Summary
RTSP RTP buffer over-read
Details

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 did not cause a crash). We have 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.
