Problem description
Multiple vulnerabilities has been discovered and corrected in ISC DHCP:
An error in the handling of malformed client identifiers can cause
a DHCP server running affected versions (see Impact) 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 (CVE-2012-3571).
Two memory leaks have been found and fixed in ISC DHCP. Both are
reproducible when running in DHCPv6 mode (with the -6 command-line
argument.) The first leak is confirmed to only affect servers
operating in DHCPv6 mode, but based on initial code analysis the
second may theoretically affect DHCPv4 servers (though this has not
been demonstrated.) (CVE-2012-3954).
The updated packages have been patched to correct these issues.
