CVE-2017-2344 – Junos: Buffer overflow in sockets library
https://notcve.org/view.php?id=CVE-2017-2344
A routine within an internal Junos OS sockets library is vulnerable to a buffer overflow. Malicious exploitation of this issue may lead to a denial of service (kernel panic) or be leveraged as a privilege escalation through local code execution. The routines are only accessible via programs running on the device itself, and veriexec restricts arbitrary programs from running on Junos OS. There are no known exploit vectors utilizing signed binaries shipped with Junos OS itself. Affected releases are Juniper Networks Junos OS 12.1X46 prior to 12.1X46-D67; 12.3X48 prior to 12.3X48-D51, 12.3X48-D55; 13.3 prior to 13.3R10-S2; 14.1 prior to 14.1R2-S10, 14.1R8-S4, 14.1R9; 14.1X50 prior to 14.1X50-D185; 14.1X53 prior to 14.1X53-D122, 14.1X53-D45, 14.1X53-D50; 14.2 prior to 14.2R4-S9, 14.2R7-S7, 14.2R8; 15.1 prior to 15.1F2-S18, 15.1F6-S7, 15.1R4-S8, 15.1R5-S5, 15.1R6-S1, 15.1R7; 15.1X49 prior to 15.1X49-D100; 15.1X53 prior to 15.1X53-D231, 15.1X53-D47, 15.1X53-D48, 15.1X53-D57, 15.1X53-D64, 15.1X53-D70; 16.1 prior to 16.1R3-S4, 16.1R4-S3, 16.1R4-S4, 16.1R5; 16.2 prior to 16.2R2; 17.1 prior to 17.1R1-S3, 17.1R2; 17.2 prior to 17.2R1-S1, 17.2R2; 17.2X75 prior to 17.2X75-D30. • http://www.securityfocus.com/bid/99556 http://www.securitytracker.com/id/1038896 https://kb.juniper.net/JSA10792 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2017-2347 – Junos: Denial of Service vulnerability in rpd daemon
https://notcve.org/view.php?id=CVE-2017-2347
A denial of service vulnerability in rpd daemon of Juniper Networks Junos OS allows a malformed MPLS ping packet to crash the rpd daemon if MPLS OAM is configured. Repeated crashes of the rpd daemon can result in an extended denial of service condition for the device. The affected releases are Junos OS 12.3X48 prior to 12.3X48-D50, 12.3X48-D55; 13.3 prior to 13.3R10; 14.1 prior to 14.1R4-S13, 14.1R8-S3, 14.1R9; 14.1X53 prior to 14.1X53-D42, 14.1X53-D50; 14.2 prior to 14.2R4-S8, 14.2R7-S6, 14.2R8; 15.1 prior to 15.1F2-S14, 15.1F5-S7, 15.1F6-S4, 15.1F7, 15.1R4-S7, 15.1R5-S1, 15.1R6; 15.1X49 prior to 15.1X49-D100; 15.1X53 prior to 15.1X53-D105, 15.1X53-D47, 15.1X53-D62, 15.1X53-D70; 16.1 prior to 16.1R3-S3, 16.1R4. No other Juniper Networks products or platforms are affected by this issue. Una vulnerabilidad de denegación de servicio en el demonio rpd de Juniper Networks Junos OS, permite que un paquete de ping MPLS malformado bloquee el demonio rpd si MPLS OAM está configurado. • http://www.securityfocus.com/bid/100236 http://www.securitytracker.com/id/1038892 https://kb.juniper.net/JSA10795 • CWE-20: Improper Input Validation •
CVE-2017-2315
https://notcve.org/view.php?id=CVE-2017-2315
On Juniper Networks EX Series Ethernet Switches running affected Junos OS versions, a vulnerability in IPv6 processing has been discovered that may allow a specially crafted IPv6 Neighbor Discovery (ND) packet destined to an EX Series Ethernet Switch to cause a slow memory leak. A malicious network-based packet flood of these crafted IPv6 NDP packets may eventually lead to resource exhaustion and a denial of service. The affected Junos OS versions are: 12.3 prior to 12.3R12-S4, 12.3R13; 13.3 prior to 13.3R10; 14.1 prior to 14.1R8-S3, 14.1R9; 14.1X53 prior ro 14.1X53-D12, 14.1X53-D40; 14.1X55 prior to 14.1X55-D35; 14.2 prior to 14.2R6-S4, 14.2R7-S6, 14.2R8; 15.1 prior to 15.1R5; 16.1 before 16.1R3; 16.2 before 16.2R1-S3, 16.2R2. 17.1R1 and all subsequent releases have a resolution for this vulnerability. En Switches EX Series Ethernet de Juniper Networks ejecutando las versiones afectadas del Junos OS, se detectó una vulnerabilidad en el procesamiento IPv6 que puede permitir que un paquete Neighbor Discovery (ND) de IPv6 especialmente diseñado destinado hacia un Switch EX Series Ethernet cause una pérdida de memoria lenta. Una inundación de paquetes maliciosos sobre la red de estos paquetes NDP de IPv6 diseñados puede eventualmente conllevar al agotamiento de recursos y a una denegación de servicio. • http://www.securityfocus.com/bid/97615 http://www.securitytracker.com/id/1038253 https://kb.juniper.net/JSA10781 • CWE-772: Missing Release of Resource after Effective Lifetime •
CVE-2017-2312
https://notcve.org/view.php?id=CVE-2017-2312
On Juniper Networks devices running Junos OS affected versions and with LDP enabled, a specific LDP packet destined to the RE (Routing Engine) will consume a small amount of the memory allocated for the rpd (routing protocol daemon) process. Over time, repeatedly receiving this type of LDP packet(s) will cause the memory to exhaust and the rpd process to crash and restart. It is not possible to free up the memory that has been consumed without restarting the rpd process. This issue affects Junos OS based devices with either IPv4 or IPv6 LDP enabled via the [protocols ldp] configuration (the native IPv6 support for LDP is available in Junos OS 16.1 and higher). The interface on which the packet arrives needs to have LDP enabled. • http://www.securityfocus.com/bid/97611 http://www.securitytracker.com/id/1038252 https://kb.juniper.net/JSA10777 • CWE-772: Missing Release of Resource after Effective Lifetime •
CVE-2017-2313
https://notcve.org/view.php?id=CVE-2017-2313
Juniper Networks devices running affected Junos OS versions may be impacted by the receipt of a crafted BGP UPDATE which can lead to an rpd (routing process daemon) crash and restart. Repeated crashes of the rpd daemon can result in an extended denial of service condition. The affected Junos OS versions are: 15.1 prior to 15.1F2-S15, 15.1F5-S7, 15.1F6-S5, 15.1F7, 15.1R4-S7, 15.1R5-S2, 15.1R6; 15.1X49 prior to 15.1X49-D78, 15.1X49-D80; 15.1X53 prior to 15.1X53-D230, 15.1X53-D63, 15.1X53-D70; 16.1 prior to 16.1R3-S3, 16.1R4; 16.2 prior to 16.2R1-S3, 16.2R2; Releases prior to Junos OS 15.1 are unaffected by this vulnerability. 17.1R1, 17.2R1, and all subsequent releases have a resolution for this vulnerability. Dispositivos de Juniper Networks que ejecutan las versiones afectadas Junos OS pueden verse afectados por el recibo de una BGP UPDATE manipulada que puede conducir a un fallo y un reinicio del rpd (enrutamiento del daemon del proceso). Los repetidos bloqueos del daemon rpd pueden resultar en una condición extendida de denegación de servicio. • http://www.securityfocus.com/bid/97606 http://www.securitytracker.com/id/1038257 https://kb.juniper.net/JSA10778 • CWE-20: Improper Input Validation •
