Mandriva Linux Security Advisory 2012-115 - An unexpected client identifier parameter can cause the ISC DHCP daemon to segmentation fault when running in DHCPv6 mode, resulting in a denial of service to further client requests. In order to exploit this condition, an attacker must be able to send requests to the DHCP server. An error in the handling of malformed client identifiers can cause a DHCP server running affected versions to enter a state where further client requests are not processed and the server process loops endlessly, consuming all available CPU cycles. Under normal circumstances this condition should not be triggered, but a non-conforming or malicious client could deliberately trigger it in a vulnerable server. In order to exploit this condition an attacker must be able to send requests to the DHCP server. Two memory leaks have been found and fixed in ISC DHCP. The updated packages have been upgraded to the latest version which is not affected by these issues.
