Description Martin Prpič 2016-03-10 08:19:49 EST

A heap based buffer overflow was discovered in udhcpc when parsing IPv6 Rapid Deployment DHCP option. An attacker could send a maliciously crafted packet as an answer to a DHCP request, to overwrite the heap, resulting in crash or remote code execution.
