How to fix?

Upgrade RHEL:6 python-perf to version 0:2.6.32-431.el6 or higher.
This issue was patched in RHSA-2013:1645.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python-perf package and not the python-perf package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

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.
