![]() ![]() ![]() The NSD process has to be restarted to restore services. ![]() On an SRX 5000 Series device, when executing a specific command repeatedly, memory is corrupted, which leads to a Flow Processing Daemon (flowd) crash. Juniper Networks Junos OS Evolved * All versions earlier than 21.3R3-S5-EVO * 21.4-EVO versions earlier than 21.4R3-S5-EVO * 22.1-EVO versions earlier than 22.1R3-S4-EVO * 22.2-EVO versions earlier than 22.2R3-S2-EVO * 22.3-EVO versions later than 22.3R1-EVO * 22.4-EVO versions earlier than 22.4R2-S2-EVO, 22.4R3-EVO * 23.1-EVO versions earlier than 23.1R2-EVO * 23.2-EVO versions earlier than 23.2R1-S2-EVO, 23.2R2-EVO.Ī Heap-based Buffer Overflow vulnerability in the Network Services Daemon (NSD) of Juniper Networks Junos OS allows authenticated, low privileged, local attacker to cause a Denial of Service (DoS). This issue affects: Juniper Networks Junos OS * All versions earlier than 20.4R3-S9 * 21.2 versions earlier than 21.2R3-S7 * 21.3 versions earlier than 21.3R3-S5 * 21.4 versions earlier than 21.4R3-S5 * 22.1 versions earlier than 22.1R3-S4 * 22.2 versions earlier than 22.2R3-S2 * 22.3 versions earlier than 22.3R3-S1 * 22.4 versions earlier than 22.4R2-S2, 22.4R3 * 23.1 versions earlier than 23.1R2 * 23.2 versions earlier than 23.2R1-S2, 23.2R2. This issue affects both eBGP and iBGP implementations. This issue requires an attacker to have an established BGP session to a system affected by the issue. This issue only affects devices with NSR enabled. The primary RE is not impacted by this issue and there is no impact on traffic. ![]() Continued receipt of these packets will cause a sustained Denial of Service (DoS) condition in the backup RE. If an attacker sends a specific BGP UPDATE message to the device, this will cause a memory overwrite and therefore an RPD crash and restart in the backup Routing Engine (RE). 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.Ī Heap-based Buffer Overflow vulnerability in the Routing Protocol Daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network based attacker to cause a Denial of Service (DoS). CommonMarker versions prior to 0.23.4 are at risk of an integer overflow vulnerability. ![]()
