test script: doc/examples/run-nxproxy2nxproxy-test

2015-04-15T10:37:30+00:00

Launch this script (after nxproxy has been installed into $PATH) and you will be able to evoke any local command through a nxproxy -C <-> nxproxy -S connection on DISPLAY=:8. This eases testing NX compression without using NX agent on the server side. How to use: # install nxproxy into $PATH, then... $ cd doc/examples/ $ ./run-nxproxy2nxproxy-test $ export DISPLAY=:8 $ xterm

MakeBigReq: don't move the last word, already handled by Data32 (X.Org CVE-2013-7439).

2015-04-15T08:16:18+00:00

MakeBigReq inserts a length field after the first 4 bytes of the request (after req->length), pushing everything else back by 4 bytes. The current memmove moves everything but the first 4 bytes back. If a request aligns to the end of the buffer pointer when MakeBigReq is invoked for that request, this runs over the buffer. Instead, we need to memmove minus the first 4 bytes (which aren't moved), minus the last 4 bytes (so we still align to the previous tail). The 4 bytes that fell out are already handled with Data32, which will handle the buffermax correctly. The case where req->length = 1 was already not functional.
