漏洞描述
中文描述:
Juniper Networks Junos OS和Juniper Networks Junos OS Evolved都是美国瞻博网络(Juniper Networks)公司的产品。Juniper Networks Junos OS是一套专用于该公司的硬件设备的网络操作系统。该操作系统提供了安全编程接口和Junos SDK。Juniper Networks Junos OS Evolved是Junos OS 的升级版系统。 Juniper Networks Junos OS和Juniper Networks Junos OS Evolved存在安全漏洞,该漏洞源于路由协议守护进程存在内存泄漏,可能导致拒绝服务。以下版本受到影响:Juniper Networks Junos OS 23.2R2之前版本、23.4R1-S2和23.4R2之前版本、24.1R2之前版本和Junos OS Evolved 23.2R2-EVO之前版本、23.4R1-S2-EVO和23.4R2-EVO之前版本、24.1R2-EVO之前版本。
英文描述:
A Missing Release of Memory after Effective Lifetime vulnerability in the routing protocol daemon (rpd) Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated attacker controlling an adjacent IS-IS neighbor to send a specific update packet causing a memory leak. Continued receipt and processing of these packets will exhaust all available memory, crashing rpd and creating a Denial of Service (DoS) condition. Memory usage can be monitored through the use of the 'show task memory detail' command. For example: user@junos> show task memory detail | match ted-infra TED-INFRA-COOKIE 25 1072 28 1184 229 user@junos> show task memory detail | match ted-infra TED-INFRA-COOKIE 31 1360 34 1472 307 This issue affects: Junos OS: * from 23.2 before 23.2R2, * from 23.4 before 23.4R1-S2, 23.4R2, * from 24.1 before 24.1R2; Junos OS Evolved: * from 23.2 before 23.2R2-EVO, * from 23.4 before 23.4R1-S2-EVO, 23.4R2-EVO, * from 24.1 before 24.1R2-EVO. This issue does not affect Junos OS versions before 23.2R1 or Junos OS Evolved versions before 23.2R1-EVO.
