CVE-2013-0343: Low severity linux kernel vulnerability

Published Feb 22, 2013
·
Updated

Due to the way the Linux kernel handles the creation of IPv6 temporary addresses a malicious LAN user can remotely disable them altogether which may lead to privacy violations and information disclosure.

Reference: -> http://seclists.org/oss-sec/2012/q4/292 -> http://seclists.org/oss-sec/2013/q1/92

Other sources

The ipv6createtempaddr 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.
