v4.2.3-P1 imported from ftp://ftp.isc.org/isc/dhcp/4.2.3-P1/dhcp-4.2.3-P1.tar.gzv4.2.3-P1
Changes since 4.2.3
! Add a check for a null pointer before calling the regexec function.
Without out this check we could, under some circumstances, pass
a null pointer to the regexec function causing it to segfault.
Thanks to a report from BlueCat Networks.
[ISC-Bugs #26704].
