CVE-2013-4470

Published: 4 November 2013

The Linux kernel before 3.12, when UDP Fragmentation Offload (UFO) is enabled, does not properly initialize certain data structures, which allows local users to cause a denial of service (memory corruption and system crash) or possibly gain privileges via a crafted application that uses the UDP_CORK option in a setsockopt system call and sends both short and long packets, related to the ip_ufo_append_data function in net/ipv4/ip_output.c and the ip6_ufo_append_data function in net/ipv6/ip6_output.c.

From the Ubuntu Security Team

Hannes Frederic Sowa discovered a flaw in the Linux kernel's UDP Fragmentation Offload (UFO). An unprivileged local user could exploit this flaw to cause a denial of service (system crash) or possibly gain administrative privileges.
