* XIM: Make Xim handle NEED_SYNC_REPLY flagChoe Hwanjin2016-10-195-47/+27
| | | | | | | | | | | | | | | | NEED_SYNC_REPLY flag should be in Xim not in Xic. Because the focused Xic can be changed before sending sync reply. After focused Xic changed, the new Xic doesn't have NEED_SYNC_REPLY flag enabled, so libX11 doesn't send XIM_SYNC_REPLY packet. This patch adds sync reply flag to Xim and removes sync reply from Xic.

* cmsProp: don't deal with uninitialized values, fail insteadErkki Seppälä2016-10-191-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Properly handle the return value of XGetWindowProperty by considering if after the loop as well. Using freed pointer "prop_ret" There were numerous things wrong in how this function interacted with XGetWindowProperty. None of the local variables were initialized and remained that way if the call to XGetWindowProperty returned 1 (not Succeed). That doesn't result in after_ret being initialized in which case if it happens to be 0, the loop was exited. In that case format_ret and nitems_ret were uninitialized and the function might return with success (but with uninitialized pointer in prop_ret) or XcmsFailure. As the buffer enlarging code was called only when XGetWindowProperty failed (returned not Success), after_ret would not have been initialized. It would have been initialized only if the XGetWindowProperty has returned Success earlier, but in that case the code fragment would not have been reached. This patch alters the function to return XcmsFailure if the call to XGetWindowProperty fails.

* Unbounded recursion in GetDatabase() when parsing include files ↵Alan Coopersmith2016-10-121-9/+15
| | | | | | | | | | | | | | | | | | | [CVE-2013-2004 1/2] GetIncludeFile() can call GetDatabase() which can call GetIncludeFile() which can call GetDatabase() which can call GetIncludeFile() .... eventually causing recursive stack overflow and crash. Easily reproduced with a resource file that #includes itself. Limit is set to a include depth of 100 files, which should be enough for all known use cases, but could be adjusted later if necessary.
