Vulnerability Description
A res_pjsip_session crash was discovered in Asterisk Open Source 13.x before 13.37.1, 16.x before 16.14.1, 17.x before 17.8.1, and 18.x before 18.0.1. and Certified Asterisk before 16.8-cert5. Upon receiving a new SIP Invite, Asterisk did not return the created dialog locked or referenced. This caused a gap between the creation of the dialog object, and its next use by the thread that created it. Depending on some off-nominal circumstances and timing, it was possible for another thread to free said dialog in this gap. Asterisk could then crash when the dialog object, or any of its dependent objects, were dereferenced or accessed next by the initial-creation thread. Note, however, that this crash can only occur when using a connection-oriented protocol (e.g., TCP or TLS, but not UDP) for SIP transport. Also, the remote client must be authenticated, or Asterisk must be configured for anonymous calling.

Vulnerability Description
Digium Asterisk Open Source是美国Digium公司的一套开源的电话交换机（PBX）系统软件。该软件支持语音信箱、多方语音会议、交互式语音应答(IVR)等。 Asterisk Open Source 存在安全漏洞，该漏洞源于在接收到新的SIP邀请时，没有返回已锁定或引用的已创建的对话框。这导致了dialog对象的创建和创建它的线程的下一次使用之间的差距。根据一些非正常的环境和时间，另一个线程可以在这个间隙中释放对话框。可能会在对话框对象或其任何依赖ob时崩溃。以下产品及版本受到影响
