* crypto: move to commonChristian Beier2018-06-295-190/+0
| | | | | | As of now, only LibVNCServer makes uses of these digest functions _and_ they depend on sys/uio.h, but in the future LibVNCClient will need those as well.
* Tight: export SendCompressedData and SendTightHeader functionsEddie James2018-06-201-14/+11
| | | | | | | | | These functions can be used to send already compressed jpegs to a client, circumventing the usual rect/region update methods which operate on a raw rgb framebuffer. Rename the functions with the usual rfb prefix and add the prototypes in rfb.h. Signed-off-by: Eddie James <eajames@us.ibm.com>

* Limit client cut text length to 1 MBPetr Písař2018-03-081-1/+19
| | | | | | | | | | | | | | | | This patch constrains a client cut text length to 1 MB. Otherwise a client could make server allocate 2 GB of memory and that seems to be to much to classify it as a denial of service. The limit also prevents from an integer overflow followed by copying an uninitilized memory when processing msg.cct.length value larger than SIZE_MAX or INT_MAX - sz_rfbClientCutTextMsg. This patch also corrects accepting length value of zero (malloc(0) is interpreted on differnet systems differently). CVE-2018-7225 <https://github.com/LibVNC/libvncserver/issues/218>

| | | | | | | | | | | | | | | | | | Make it possible to get autoPort behavior with either ipv4 or ipv6 disabled, by setting rfbScreen->ipv6port or rfbScreen->port to a negative number. This will make it possible for x11vnc to enforce its -noipv6 option, as discussed in the following bug report: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=672449

* | Avoid calling SSL_pending when connection is already closedGeorge Fleury2016-05-131-1/+1
| | | | | | | | Avoid calling SSL_pending when connection is already closed, calling SSL_pending with connection already closed is crashing. To reproduce, open a secure websocket binay protocol connection with libvncserver compiled with OpenSSL, and when libvncserver is waiting for rfbProcessClientProtocolVersion send any invalid char, it will fail and call rfbCloseClient whith destroy all SSL context, calling SSL_pending after that will generate a invalid access.
