the `actions/checkout@v2` and `actions/checkout@v3` actions to address new vulnerabilities announced in the [Git security enforcement blog post](https://github.blog/2022-04-12-git-security-vulnerability-announced/).
    - Packages have been updated to the latest security versions.
  bugs:
    - In some cluster topologies, the `ghe-cluster-status` command left behind empty directories in `/tmp`.
    - SNMP incorrectly logged a high number of `Cannot statfs` error messages to syslog.
    - When adding custom patterns and providing non-UTF8 test strings, match highlighting was incorrect.
    - LDAP users with an underscore character (`_`) in their user names can now login successfully.
    - For instances configured with SAML authentication and built-in fallback enabled, built-in users would get stuck in a “login” loop when attempting to sign in from the page generated after logging out.
    - After enabling SAML encrypted assertions with Azure as identity provider, the sign in page would fail with a `500` error.
    - Character key shortcut preferences weren't respected.
    - Attempts to view the `git fsck` output from the `/stafftools/repositories/:owner/:repo/disk` page would fail with a `500 Internal Server Error`.
    - When using SAML encrypted assertions, some assertions were not correctly marking SSH keys as verified.
    - Videos uploaded to issue comments would not be rendered properly.
    - When using GitHub Enterprise Importer to import a repository, some issues would fail to import due to incorrectly configured project timeline events.
    - When using `ghe-migrator`, a migration would fail to import video file attachments in issues and pull requests.
    - 'The Releases page would return a 500 error when the repository has tags that contain non-ASCII characters. [Updated: 2022-06-10]'
    - 'Upgrades would sometimes fail while migrating dependency graph data. [Updated: 2022-06-30]'
  changes:
    - In high availability configurations, clarify that the replication overview page in the Management Console only displays the current replication configuration, not the current replication status.
    - The Nomad allocation timeout for Dependency Graph has been increased to ensure post-upgrade migrations can complete.
    - When enabling {% data variables.product.prodname_registry %}, clarify that using a Shared Access Signature (SAS) token as connection string is not currently supported.
    - Support bundles now include the row count of tables stored in MySQL.
    - When determining which repository networks to schedule maintenance on, we no longer count the size of unreachable objects.
    - The `run_started_at` response field is now included in the [Workflow runs API](/rest/actions/workflow-runs) and the `workflow_run` event webhook payload.
  known_issues:
    - On a freshly set up {% data variables.product.prodname_ghe_server %} instance without any users, an attacker could create the first admin user.
    - Custom firewall rules are removed during the upgrade process.
    - Git LFS tracked files [uploaded through the web interface](https://github.com/blog/2105-upload-files-to-your-repositories) are incorrectly added directly to the repository.
    - Issues cannot be closed if they contain a permalink to a blob in the same repository, where the blob's file path is longer than 255 characters.
    - When "Users can search GitHub.com" is enabled with {% data variables.product.prodname_github_connect %}, issues in private and internal repositories are not included in {% data variables.product.prodname_dotcom_the_website %} search results.
    - The {% data variables.product.prodname_registry %} npm registry no longer returns a time value in metadata responses. This was done to allow for substantial performance improvements. We continue to have all the data necessary to return a time value as part of the metadata response and will resume returning this value in the future once we have solved the existing performance issues.
    - Resource limits that are specific to processing pre-receive hooks may cause some pre-receive hooks to fail.

      After registering a self-hosted runner with the `--ephemeral` parameter on more than one level (for example, both enterprise and organization), the runner may get stuck in an idle state and require re-registration. [Updated: 2022-06-17]
    - After upgrading to {% data variables.product.prodname_ghe_server %} 3.4 releases may appear to be missing from repositories. This can occur when the required Elasticsearch index migrations have not successfully completed.

      GitHub Pages builds may time out on instances in AWS that are configured for high availability. [Updated: 2022-11-28]
