* os: Eliminate uninitialized value warnings from access.cKeith Packard2016-10-061-8/+8
| | | | | | | | | | | | The ConvertAddr function doesn't reliably set the 'addr' return value, and so callers are getting flagged for using potentially uninitialized values. Initialize the value in the callers to NULL and then go ahead and check for NULL values before using them.

* dix: GetHosts bounds check using wrong pointer value [CVE-2014-8092 pt. 6]Keith Packard2016-10-061-1/+1
| | | | | | | | | | | | | | | GetHosts saves the pointer to allocated memory in *data, and then wants to bounds-check writes to that region, but was mistakenly using a bare 'data' instead of '*data'. Also, data is declared as void **, so we need a cast to turn it into a byte pointer so we can actually do pointer comparisons.

* Clear header file namespace separation (<X11/...> vs. <nx-X11/...>).Mike Gabriel2015-12-281-7/+7
| | | | | | | | | | | | | | | | | | | | In the process of building nxagent against more and more system-wide installed X.org libraries, we come to the limit of including structs from this (bundled nx-X11) and that (system-wide X.Org) library. This commit introduces a clear namespace separation of headers provided by nx-X11 and headers provided by X.Org. This approach is only temporary as we want to drop all nx-X11 bundled libraries from nx-libs. However, for a while we need to make this separation clear and also ship some reduced fake X.Org headers that avoid pulling in libX* and libNX_X* symbols at the same time. This patch has been tested on Debian jessie and unstable and requires no overall testing on various distros and distro versions, as we finally will drop all libNX_X* libraries and build against X.org's client libs. For now, this hack eases our development / cleanup process.
* Replace 'pointer' type with 'void *'Keith Packard2015-12-281-46/+46
| | | | | | | | | | This lets us stop using the 'pointer' typedef in Xdefs.h as 'pointer' is used throughout the X server for other things, and having duplicate names generates compiler warnings.

* dix: integer overflow in GetHosts() [CVE-2014-8092 2/4]Alan Coopersmith2015-02-161-0/+6
| | | | | | | | | | | | | | | | | | | | | GetHosts() iterates over all the hosts it has in memory, and copies them to a buffer. The buffer length is calculated by iterating over all the hosts and adding up all of their combined length. There is a potential integer overflow, if there are lots and lots of hosts (with a combined length of > ~4 gig). This should be possible by repeatedly calling ProcChangeHosts() on 64bit machines with enough memory. This patch caps the list at 1mb, because multi-megabyte hostname lists for X access control are insane. v2: backport to nx-libs 3.6.x (Mike DePaulo) v3: human-readable version of "1 MB" (Mihai Moldovan) Reported-by: Ilja Van Sprundel <ivansprundel@ioactive.com> Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com> Reviewed-by: Peter Hutterer <peter.hutterer@who-t.net> Conflicts: os/access.c
