Vulnerability Title
OpenSIPS: Denial of Service in SDP bandwidth parsing via QoS SDP cloning
Vulnerability Description
OpenSIPS is a Session Initiation Protocol (SIP) server implementation. Versions prior to 3.6.6 and 4.0.0-rc1 contain a denial of service vulnerability in the SDP bandwidth-line parsing logic. A SIP request with Content-Type: application/sdp and a malformed session-level SDP bandwidth line missing the required colon delimiter can corrupt parsed SDP bandwidth metadata. When a route or module subsequently clones the corrupted SDP state, as occurs with dialog and QoS processing, the OpenSIPS worker process crashes. An unauthenticated remote attacker can therefore trigger a crash in any configuration whose routing script parses attacker-controlled SDP and applies dialog/QoS processing. This issue has been fixed in versions 3.6.6 and 4.0.0-rc1.

Vulnerability Title
OpenSIPS 输入验证错误漏洞
Vulnerability Description
OpenSIPS是OpenSIPS组织开源的一个 GPL 许可的 SIP 服务器实现。 OpenSIPS 3.6.6之前版本和4.0.0-rc1之前版本存在安全漏洞,该漏洞源于SDP带宽行解析逻辑存在缺陷,格式错误的SDP带宽行可能损坏解析的带宽元数据,导致worker进程崩溃,未经身份验证的远程攻击者可利用该漏洞触发拒绝服务。
