In Ubuntu, the attached patch was applied to achieve the following:
* SECURITY UPDATE: denial of service via circular reference
- debian/patches/CVE-2010-3609.patch: detect circular reference in
common/slp_message.c. Patch thanks to SUSE.
- CVE-2010-3609
* debian/rules: add dh_quilt_patch and dh_quilt_unpatch so patches in
debian/patches actually get applied.
* debian/patches/series: disable 01_have_net_if_arp.diff and
99_autoreconf.diff since they had never been applied.
Thanks for considering the patch.
