Security Fixes

Bug Fixes

• Users in large organizations and teams were unable to filter assignees and reviewers for issues and pull requests.
• Users in large organizations and teams were unable to @-mention users and teams in issue and pull request comments.
• /setup/replication in the Management console returned a '500 Internal Server Error' when replication was not running.
• In a clustering environment, collectd statistics weren't reported for the workers that handle RPC calls for Git.
• In a clustering environment, preflight checks failed when running ghe-cluster-config-apply against an unresponsive HTTP proxy.
• In a clustering environment, a new node could silently fail to be added after ghe-cluster-config-init.

Changes

• memcached collectd stats have been added.

Known Issues

• We incorrectly redirect to the dashboard if you accessed GitHub Enterprise using an alias while in private mode. This might happen if you set a fully qualified domain name but the subdomain resolves correctly.
• Images uploaded to issues save with an absolute URL, so they can be broken if the hostname changes.
• On a freshly set up GitHub Enterprise without any users, an attacker could create the first admin user.
• Custom firewall rules aren't maintained during an upgrade.
• Enqueued background jobs are sometimes not purged when a repository is deleted.
• svn checkout may timeout while the repository data cache is being built. In most cases, subsequent svn checkout attempts will succeed.
• Git LFS tracked files uploaded through the web interface are incorrectly added directly to the repository.
• GitHub Enterprise clustering can not be configured without https.
• Deleting a search index doesn't delete all associated metadata, which are then incorrectly reused if a new search index is created. This causes search index repair jobs to be reported as finished in the site admin when they were not.
• /setup/replication in the Management console returns a '500 Internal Server Error' when replication is configured. (updated 2017-06-27)
• Webhook requests incorrectly ignore local search domains when resolving hosts, which can result in "Couldn't resolve host name" errors. (updated 2017-07-10)
• collectd metric paths can be truncated, which causes multiple write attempts to the same file for different metrics. (updated 2017-07-10)
• Background jobs are added to the "toggle_hidden_user_in_notifications" queue, but these jobs aren't processed on GitHub Enterprise. The entries are harmless but will show in ghe-resque-info output and in management console graphs. (updated 2017-07-13)
• Using ghe-migrator, protected branch settings are always migrating with push restrictions enabled. (updated 2017-08-01)
• After changing the visibility of a repository, wiki search results have a conflicting number of displayed search results. Administrators can reindex the wiki through the site admin dashboard. (updated 2017-11-09)
• The create team API endpoint returns a 500 error if LDAP Sync is enabled and the team already exists. (updated 2018-01-09)
• Pull request reviewer usernames were not updated if a reviewer was mapped to a different username when migrating repositories using ghe-migrator. (updated 2018-04-12)
