Juniper SIRT (JSA) via NVD
Juniper's advisory portal (kb.juniper.net) is a login-walled Salesforce app, so VulniPulse ingests Juniper SIRT (JSA) advisories from NVD, filtered to Juniper's own CNA (sirt@juniper.net) — official, machine-readable data with the affected Junos releases in each description. Junos on SRX/MX/EX/QFX and Junos Space are the common targets.

High [CVE-2025-60003] Buffer Over-read vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved
A Buffer Over-read 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). When an affected device receives a BGP update with a set of specific optional transitive attributes over an established peering session, rpd will crash and restart when attempting to advertise the received information to another peer. This issue can only happen if one or both of the BGP peers of the receiving session are non-4-byte-AS capable as determined from the advertised capabilities during BGP session establishment. Junos OS and Junos OS Evolved default behavior is 4-byte-AS capable unless this has been specifically disabled by configuring: [ protocols bgp... disable-4byte-as ] Established BGP sessions can be checked by executing: show bgp neighbor | match "4 byte AS" This issue affects: - all versions before 22.4R3-S8, - 23.2 versions before 23.2R2-S5, - 23.4 versions before 23.4R2-S6, Affected products named by the advisory: EX.
High [CVE-2025-59960] Junos: Improper Check for Unusual or Exceptional Conditions vulnerability in the Juniper DHCP service (jdhcpd) of Juniper Networks…
An Improper Check for Unusual or Exceptional Conditions vulnerability in the Juniper DHCP service (jdhcpd) of Juniper Networks Junos OS and Junos OS Evolved allows a DHCP client in one subnet to exhaust the address pools of other subnets, leading to a Denial of Service (DoS) on the downstream DHCP server. By default, the DHCP relay agent inserts its own Option 82 information when forwarding client requests, optionally replacing any Option 82 information provided by the client. When a specific DHCP DISCOVER is received in 'forward-only' mode with Option 82, the device should drop the message unless 'trust-option82' is configured. Instead, the DHCP relay forwards these packets to the DHCP server unmodified, which uses up addresses in the DHCP server's address pool, ultimately leading to address pool exhaustion. This issue affects Junos OS: - all versions before 21.2R3-S10, - from 21.4 before 21.4R3-S12, - from 23.2 before 23.2R2-S5, - from 23.4 before 23.4R2-S6, - all versions of 22.2-EVO, - from 22.4 before 22.4R3-S8-EVO, Affected products named by the advisory: EX.
