Bugfix Releases

2.9.5

  • Issue 10262: Fix validation of wants in git-upload-pack for protocol v0 stateless transports.

    See the following section for details.

  • Upgrade JGit to 4.5.5.201812240535-r.

    This upgrade includes several major versions since 3.4.2 used in Gerrit version 2.9.4. Important fixes are summarized below. Please refer to the corresponding JGit release notes for full details.

    • JGit 4.5.5:

      • Issue 10262: Fix validation of wants in git-upload-pack for protocol v0 stateless transports.

        AdvertiseRefsHook was not called for git-upload-pack in protocol v0 stateless transports, meaning that wants were not validated and a user could fetch anything that is pointed to by any ref (using fetch-by-sha1), as long as they could guess the object name.

    • JGit 4.5.4:

      • Fix LockFile semantics when running on NFS.
      • Honor trustFolderStats also when reading packed-refs.

    • JGit 4.5.3:

      • Fix exception handling for opening bitmap index files.

    • JGit 4.5.2:

      • Fix pack marked as corrupted even if it isn't.

    • JGit 4.5.1:

      • Don't remove Pack when FileNotFoundException is transient.

    • JGit 4.1.0:

      • Handle stale NFS file handles on packed-refs file.
      • Use java.io.File instead of NIO to check existence of loose objects in ObjectDirectory to speed up inserting of loose objects.
      • Reduce memory consumption when creating bitmaps during writing pack files.

    • JGit 3.7.1:

      • Fix massive performance problem in Gerrit caused by ObjectWalk.markUninteresting marking the root tree as uninteresting.

    • JGit 3.7.0:

      • Provide more details in exceptions thrown when packfile is invalid.

    • JGit 3.6.2:

      • Issue 3094: Don't remove pack from pack list for problems which could be transient.

      • Log reason for ignoring pack when IOException occurred.

    • JGit 3.5.3:

      • Fix for vulnerability CVE-2014-9390.

  • Fix resource exhaustion due to unclosed LDAP connection.

    When auth.type is set to LDAP (not LDAP_BIND), two LDAP connections are made, but one was not being closed. This eventually caused resource exhaustion and LDAP authentications failed.
