Title

F5 BIG-IP Next TMM内存资源管理漏洞

Description

F5 BIG-IP是F5公司的一款集成了网络流量编排、负载均衡、智能DNS，远程接入策略管理等功能的应用交付平台。 BIG-IP Next的TMM模块存在内存资源管理漏洞，该漏洞产生的原因是在通过声明式API在虚拟服务器上配置iRule后，重新实例化时清理过程会导致TMM内存资源利用率增加。攻击者可利用该漏洞导致系统性能下降，最终可能引发拒绝服务。

Title

TMM Vulnerability

Summary

When an iRule is configured on a virtual server via the declarative API, upon re-instantiation, the cleanup process can cause an increase in the Traffic Management Microkernel (TMM) memory resource utilization. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
