On QFX5000 Series and EX4600 switches, a high rate of Ethernet pause frames or an ARP packet storm received on the management interface (fxp0) can cause egress interface congestion, resulting in routing protocol packet drops, such as BGP, leading to peering flaps. The following log message may also be displayed: fpc0 dcbcm_check_stuck_buffers: Buffers are stuck on queue 7 of port 45 This issue only affects the QFX5000 Series products (QFX5100, QFX5110, QFX5200, QFX5210) and the EX4600 switch. No other platforms are affected by this issue. Affected releases are Juniper Networks Junos OS: 14.1X53 versions prior to 14.1X53-D47 on QFX5000 Series and EX4600; 15.1 versions prior to 15.1R7, 15.1R8 on QFX5000 Series and EX4600; 15.1X53 versions prior to 15.1X53-D233 on QFX5000 Series and EX4600; 16.1 versions prior to 16.1R7 on QFX5000 Series and EX4600; 16.2 versions prior to 16.2R3 on QFX5000 Series and EX4600; 17.1 versions prior to 17.1R2-S9, 17.1R3 on QFX5000 Series and EX4600; 17.2 versions prior to 17.2R2-S6, 17.2R3 on QFX5000 Series and EX4600; 17.2X75 versions prior to 17.2X75-D42 on QFX5000 Series and EX4600; 17.3 versions prior to 17.3R3 on QFX5000 Series and EX4600; 17.4 versions prior to 17.4R2 on QFX5000 Series and EX4600; 18.1 versions prior to 18.1R2 on QFX5000 Series and EX4600.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For juniper's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
