CVSS: 5.9EPSS: 0%CPEs: 215EXPL: 0CVE-2018-0019 – Junos: Denial of service vulnerability in SNMP MIB-II subagent daemon (mib2d).
https://notcve.org/view.php?id=CVE-2018-0019
A vulnerability in Junos OS SNMP MIB-II subagent daemon (mib2d) may allow a remote network based attacker to cause the mib2d process to crash resulting in a denial of service condition (DoS) for the SNMP subsystem. While a mib2d process crash can disrupt the network monitoring via SNMP, it does not impact routing, switching or firewall functionalities. SNMP is disabled by default on devices running Junos OS. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D76; 12.3 versions prior to 12.3R12-S7, 12.3R13; 12.3X48 versions prior to 12.3X48-D65; 14.1 versions prior to 14.1R9; 14.1X53 versions prior to 14.1X53-D130; 15.1 versions prior to 15.1F2-S20, 15.1F6-S10, 15.1R7; 15.1X49 versions prior to 15.1X49-D130; 15.1X53 versions prior to 15.1X53-D233, 15.1X53-D471, 15.1X53-D472, 15.1X53-D58, 15.1X53-D66; 16.1 versions prior to 16.1R5-S3, 16.1R7; 16.1X65 versions prior to 16.1X65-D47; 16.1X70 versions prior to 16.1X70-D10; 16.2 versions prior to 16.2R1-S6, 16.2R2-S5, 16.2R3; 17.1 versions prior to 17.1R2-S6, 17.1R3; Una vulnerabilidad en el demonio de subagente SNMP MIB-II (mib2d) de Junos OS podría permitir que un atacante remoto en red provoque que el proceso mib2d se cierre inesperadamente, lo que resulta en una condición de denegación de servicio (DoS) para el subsistema SNMP. Aunque un cierre inesperado del proceso mib2d puede interrumpir la monitorización de red mediante SNMP, no impacta sobre las funcionalidades de enrutamiento, switching o firewall. • http://www.securitytracker.com/id/1040787 https://kb.juniper.net/JSA10847 • CWE-20: Improper Input Validation •
CVSS: 7.5EPSS: 0%CPEs: 85EXPL: 0CVE-2018-0018 – SRX Series: A crafted packet may lead to information disclosure and firewall rule bypass during compilation of IDP policies.
https://notcve.org/view.php?id=CVE-2018-0018
On SRX Series devices during compilation of IDP policies, an attacker sending specially crafted packets may be able to bypass firewall rules, leading to information disclosure which an attacker may use to gain control of the target device or other internal devices, systems or services protected by the SRX Series device. This issue only applies to devices where IDP policies are applied to one or more rules. Customers not using IDP policies are not affected. Depending on if the IDP updates are automatic or not, as well as the interval between available updates, an attacker may have more or less success in performing reconnaissance or bypass attacks on the victim SRX Series device or protected devices. ScreenOS with IDP is not vulnerable to this issue. • http://www.securityfocus.com/bid/103748 http://www.securitytracker.com/id/1040786 https://kb.juniper.net/JSA10846 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
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: 7.8EPSS: 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: 7.5EPSS: 9%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 •
