The MapServer team is pleased (kinda) to announce the 7.6.3 security and
maintenance release.
Importantly, this release addresses a flaw, discovered by project
developers, in MapServer CGI mapfile loading that makes it possible to
bypass security controls (ticket #6313). This flaw makes it difficult to
easily limit where MapServer can load a mapfile from and affects
versions 4.10 and later. This is a critical issue and all users are
encouraged to update as soon as possible.
What does this mean for you?
1. If you've not used MS_MAP_PATTERN or MS_MAP_NO_PATH as part of
securing your installation then this doesn't have much impact since
you're not using the controls. That said, this is a critical
configuration step and you should upgrade and make use of those
controls to limit where mapfiles can be accessed.
2. If you've relied on MS_MAP_PATTERN exclusively, you should upgrade
and be in good shape. However, it's a great time to review and test
MS_MAP_PATTERN.
3. If you've relied on MS_MAP_NO_PATH primarily (like me), you should
upgrade and set a value for MS_MAP_PATTERN.
We are simultaneously releasing versions 7.0.8, 7.2.3 and 7.4.5 as well.
Updates to binary distributions will follow ASAP.
