bgpd/security: CVE-2010-1674 Fix crash due to extended-community parser error
* bgp_attr.c: (bgp_attr_ext_communities) Certain extended-community attrs
can leave attr->flag indicating ext-community is present, even though no
extended-community object has been attached to the attr structure. Thus a
null-pointer dereference can occur later.
(bgp_attr_community) No bug fixed here, but tidy up flow so it has same
form as previous.
Problem and fix thanks to anonymous reporter.
(cherry picked from commit 0c46638122f10019a12ae9668aec91691cf2e017)
