CVE-2018-0030 – Junos OS: MPC7/8/9, PTX-FPC3 (FPC-P1, FPC-P2) and PTX1K: Line card may crash upon receipt of specific MPLS packet.
https://notcve.org/view.php?id=CVE-2018-0030
Receipt of a specific MPLS packet may cause MPC7/8/9, PTX-FPC3 (FPC-P1, FPC-P2) line cards or PTX1K to crash and restart. By continuously sending specific MPLS packets, an attacker can repeatedly crash the line cards or PTX1K causing a sustained Denial of Service. Affected releases are Juniper Networks Junos OS with MPC7/8/9 or PTX-FPC3 (FPC-P1, FPC-P2) installed and PTX1K: 15.1F versions prior to 15.1F6-S10; 15.1 versions prior to 15.1R4-S9, 15.1R6-S6, 15.1R7; 16.1 versions prior to 16.1R3-S8, 16.1R4-S9, 16.1R5-S4, 16.1R6-S3, 16.1R7; 16.1X65 versions prior to 16.1X65-D46; 16.2 versions prior to 16.2R1-S6, 16.2R2-S5, 16.2R3; 17.1 versions prior to 17.1R1-S7, 17.1R2-S7, 17.1R3; 17.2 versions prior to 17.2R1-S4, 17.2R2-S4, 17.2R3; 17.2X75 versions prior to 17.2X75-D70, 17.2X75-D90; 17.3 versions prior to 17.3R1-S4, 17.3R2, 17.4 versions prior to 17.4R1-S2, 17.4R2. Refer to KB25385 for more information about PFE line cards. La recepción de un paquete MPLS específico podría provocar que las tarjetas de línea MPC7/8/9, PTX-FPC3 (FPC-P1, FPC-P2) o PTX1K se cierre inesperadamente y se reinicie. • http://www.securitytracker.com/id/1041325 https://kb.juniper.net/JSA10864 https://kb.juniper.net/KB25385 • CWE-400: Uncontrolled Resource Consumption •
CVE-2018-0026 – Junos OS: Stateless IP firewall filter rules stop working as expected after reboot or upgrade
https://notcve.org/view.php?id=CVE-2018-0026
After Junos OS device reboot or upgrade, the stateless firewall filter configuration may not take effect. This issue can be verified by running the command: user@re0> show interfaces <interface_name> extensive | match filters" CAM destination filters: 0, CAM source filters: 0 Note: when the issue occurs, it does not show the applied firewall filter. The correct output should show the applied firewall filter, for example: user@re0> show interfaces <interface_name> extensive | match filters" CAM destination filters: 0, CAM source filters: 0 Input Filters: FIREWAL_FILTER_NAME-<interface_name> This issue affects firewall filters for every address family. Affected releases are Juniper Networks Junos OS: 15.1R4, 15.1R5, 15.1R6 and SRs based on these MRs. 15.1X8 versions prior to 15.1X8.3. Tras un reinicio o actualización del dispositivo Junos OS, la configuración del filtro del firewall sin estado podría no surtir efecto. • http://www.securityfocus.com/bid/104720 http://www.securitytracker.com/id/1041315 https://kb.juniper.net/JSA10859 •
CVE-2018-0027 – Junos OS: Receipt of malformed RSVP packet may lead to RPD denial of service
https://notcve.org/view.php?id=CVE-2018-0027
Receipt of a crafted or malformed RSVP PATH message may cause the routing protocol daemon (RPD) to hang or crash. When RPD is unavailable, routing updates cannot be processed which can lead to an extended network outage. If RSVP is not enabled on an interface, then the issue cannot be triggered via that interface. This issue only affects Juniper Networks Junos OS 16.1 versions prior to 16.1R3. This issue does not affect Junos releases prior to 16.1R1. • http://www.securityfocus.com/bid/104721 http://www.securitytracker.com/id/1041318 https://kb.juniper.net/JSA10861 • CWE-20: Improper Input Validation •
CVE-2018-0031 – Junos OS: Receipt of specially crafted UDP packets over MPLS may bypass stateless IP firewall rules
https://notcve.org/view.php?id=CVE-2018-0031
Receipt of specially crafted UDP/IP packets over MPLS may be able to bypass a stateless firewall filter. The crafted UDP packets must be encapsulated and meet a very specific packet format to be classified in a way that bypasses IP firewall filter rules. The packets themselves do not cause a service interruption (e.g. RPD crash), but receipt of a high rate of UDP packets may be able to contribute to a denial of service attack. This issue only affects processing of transit UDP/IP packets over MPLS, received on an interface with MPLS enabled. • http://www.securitytracker.com/id/1041326 https://kb.juniper.net/JSA10865 • CWE-400: Uncontrolled Resource Consumption •
CVE-2018-0032 – Junos OS: RPD crash when receiving a crafted BGP UPDATE
https://notcve.org/view.php?id=CVE-2018-0032
The receipt of a crafted BGP UPDATE can lead to a routing process daemon (RPD) crash and restart. Repeated receipt of the same crafted BGP UPDATE can result in an extended denial of service condition for the device. This issue only affects the specific versions of Junos OS listed within this advisory. Earlier releases are unaffected by this vulnerability. This crafted BGP UPDATE does not propagate to other BGP peers. • http://www.securitytracker.com/id/1041337 https://kb.juniper.net/JSA10866 • CWE-20: Improper Input Validation •
