Discovered: 10.30.08. Reported: 10.30.08. Disclosed: 10.31.08. QNX’s ker_msg_sendv() system call contains an integer overflow that could lead to heap corruption and, if correctly exploited, system compromise. If only partially exploited, this could lead to denial-of-service conditions and kernel panic, effectively shutting down the system.
