Vulnerability Description
The IAX2 channel driver (chan_iax2) for Asterisk 1.2.x before 1.2.9 and 1.0.x before 1.0.11 allows remote attackers to cause a denial of service (crash) and execute arbitrary code via truncated IAX 2 (IAX2) video frames, which bypasses a length check and leads to a buffer overflow involving negative length check. NOTE: the vendor advisory claims that only a DoS is possible, but the original researcher is reliable.

Asterisk IAX2 远程内存破坏漏洞
Vulnerability Description
Asterisk是开放源码的软件PBX，支持各种VoIP协议和设备。 Asterisk的IAX消息解析的实现上存在内存破坏漏洞，远程攻击者可能利用此漏洞在服务器上执行任意指令。 IAX协议的所有通讯都依赖于4569/UDP端口。协议使用15位的标识号在同一UDP端口上多路传输几个IAX2流。IAX2消息被称为帧，Asterisk源码包的iax2.h头文件中定义了几个基本的帧类型。 IAX2完整帧使用如下的12字节首部： struct ast_iax2_full_hdr { unsigned short s
