The vulnerability is due to improper size validation when reassembling fragmented IPv4 or IPv6 packets. An attacker could exploit this vulnerability by sending crafted IPv4 or IPv6 fragments to a port receiving content in Passthrough content mode. An exploit could allow the attacker to overflow a buffer. If successful, the attacker could execute arbitrary code or cause a DoS condition on the affected system. Cisco TelePresence MCU platforms TelePresence MCU 5300 Series, TelePresence MCU MSE 8510 and TelePresence MCU 4500 are affected when running software version 4.3(1.68) or later configured for Passthrough content mode. Cisco has released software updates that address this vulnerability. Workarounds that address this vulnerability are not available, but mitigations are available.

La vulnerabilidad se debe a una validaci\u00f3n de tama\u00f1o incorrecta al reensamblar paquetes IPv4 o IPv6 fragmentados. Un atacante podr\u00eda explotar esta vulnerabilidad mediante el env\u00edo de fragmentos IPv4 o IPv6 a un puerto que reciba contenido en modo de contenido Passthrough. Un exploit podr\u00eda permitir al atacante desbordar un b\u00fafer.
