Vulnerability Title
Junos OS: SRX4000 Series, SRX5000 Series and MX Series with SPC3: With application services configured, high session churn causes memory leak which will ultimately impact traffic
来源: CVE Program / CVE List V5
Vulnerability Description
A Missing Release of Memory after Effective Lifetime vulnerability in the packet forwarding engine (PFE) of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause a complete Denial-of-Service (DoS). On SRX4000 Series, and SRX5000 Series with SPC3, and MX Series with SPC3, when one or more specific application services like ALGs, IDP/DPI, APPID, SECINTEL, AAMW or AppQoE are configured, a high connections per second churn will cause PFE memory to leak. If the memory is exhausted traffic processing will be impacted. Use the CLI command show security monitoring to monitor the memory utilization of the PFEs on the FPCs. This issue affects Junos OS on SRX Series and MX Series: * 23.4 versions from 23.4R2-S3 before 23.4R2-S7; * 24.2 versions from 24.2R2 before 24.2R2-S3; * 24.4 versions before 24.4R2-S3; * 25.2 versions before 25.2R1-S2, 25.2R2.
