CVE-2013-2236

Publication date 23 October 2013

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

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.

Notes

jdstrand

requires --enable-opaque-lsa during the build (true for Ubuntu 10.04 LTS and higher) also requires starting ospfd with '-a'. ospfd is not enabled by default and the configuration in /etc/quagga/debian.conf does not include '-a'. Per upstream, normal protection measures (eg, packet filtering, listening on internal network, etc) would prevent this. Furthermore, it is difficult to exploit. Considering the above, downgrading to 'low'
