Amazon Linux 1 Security Advisory: ALAS-2013-228
Advisory Release Date: 2013-09-24 19:43 Pacific
Advisory Updated Date: 2014-09-16 21:40 Pacific
Severity:
Medium
Issue Overview:
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.
Affected Packages:
kernel
Issue Correction:
Run yum update kernel to update your system. You will need to reboot your system in order for the new kernel to be running.
