Cisco Warns of Critical Flaw in Teleconferencing Gear

Cisco Systems is warning customers of a critical vulnerability affecting three of its TelePresence MCU platform models. The flaw could give attackers the ability to remotely execute code on impacted systems or create conditions favorable to a denial-of-service DoS attack. According to an advisory...

CVE-2016-10142

It was discovered that a remote attacker could leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow in scenarios in which actual fragmentation of packets is not needed and could subsequently perform any type of a fragmentation-based attack...
