CVE-2012-6689 libmnl: incorrect validation of netlink message origin allows attackers to spoof netlink messages
Last modified: 2015-03-02 06:14:22 EST
Florian Weimer of the Red Hat Product Security Team discovere that the mnl_nlmsg_portid_ok() function in libmnl 1.0.3 and earlier did not correctly validate the origin of a Netlink message, allowing local attackers to spoof Netlink messages, with context-dependent consequences.
This is currently being discussed here:
but in the capacity of the kernel, not libmnl.
This was fixed in the kernel, see bug 851968.
