Package: isc-dhcp-server
Version: 4.3.1-6+deb8u2
Severity: important
Tags: ipv6
Dear Maintainer,
After a random time depending on the amount of DDNS updates requested, a
SEGV signo is
issued, causing the daemon to exit.
The core analysis reports:
Core was generated by `/usr/sbin/dhcpd -f -d -6 -cf
/etc/dhcp/dhcpd6.conf -pf /var/run/dhcpd6.pid eth3'.
Program terminated with signal SIGSEGV, Segmentation fault.
