Advisory Release Date: 2012-09-10 17:56 Pacific
Advisory Updated Date: 2014-09-14 16:56 Pacific
Severity:
Medium
Issue Overview:
The Netlink implementation in the Linux kernel before 3.2.30 does not properly handle messages that lack SCM_CREDENTIALS data, which might allow local users to spoof Netlink communication via a crafted message, as demonstrated by a message to (1) Avahi or (2) NetworkManager.
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.
