>> This fixes a number of issues with dodgy path handling

>> Many improvements in this release are related to security

We do not see a straightforward way to determine the total number of
independent vulnerabilities. For example:

  Paths like .., ../.. or // are not sanitized correctly

  The program crashes if a path doesn't start with base_prefix instead of showing an error message

  On MS Windows the filesystem backend allows access to the first level of files on a drive.

  Improve the regex used for well-known URIs

  Decouple the daemon from its parent environment

  Avoid race condition in PID file creation

are missing information about the attacker and/or the impact.



These might potentially be overlapping observations:

  Paths like .., ../.. or // are not sanitized correctly

  Improve the regex used for well-known URIs

  Prevent crafted HTTP request from calling arbitrary functions

  Improve URI sanitation and conversion to filesystem path

  

For now, we will start with two CVE IDs for the change information that
seems somewhat more clear:

CVE-2015-8747 - The multifilesystem backend allows access to arbitrary files on all platforms.

CVE-2015-8748 - Prevent regex injection in rights management
