漏洞描述
中文描述:
Cisco Meeting Server(前称Acano Conferencing Server,CMS)是美国思科(Cisco)公司的一套包含音频、视频的会议服务器软件。 Cisco Meeting Server中的H.26解码器函数存在拒绝服务漏洞。远程攻击者可通过发送畸形的H.264帧利用该漏洞造成拒绝服务(媒体进程重启)。
英文描述:
A vulnerability in the H.264 decoder function of Cisco Meeting Server could allow an unauthenticated, remote attacker to cause a Cisco Meeting Server media process to restart unexpectedly when it receives an illegal H.264 frame. The vulnerability is triggered by an H.264 frame that has an invalid picture parameter set (PPS) value. An attacker could exploit this vulnerability by sending a malformed H.264 frame to the targeted device. An exploit could allow the attacker to cause a denial of service (DoS) condition because the media process could restart. The media session should be re-established within a few seconds, during which there could be a brief interruption in service. Cisco Bug IDs: CSCvg12559.
