CVE-2014-3640

Publication date 7 November 2014

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

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.
