* dix: integer overflow in ProcPutImage() [CVE-2014-8092 1/4]Alan Coopersmith2015-05-301-1/+3
| | | | | | | | | | | | | | | | | | | ProcPutImage() calculates a length field from a width, left pad and depth specified by the client (if the specified format is XYPixmap). The calculations for the total amount of memory the server needs for the pixmap can overflow a 32-bit number, causing out-of-bounds memory writes on 32-bit systems (since the length is stored in a long int variable). v2: backport to nx-libs 3.6.x (Mike DePaulo) v3: port to NXdispatch.c rather than dispatch.c (Mike DePaulo) 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: dix/dispatch.c
* Avoid use-after-free in dix/dixfonts.c: doImageText() [CVE-2013-4396] from ↵Mike DePaulo2015-05-301-0/+5
| | | | | | | | | | | | | | | | | | | | | | | xorg/Xserver http://lists.x.org/archives/xorg-announce/2013-October/002332.html Save a pointer to the passed in closure structure before copying it and overwriting the *c pointer to point to our copy instead of the original. If we hit an error, once we free(c), reset c to point to the original structure before jumping to the cleanup code that references *c. Since one of the errors being checked for is whether the server was able to malloc(c->nChars * itemSize), the client can potentially pass a number of characters chosen to cause the malloc to fail and the error path to be taken, resulting in the read from freed memory. Since the memory is accessed almost immediately afterwards, and the X server is mostly single threaded, the odds of the free memory having invalid contents are low with most malloc implementations when not using memory debugging features, but some allocators will definitely overwrite the memory there, leading to a likely crash. v2: Apply to NXdixfonts.c rather than dixfonts.c (Mike DePaulo)

| | | | | | | | | | | NX agent contains/ed two build trees. An old one (probably pre-3.x.y) and a "newer" one. The "newer" code tree used to become enabled by setting NXUpgradeAgentServer in nx-X11/config/cf/host.def to YES. As building the NXUpgradeAgentServer has been the default for years now, we drop all code that does not get used at build time for NXUpgradeAgentServer == YES (i.e., the code that belongs to the pre-3.x.y phase of NX agent).

| | | | | | | | | | | | | | | | | | | Cherry-picked from branch 3.5.0.x. This is basically a merge of the most current xorg-server (1.17.1) code into nx-X11. It makes sure that for source pictures, which do not have a drawable surface, a filter is selected that is supported on the "main" and all other screens. Alternatively, if the requested filter is not available on all screens and the picture is a source picture, this function fails gracefully. Additionally, the ChangePictureFilter hook is now called for non-source pictures. This also needs an implementation in mipict.{c,h}. The default hook does nothing and returns a success value.

* xkb: Don't swap XkbSetGeometry data in the input bufferOlivier Fourdan2015-02-171-16/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | The XkbSetGeometry request embeds data which needs to be swapped when the server and the client have different endianess. _XkbSetGeometry() invokes functions that swap these data directly in the input buffer. However, ProcXkbSetGeometry() may call _XkbSetGeometry() more than once (if there is more than one keyboard), thus causing on swapped clients the same data to be swapped twice in memory, further causing a server crash because the strings lengths on the second time are way off bounds. To allow _XkbSetGeometry() to run reliably more than once with swapped clients, do not swap the data in the buffer, use variables instead. v3: backport to nx-libs 3.6.x as a prereq for the CVE-2015-0255 fix (Mike DePaulo) Signed-off-by: Olivier Fourdan <ofourdan@redhat.com> Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> (cherry picked from commit 81c90dc8f0aae3b65730409b1b615b5fa7280ebd) (cherry picked from commit 29be310c303914090298ddda93a5bd5d00a94945) Signed-off-by: Julien Cristau <jcristau@debian.org> index 2405090..7db0959 100644
* include: introduce byte counting functions.Peter Hutterer2015-02-171-0/+30
| | | | | | | | | | | | | | | | | | | | This patch adds the following three functions: bits_to_bytes(bits) - the number of bytes needed to hold 'bits' bytes_to_int32(bytes) - the number of 4-byte units to hold 'bytes' pad_to_int32(bytes) - the closest multiple of 4 equal to or larger than 'bytes'. All three operations are common in protocol processing and currently the server has ((foo + 7)/8 + 3)/4 operations all over the place. A common set of functions reduce the error rate of these (albeit simple) calculations and improve readability of the code. The functions do not check for overflow. v2: backport to nx-libs 3.6.x as a prereq for the CVE-2015-0255 fix (Mike DePaulo) Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>

* Make nxagent process aware of its current NX'ish version.Mike Gabriel2015-02-172-3/+9
| | | | | | | | | | | This feature copies the way how X.Org version string and number are propagated at build time. First use case: if people start nxagent, it reports its version number on stderr. This is about being human-friendly. Second use case: None, so far. But it will now be easy to use the NXAGENT_VERSION_STRING in later feature add-ons.

* 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
