| Improper Following of a Certificate's Chain of Trust vulnerability in Erlang OTP public_key (pubkey_cert module) allows a non-CA certificate to be accepted as an intermediate issuer, enabling certificate chain forgery.
In lib/public_key/src/pubkey_cert.erl, pubkey_cert:validate_extensions/7 contains two flaws that together allow a certificate with basicConstraints cA:false and no keyUsage extension to be used as an intermediate issuer in a chain passed to public_key:pkix_path_validation/3: the cA:false clause recurses into the remaining extensions without rejecting the certificate when it is in issuer position, and the keyUsage check only fires when the extension is present, so a certificate lacking keyUsage entirely bypasses the keyCertSign enforcement.
Any party holding an end-entity certificate with basicConstraints cA:false and no keyUsage extension, issued by any CA in the victim's trust store, can use that certificate's private key to sign forged leaf certificates for arbitrary identities. public_key:pkix_path_validation/3 accepts the resulting chain, and by extension every TLS or mTLS endpoint built on the OTP ssl application that relies on the default verifier is affected, including server identity verification on the client side and client certificate verification on mTLS servers.
This issue affects OTP from OTP 17.0 before OTP 27.3.4.19, OTP 28.5.0.8, and OTP 29.1.2, corresponding to public_key from 0.22 before 1.17.1.7, 1.20.3.6, and 1.21.8. Whether OTP before OTP 17.0, corresponding to public_key before 0.22, is affected is unknown. |
| An Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability in the phone-home daemon (phcd) of Juniper Networks Junos OS and Junos OS Evolved on EX Series, SRX Series, and QFX Series allows an adjacent unauthenticated attacker to execute arbitrary commands with root privileges via a rogue DHCP server. |
| Improper Validation of Consistency within Input vulnerability in Erlang OTP ssl (tls_handshake_1_3, ssl_handshake and tls_client_ticket_store modules) allows a malicious TLS 1.3 server to cause a denial of service of the ssl application on the client node.
The TLS 1.3 client decodes the extensions of a NewSessionTicket message as if they came from EncryptedExtensions. It therefore accepts a 0-length early_data extension, a form that is only valid in ClientHello and EncryptedExtensions. With {session_tickets, auto}, the client stores the ticket in the node-global tls_client_ticket_store. On the next automatic resumption, tls_handshake_1_3:get_max_early_data/1 crashes the store with a case_clause. Repeated crashes can exceed the restart intensity of the ssl supervisors, which use the rest_for_one strategy, and take down ssl for all connections on the node.
This issue affects OTP from OTP 23.3 before OTP 27.3.4.19, OTP 28.5.0.8, and OTP 29.1.2, corresponding to ssl from 10.3 before 11.2.12.14, 11.6.0.7, and 11.7.8. |
| A Stack-based Buffer Overflow vulnerability in the jdhcpd process of Juniper Networks Junos OS allows an unauthenticated adjacent attacker to cause a denial of service via a DHCP client response. The issue affects DHCP client operation and can interrupt related DHCP, relay, and zero-touch-provisioning services. |
| An Out-of-bounds Read vulnerability in the cfmd process of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated adjacent-network attacker to crash the daemon and disclose limited process memory via a specific CFM Message sent to a configured interface. |
| Uncontrolled Resource Consumption vulnerability in mtrudel bandit allows an unauthenticated remote attacker to pin HTTP/2 stream processes indefinitely via a trickle of small WINDOW_UPDATE frames. A stream whose response outruns the connection or stream send window blocks until the peer grants more window, and each block carries a 15 second deadline. Both deadlines restart whenever the peer makes partial progress. Bandit.HTTP2.Connection.finish_data/5 re-queues a partially advanced send in pending_sends with a fresh expires_at, so every WINDOW_UPDATE on stream 0, and every SETTINGS frame, resets the clock. Bandit.HTTP2.Stream.send_data/3 recurses on each stream WINDOW_UPDATE and re-arms a fresh after read_timeout. A peer that grants a few bytes every few seconds keeps the blocked stream process, its Plug state and any resource it holds mid-response alive for as long as it keeps dripping, and repeats this across streams and connections to exhaust server processes and memory.
The two paths are independent. The stream-level block is reached on its own by widening the connection window with a large WINDOW_UPDATE on stream 0 and shrinking the per-stream window with a small SETTINGS_INITIAL_WINDOW_SIZE, so closing only the connection-level path leaves it exploitable.
This issue affects bandit: from 1.4.0 onward. |
| A Stack-based Buffer Overflow vulnerability in the cfmd process of Juniper Networks Junos OS on MX Series and Junos OS Evolved on PTX Series platforms allows an unauthenticated adjacent-network attacker to execute arbitrary code as root or cause denial of service via a specific CFM Message sent to a configured down-MEP with enhanced CFM mode enabled. |
| An Improper Release of Memory Before Removing Last Reference vulnerability in the l2ald process of Juniper Networks Junos OS and Junos OS Evolved on QFX5K-family platforms allows a configured EVPN peer to cause a denial of service through memory exhaustion via EVPN-VXLAN active-active multihoming route processing. |

| A Stack-based Buffer Overflow vulnerability in the l2cpd daemon of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated adjacent attacker to cause a denial of service in Layer 2 control-plane processing via LLDP packets received on an interface configured for LLDP. Repeated triggering may disrupt LLDP and other Layer 2 control protocols across the device. |
| A Stack-based Buffer Overflow vulnerability in the l2cpd process of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent unauthenticated attacker to cause a denial of service or execute arbitrary code with root privileges via LLDP traffic received on an interface with Unified Access Policy enabled. |
| An Allocation of Resources Without Limits or Throttling vulnerability in the l2cpd process of Juniper Networks Junos OS allows an adjacent unauthenticated attacker to cause a denial of service and l2cpd restart via FNP-enabled Layer 2 interfaces. The issue is triggered when the FNP feature is enabled on a VPLS routing instance with VLAN-VPLS encapsulation enabled.
This issue affects all platforms except the PTX Series and SRX Series. |
