CVE-2011-3347
Description
From CVE.org
A certain Red Hat patch to the be2net implementation in the kernel package before 2.6.32-218.el6 on Red Hat Enterprise Linux (RHEL) 6, when promiscuous mode is enabled, allows remote attackers to cause a denial of service (system crash) via non-member VLAN packets.
Statement
This has been addressed in Red Hat Enterprise Linux 5 via https://rhn.redhat.com/errata/RHSA-2011-1386.html. This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 4 as it did not include support for ServerEngines' 10Gbps network adapter - BladeEngine. This has been addressed in Red Hat Enterprise Linux 6 via https://rhn.redhat.com/errata/RHSA-2011-1530.html. A future kernel update in Red Hat Enterprise MRG may address this issue.
