      "summary": "A Missing Release of Memory after Effective Lifetime vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a local, low privileged user to cause an impact to the availability of the device.\n\nWhen RIB sharding is enabled and a user executes one of several routing related 'show' commands, a certain amount of memory is leaked. When all available memory has been consumed rpd will crash and restart.\n\nThe leak can be monitored with the CLI command:\n\n\n\nshow task memory detail | match task_shard_mgmt_cookie\n\n\n\nwhere the allocated memory in bytes can be seen to continuously increase with each exploitation.\n\n\n\nThis issue affects:\n\nJunos OS:\n\n  *  all versions before 21.2R3-S9,\n  *  21.4 versions before 21.4R3-S11,\n  *  22.2 versions before 22.2R3-S7,\n  *  22.4 versions before 22.4R3-S7,\n  *  23.2 versions before 23.2R2-S4, \n  *  23.4 versions before 23.4R2-S4,\n  *  24.2 versions before 24.2R2,\n  *  24.4 versions before 24.4R1-S2, 24.4R2;\n\n\nJunos OS Evolved:\n\n  *  all versions before 22.2R3-S7-EVO\n  *  22.4-EVO versions before 22.4R3-S7-EVO,\n  *  23.2-EVO versions before 23.2R2-S4-EVO,\n  *  23.4-EVO versions before 23.4R2-S4-EVO,\n  *  24.2-EVO versions before 24.2R2-EVO, \n  *  24.4-EVO versions before 24.4R2-EVO.",
