CVSS: 7.8EPSS: 0%CPEs: 186EXPL: 0CVE-2018-0022 – Junos OS: Mbuf leak due to processing MPLS packets in VPLS network.
https://notcve.org/view.php?id=CVE-2018-0022
A Junos device with VPLS routing-instances configured on one or more interfaces may be susceptible to an mbuf leak when processing a specific MPLS packet. Approximately 1 mbuf is leaked per each packet processed. The number of mbufs is platform dependent. The following command provides the number of mbufs that are currently in use and maximum number of mbufs that can be allocated on a platform: > show system buffers 2437/3143/5580 mbufs in use (current/cache/total) Once the device runs out of mbufs it will become inaccessible and a restart will be required. This issue only affects end devices, transit devices are not affected. • http://www.securityfocus.com/bid/103740 http://www.securitytracker.com/id/1040790 https://kb.juniper.net/JSA10855 • CWE-400: Uncontrolled Resource Consumption •
CVSS: 8.8EPSS: 0%CPEs: 61EXPL: 0CVE-2018-0021 – Junos OS: Short MacSec keys may allow man-in-the-middle attacks.
https://notcve.org/view.php?id=CVE-2018-0021
If all 64 digits of the connectivity association name (CKN) key or all 32 digits of the connectivity association key (CAK) key are not configured, all remaining digits will be auto-configured to 0. Hence, Juniper devices configured with short MacSec keys are at risk to an increased likelihood that an attacker will discover the secret passphrases configured for these keys through dictionary-based and brute-force-based attacks using spoofed packets. Affected releases are Juniper Networks Junos OS: 14.1 versions prior to 14.1R10, 14.1R9; 14.1X53 versions prior to 14.1X53-D47; 15.1 versions prior to 15.1R4-S9, 15.1R6-S6, 15.1R7; 15.1X49 versions prior to 15.1X49-D100; 15.1X53 versions prior to 15.1X53-D59; 16.1 versions prior to 16.1R3-S8, 16.1R4-S8, 16.1R5; 16.2 versions prior to 16.2R1-S6, 16.2R2; 17.1 versions prior to 17.1R2. Si no se configuran todos los 64 dígitos del nombre de la clave de asociación de conectividad (CNK) o todos los 32 dígitos de la clave de asociación de conectividad (CAK), el resto de dígitos se configurarán automáticamente a 0. Por lo tanto, los dispositivos Juniper configurados con claves MacSec cortas están en riesgo de que sea más probable que un atacante descubra las frases de contraseñas secretas configuradas para estas claves a través de ataques basados en diccionario y de fuerza bruta mediante paquetes suplantados. • http://www.securitytracker.com/id/1040789 https://kb.juniper.net/JSA10854 •
CVSS: 7.5EPSS: 5%CPEs: 72EXPL: 0CVE-2017-3145 – Improper fetch cleanup sequencing in the resolver can cause named to crash
https://notcve.org/view.php?id=CVE-2017-3145
BIND was improperly sequencing cleanup operations on upstream recursion fetch contexts, leading in some cases to a use-after-free error that can trigger an assertion failure and crash in named. Affects BIND 9.0.0 to 9.8.x, 9.9.0 to 9.9.11, 9.10.0 to 9.10.6, 9.11.0 to 9.11.2, 9.9.3-S1 to 9.9.11-S1, 9.10.5-S1 to 9.10.6-S1, 9.12.0a1 to 9.12.0rc1. BIND secuenciaba incorrectamente las operaciones de limpieza en contextos fetch de recursión ascendente, lo que conduce en algunos casos a un error de uso de memoria previamente liberada que puede desencadenar un fallo de aserción y un cierre inesperado en named. Afecta a BIND desde la versión 9.0.0 hasta la versión 9.8.x, desde la versión 9.9.0 hasta la versión 9.9.11, desde la versión 9.10.0 hasta la versión 9.10.6, desde la versión 9.11.0 hasta la versión 9.11.2, desde la versión 9.9.3-S1 hasta la versión 09.9.11-S1, desde la versión 9.10.5-S1 hasta la versión 9.10.6-S1 y desde la 9.12.0a1 hasta la 9.12.0rc1. A use-after-free flaw leading to denial of service was found in the way BIND internally handled cleanup operations on upstream recursion fetch contexts. • http://www.securityfocus.com/bid/102716 http://www.securitytracker.com/id/1040195 https://access.redhat.com/errata/RHSA-2018:0101 https://access.redhat.com/errata/RHSA-2018:0102 https://access.redhat.com/errata/RHSA-2018:0487 https://access.redhat.com/errata/RHSA-2018:0488 https://kb.isc.org/docs/aa-01542 https://lists.debian.org/debian-lts-announce/2018/01/msg00029.html https://security.netapp.com/advisory/ntap-20180117-0003 https://supportportal.juniper.net/s/article/ • CWE-416: Use After Free •
CVSS: 8.8EPSS: 0%CPEs: 78EXPL: 0CVE-2018-0005 – Security Bulletin: Junos OS: MAC move limit configured to drop traffic may forward traffic.
https://notcve.org/view.php?id=CVE-2018-0005
QFX and EX Series switches configured to drop traffic when the MAC move limit is exceeded will forward traffic instead of dropping traffic. This can lead to denials of services or other unintended conditions. Affected releases are Juniper Networks Junos OS: 14.1X53 versions prior to 14.1X53-D40; 15.1X53 versions prior to 15.1X53-D55; 15.1 versions prior to 15.1R7. Los switches de las series QFX y EX configurados para volcar el tráfico cuando se excede el límite de movimiento de MAC redireccionan tráfico en vez de volcarlo. Esto puede provocar denegaciones de servicio (DoS) u otras condiciones no esperadas. • http://www.securitytracker.com/id/1040182 https://kb.juniper.net/JSA10833 • CWE-754: Improper Check for Unusual or Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2018-0007
An unauthenticated network-based attacker able to send a maliciously crafted LLDP packet to the local segment, through a local segment broadcast, may be able to cause a Junos device to enter an improper boundary check condition allowing a memory corruption to occur, leading to a denial of service. Further crafted packets may be able to sustain the denial of service condition. Score: 6.5 MEDIUM (CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) Further, if the attacker is authenticated on the target device receiving and processing the malicious LLDP packet, while receiving the crafted packets, the attacker may be able to perform command or arbitrary code injection over the target device thereby elevating their permissions and privileges, and taking control of the device. Score: 7.8 HIGH (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) An unauthenticated network-based attacker able to send a maliciously crafted LLDP packet to one or more local segments, via LLDP proxy / tunneling agents or other LLDP through Layer 3 deployments, through one or more local segment broadcasts, may be able to cause multiple Junos devices to enter an improper boundary check condition allowing a memory corruption to occur, leading to multiple distributed Denials of Services. These Denials of Services attacks may have cascading Denials of Services to adjacent connected devices, impacts network devices, servers, workstations, etc. • http://www.securitytracker.com/id/1040181 https://kb.juniper.net/JSA10830 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
