CVE-2013-2236

Stack-based buffer overflow in the new_msg_lsa_change_notify function in the OSPFD API (ospf_api.c) in Quagga before 0.99.22.2, when --enable-opaque-lsa and the -a command line option are used, allows remote attackers to cause a denial of service (crash) via a large LSA.

Updated quagga packages fix security vulnerability:

Remotely exploitable buffer overflow in ospf_api.c and ospfclient.c when processing LSA messages in quagga before 0.99.22.2 (CVE-2013-2236).

Note: We have worked around this vulnerability by disabling the ospf_api and ospfclient features, which did not provide useful functionality.

These are all security issues fixed in the libospf0-1.0.20160315-5.1 package on the GA media of openSUSE Tumbleweed.
