dhcp: Reference count overflow in dhcpd allows denial of service

A denial of service flaw was found in the way dhcpd handled reference counting when processing client requests. A malicious DHCP client could use this flaw to trigger a reference count overflow on the server side, potentially causing dhcpd to crash, by sending large amounts of traffic...

dhcp: Buffer overflow in dhclient possibly allowing code execution triggered by malicious server

An out-of-bound memory access flaw was found in the way dhclient processed a DHCP response packet. A malicious DHCP server could potentially use this flaw to crash dhclient processes running on DHCP client machines via a crafted DHCP response packet...

The vulnerability of the DHCP server dhcpd arises from the possibility of overflowing the 32-bit link counter, which can lead to a failure in server operation.

The vulnerability of the DHCP server dhcpd arises from the possibility of overflowing the 32-bit link counter. Exploiting this vulnerability allows a malicious actor, operating remotely, to cause the server to fail by sending a large number of specially crafted DCHP requests...

The vulnerability of the receive_packet function in the Android operating system allows a hacker to execute arbitrary code.

The vulnerability of the receivepacket function in the libnetutils/packet.c file of the Android operating system is related to incorrect checking of the size of the DHCP response. Exploiting this vulnerability could allow a malicious actor, operating remotely, to execute arbitrary code within the...
