Description Eugene Teo (Security Response) 2010-01-14 05:19:47 UTC

Description of problem:
commit dce766af541f6605fa9889892c0280bab31c66ab
Author: Florian Westphal <fwestphal>
Date:   Fri Jan 8 17:31:24 2010 +0100

    netfilter: ebtables: enforce CAP_NET_ADMIN
    
    normal users are currently allowed to set/modify ebtables rules.
    Restrict it to processes with CAP_NET_ADMIN.
    
    Note that this cannot be reproduced with unmodified ebtables
    binary
    because it uses SOCK_RAW.

Comment 2 Eugene Teo (Security Response) 2010-01-14 05:27:21 UTC

Note: impact=low/AC:H because ebtables binary uses SOCK_RAW which you need root privileges in the first place. rhel-3 doesn't have support for ebtables and the impact is low, so I didn't file a bug for it.
