CVE-2017-10618 – Junos: RPD core due to BGP UPDATE with malformed optional transitive attributes
https://notcve.org/view.php?id=CVE-2017-10618
When the 'bgp-error-tolerance' feature â€" designed to help mitigate remote session resets from malformed path attributes â€" is enabled, a BGP UPDATE containing a specifically crafted set of transitive attributes can cause the RPD routing process to crash and restart. Devices with BGP enabled that do not have 'bgp-error-tolerance' configured are not vulnerable to this issue. Affected releases are Juniper Networks Junos OS 13.3 prior to 13.3R10-S2; 14.1 prior to 14.1R8-S4, 14.1R9; 14.1X50 prior to 14.1X50-D185; 14.1X53 prior to 14.1X53-D45, 14.1X53-D50; 14.2 prior to 14.2R7-S7, 14.2R8; 15.1 prior to 15.1F5-S8, 15.1F6-S7, 15.1R5-S6, 15.1R6-S2, 15.1R7; 15.1X49 prior to 15.1X49-D100; 15.1X53 prior to 15.1X53-D64, 15.1X53-D70; 16.1 prior to 16.1R3-S4, 16.1R4-S3, 16.1R5; 16.2 prior to 16.2R1-S5, 16.2R2; 17.1 prior to 17.1R1-S3, 17.1R2; 17.2 prior to 17.2R1-S2, 17.2R2; 17.2X75 prior to 17.2X75-D50. No other Juniper Networks products or platforms are affected by this issue.

CVE-2017-10611 – Junos: EX Series PFE and MX MPC7E/8E/9E PFE crash when fetching interface stats with 'extended-statistics' enabled
https://notcve.org/view.php?id=CVE-2017-10611
If extended statistics are enabled via 'set chassis extended-statistics', when executing any operation that fetches interface statistics, including but not limited to SNMP GET requests, the pfem process or the FPC may crash and restart. Repeated crashes of PFE processing can result in an extended denial of service condition. This issue only affects the following platforms: (1) EX2200, EX3300, XRE200 (2) MX Series routers with MPC7E/8E/9E PFEs installed, and only if 'extended-statistics' are enabled under the [edit chassis] configuration. Affected releases are Juniper Networks Junos OS 14.1 prior to 14.1R8-S5, 14.1R9 on MX Series; 14.1X53 prior to 14.1X53-D46, 14.1X53-D50 on EX2200, EX3300, XRE200; 14.2 prior to 14.2R7-S9, 14.2R8 on MX Series; 15.1 prior to 15.1F5-S8, 15.1F6-S8, 15.1R5-S3, 15.1R6 on MX Series; 16.1 prior to 16.1R4-S5, 16.1R5, 16.1R6 on MX Series; 16.1X65 prior to 16.1X65-D45 on EX2200, EX3300, XRE200; 16.2 prior to 16.2R2-S1, 16.2R3 on MX Series; 17.1 prior to 17.1R2-S2, 17.1R3 on MX Series; 17.2 prior to 17.2R1-S3, 17.2R2 on MX Series; 17.2X75 prior to 17.2X75-D50 on MX Series; 17.3 prior to 17.3R1-S1, 17.3R2 on MX Series.

CVE-2017-2345 – Junos: snmpd denial of service upon receipt of crafted SNMP packet
https://notcve.org/view.php?id=CVE-2017-2345
On Junos OS devices with SNMP enabled, a network based attacker with unfiltered access to the RE can cause the Junos OS snmpd daemon to crash and restart by sending a crafted SNMP packet. Repeated crashes of the snmpd daemon can result in a partial denial of service condition. Additionally, it may be possible to craft a malicious SNMP packet in a way that can result in remote code execution. SNMP is disabled in Junos OS by default. Junos OS devices with SNMP disabled are not affected by this issue. • http://www.securityfocus.com/bid/99567 http://www.securitytracker.com/id/1038903 https://kb.juniper.net/JSA10793 • CWE-20: Improper Input Validation •
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 •
