Summary
VRPN through 07.36 Out-of-bounds Write via SENDER_DESCRIPTION/TYPE_DESCRIPTION length index
Details

VRPN through 07.36 contains an out-of-bounds stack write vulnerability in vrpn_Endpoint::handle_sender_message() and handle_type_message() that allows unauthenticated remote peers to write outside a stack buffer via an unchecked length index. Attackers can connect, complete the version-cookie exchange, and send a SENDER_DESCRIPTION or TYPE_DESCRIPTION message with an out-of-range or negative index to crash the process.
