The memory usage can be monitored using the below command. This memory leak, over time, will lead to an rpd crash and restart. On all Junos OS and Junos OS Evolved platforms, when traffic engineering is enabled for OSPF or ISIS, and a link flaps, a patroot memory leak is observed. This issue does not affect Junos OS versions earlier than 20.4R3-S7.Ī Missing Release of Memory after Effective Lifetime vulnerability in Routing Protocol Daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause an rpd crash, leading to Denial of Service (DoS). show chassis routing-engine no-forwarding show system memory | no-more This issue affects: Juniper Networks Junos OS * 21.2 versions earlier than 21.2R3-S5 * 21.3 versions earlier than 21.3R3-S4 * 21.4 versions earlier than 21.4R3-S4 * 22.1 versions earlier than 22.1R3-S2 * 22.2 versions earlier than 22.2R3-S2 * 22.3 versions earlier than 22.3R2-S1, 22.3R3 * 22.4 versions earlier than 22.4R1-S2, 22.4R2. The memory usage can be monitored using the below commands. Note: NSR is not supported on the SRX Series and is therefore not affected by this vulnerability. A manual reboot of the system will restore the services. On all Junos OS platforms, when NSR is enabled, a BGP flap will cause memory leak. This vulnerability can result in possibly unauthenticated remote attackers to cause heap memory corruption, potentially leading to an information leak or remote code execution, via parsing tables with marker rows that contain more than UINT16_MAX columns.Īn Incomplete Cleanup vulnerability in Nonstop active routing (NSR) component of Juniper Networks Junos OS allows an adjacent, unauthenticated attacker to cause memory leak leading to Denial of Service (DoS). Openvswitch 2.17.8 was discovered to contain a memory leak via the function xmalloc_ in openvswitch-2.17.8/lib/util.c.ĬommonMarker versions prior to 0.23.4 are at risk of an integer overflow vulnerability.
