Description

This security bulletin contains information about 1 security vulnerability.


1) Input validation error (CVE-ID: CVE-2013-0343)

The vulnerability allows a remote non-authenticated attacker to #BASIC_IMPACT#.

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.


Remediation

Install update from vendor's website.
