FreeBSD : isc-dhcp -- Multiple vulnerabilities (2040c7f5-1e3a-11e8-8ae9-0050569f0b83)
Medium Nessus Plugin ID 107126
SynopsisThe remote FreeBSD host is missing one or more security-related updates.
DescriptionISC reports :
Failure to properly bounds check a buffer used for processing DHCP options allows a malicious server (or an entity masquerading as a server) to cause a buffer overflow (and resulting crash) in dhclient by sending a response containing a specially constructed options section.
A malicious client which is allowed to send very large amounts of traffic (billions of packets) to a DHCP server can eventually overflow a 32-bit reference counter, potentially causing dhcpd to crash.
SolutionUpdate the affected packages.
