__________________________________________________ ____________________________

Announcement ID: openSUSE-SU-2012:1526-1
Rating: moderate
References: #761200
Cross-References: CVE-2012-2669
Affected Products:
openSUSE 12.2
openSUSE 12.1
__________________________________________________ ____________________________

An update that fixes one vulnerability is now available.

Description:

This update fixes the following issues for Hyper-V: The
source code without this patch caused hv_kvp_daemon to exit
when it processed a spoofed Netlink packet which has been
sent from an untrusted local user. Now Netlink messages
with a non-zero nl_pid source address are ignored and a
warning is printed into the syslog.

This fixes the previous change from CVE-2012-2669.
