Description Pedro Sampaio 2018-03-08 19:29:14 UTC 
curl can be tricked into copying data beyond end of its heap based buffer.

When asked to transfer an RTSP URL, curl could calculate a wrong data length
to copy from the read buffer. The memcpy call would copy data from the heap
following the buffer to a storage area that would subsequently be delivered to
the application (if it didn't cause a crash). We've managed to get it to reach
several hundreds bytes out of range.

This could lead to information leakage or a denial of service for the
application if the server offering the RTSP data can trigger this.
