CVE-2014-3640: Null Pointer Dereference
First published: Sun Sep 21 2014(Updated: )
The sosendto function in slirp/udp.c in QEMU before 2.1.2 allows local users to cause a denial of service (NULL pointer dereference) by sending a udp packet with a value of 0 in the source port and address, which triggers access of an uninitialized socket.
