CVE-2013-0343 Information

Description

The ipv6_create_tempaddr function in net/ipv6/addrconf.c in the Linux kernel through 3.8 does not properly handle problems with the generation of IPv6 temporary addresses which allows remote attackers to cause a denial of service (excessive retries and address-generation outage) and consequently obtain sensitive information via ICMPv6 Router Advertisement (RA) messages.
