Juniper JUNOS 13.3 R6

An Improper Validation of Syntactic Correctness of Input vulnerability in the Juniper DHCP daemon (jdhcpd) of Juniper Networks Junos OS allows an adjacent unauthenticated attacker sending a malformed DHCP packet to cause a crash of jdhcpd and thereby a Denial of Service (DoS). If option-82 is configured in a DHCP snooping / -security scenario, jdhcpd crashes if a specific malformed DHCP request packet is received. The DHCP functionality is impacted while jdhcpd restarts, and continued exploitation of the vulnerability will lead to the unavailability of the DHCP service and thereby a sustained DoS. This issue affects Juniper Networks Junos OS 13.2 version 13.2R1 and later versions prior to 15.1R7-S11; 18.3 versions prior to 18.3R3-S6; 18.4 versions prior to 18.4R2-S9, 18.4R3-S10; 19.1 versions prior to 19.1R2-S3, 19.1R3-S7; 19.2 versions prior to 19.2R1-S8, 19.2R3-S4; 19.3 versions prior to 19.3R2-S7, 19.3R3-S4; 19.4 versions prior to 19.4R3-S6; 20.1 versions prior to 20.1R3-S3; 20.2 versions prior to 20.2R3-S3; 20.3 versions prior to 20.3R3-S1; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R2-S1, 21.1R3; 21.2 versions prior to 21.2R1-S1, 21.2R2. This issue does not affect Juniper Networks Junos OS version 12.3R12 and prior versions.

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.

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. No other Juniper Networks products or platforms are affected by this issue. NOTE: This is a different issue than Cisco CVE-2017-6736, CVE-2017-6737, and CVE-2017-6738. 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-D44, 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, 15.1X49-D110; 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, 16.2R3; 17.1 prior to 17.1R1-S3, 17.1R2, 17.1R3; 17.2 prior to 17.2R1-S1, 17.2R2; 17.2X75 prior to 17.2X75-D30.

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. No other Juniper Networks products or platforms are affected by this issue.
