漏洞描述信息
在Cisco会议服务器(CMS)2.1.4中实现H.264协议的一个漏洞可能导致未验证的远程攻击者在一个受影响的系统上造成拒绝服务(DoS)情况。该漏洞的存在是因为受影响的应用没有正确验证分割单元(FU-A)协议帧。攻击者可以通过通过受影响的应用发送精心构造的H.264 FU-A帧来利用此漏洞。成功利用此漏洞可能导致攻击者因系统上 CMS媒体进程意外重启而在受影响的系统上造成DoS情况。尽管CMS平台继续运行,且只重新启动受影响的单个 CMS媒体进程,但某些用户的媒体流量可能短暂中断。CiscoBug ID: CSCve10131。

漏洞描述信息
A vulnerability in the implementation of the H.264 protocol in Cisco Meeting Server (CMS) 2.1.4 could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected system. The vulnerability exists because the affected application does not properly validate Fragmentation Unit (FU-A) protocol packets. An attacker could exploit this vulnerability by sending a crafted H.264 FU-A packet through the affected application. A successful exploit could allow the attacker to cause a DoS condition on the affected system due to an unexpected restart of the CMS media process on the system. Although the CMS platform continues to operate and only the single, affected CMS media process is restarted, a brief interruption of media traffic for certain users could occur.
