From 370b64a2ad38e43b4bed028960481bbf4192becd Mon Sep 17 00:00:00 2001 From: Paul Jakma Date: Sat, 22 Dec 2007 16:49:52 +0000 Subject: [bgpd] Fix number of DoS security issues, restricted to configured peers. 2007-12-22 Paul Jakma * Fix series of vulnerabilities reported by "Mu Security Research Team", where bgpd can be made to crash by sending malformed packets - requires that bgpd be configured with a session to the peer. * bgp_attr.c: (bgp_attr_as4_path) aspath_parse may fail, only set the attribute flag indicating AS4_PATH if we actually managed to parse one. (bgp_attr_munge_as4_attrs) Assert was too general, it is possible to receive AS4_AGGREGATOR before AGGREGATOR. (bgp_attr_parse) Check that we have actually received the extra byte of header for Extended-Length attributes. * bgp_attr.h: Fix BGP_ATTR_MIN_LEN to account for the length byte. * bgp_open.c: (cap_minsizes) Fix size of CAPABILITY_CODE_RESTART, incorrect -2 left in place from a development version of as4-path patch. * bgp_packet.c: (bgp_route_refresh_receive) ORF length parameter needs to be properly sanity checked. * tests/bgp_capability_test.c: Test for empty capabilities. --- tests/ChangeLog | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'tests/ChangeLog') diff --git a/tests/ChangeLog b/tests/ChangeLog index 94f58749..16412bde 100644 --- a/tests/ChangeLog +++ b/tests/ChangeLog @@ -1,3 +1,7 @@ +2007-12-22 Paul Jakma + + * bgp_capability_test.c: Test for empty capabilities. + 2007-09-27 Paul Jakma * aspath_test.c: Test dupe-weeding from sets. -- cgit v1.2.1
