Summary
An Improper Check or Handling of Exceptional Conditions vulnerability in the UTM (Unified Threat Management) Web-Filtering feature of Juniper Networks Junos OS on SRX Series causes a jbuf memory leak to occur when accessing certain websites, eventually leading to a Denial of Service (DoS) condition. Service restoration is only possible by rebooting the system.
The jbuf memory leak only occurs in SSL Proxy and UTM Web-Filtering configurations. Other products, platforms, and configurations are not affected by this vulnerability.
This issue affects Juniper Networks Junos OS on SRX Series:
22.2 versions prior to 22.2R3;
22.3 versions prior to 22.3R2-S1, 22.3R3;
22.4 versions prior to 22.4R1-S2, 22.4R2.
This issue does not affect Juniper Networks Junos OS versions prior to 22.2R2.
