We have just released GitLab 7.9.4 which fixes an unrestricted local repository import vulnerability. Additionally, this version addresses LDAP group synchronization problems in GitLab Enterprise Edition and a bug that would prevent more than 25 commit messages from being loaded in the file browser.
Unrestricted local repository import vulnerability
GitLab allows users to import an existing repository when creating a new project using
git clone. Insufficient sanitization of user input made it possible for an attacker with the rights to create new projects to clone any git repository on disk accessible to the
git user on the GitLab server. If the attacker could guess the path on disk to a Git repository they could clone it, allowing them to read Git data that they perhaps should not have access to. An attacker needs to be authenticated as a GitLab user and to have the right to create new projects to exploit this vulnerability.
Versions affected: GitLab Community Edition 7.9.3 and older, GitLab Enterprise Edition 7.9.3 and older.
See below for update instructions.
LDAP group synchronization problems (Enterprise Edition only)
We have recently discovered an incompatibility between the support for multiple LDAP servers (added in GitLab EE 7.4) and the support for multiple identities per user (e.g. LDAP, OAuth, Kerberos, added in GitLab 7.6). This incompatibility causes the gradual introduction of invalid data into the SQL database, which in turn causes LDAP group synchronization to stop working. In GitLab 7.9.4 we have made application code changes to avoid this prolem in the future. When you upgrade to GitLab 7.9.4 or newer any existing invalid data related to this issue is automatically purged and corrected.
GitLab 7.9.4 also fixes an issue where not all commit messages would get displayed in the file browser.
We recommend shutting down your GitLab instance before upgrading to 7.9.4 because this release includes database migrations. The migrations themselves run very quickly.
Omnibus packages for GitLab 7.9.4 can be found via our downloads page.
