Fixed In Version: | dhcp-4.1.1-22.P1.el6 | Doc Type: | Bug Fix | ||||
Doc Text: |
If the system included network interfaces with no hardware address, the dhcpd scan could have caused a segmentation fault when scanning such an interface. As a consequence, the dhcp daemon unexpectedly terminated. To prevent this issue, dhcpd now tests a pointer which represents the hardware address of the interface for the NULL value. The dhcp daemon no longer crashes.
