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.
The Juniper Enhanced jdhcpd daemon may experience high CPU utilization, or crash and restart upon receipt of an invalid IPv6 UDP packet. Both high CPU utilization and repeated crashes of the jdhcpd daemon can result in a denial of service as DHCP service is interrupted. No other Juniper Networks products or platforms are affected by this issue. Affected releases are Juniper Networks Junos OS 14.1X53 prior to 14.1X53-D12, 14.1X53-D38, 14.1X53-D40 on QFX, EX, QFabric System; 15.1 prior to 15.1F2-S18, 15.1R4 on all products and platforms; 15.1X49 prior to 15.1X49-D80 on SRX; 15.1X53 prior to 15.1X53-D51, 15.1X53-D60 on NFX, QFX, EX.
Receipt of a malformed BGP OPEN message may cause the routing protocol daemon (rpd) process to crash and restart. By continuously sending specially crafted BGP OPEN messages, an attacker can repeatedly crash the rpd process causing prolonged denial of service. No other Juniper Networks products or platforms are affected by this issue. Affected releases are Juniper Networks Junos OS 12.3 prior to 12.3R12-S4, 12.3R13, 12.3R3-S4; 12.3X48 prior to 12.3X48-D50; 13.3 prior to 13.3R4-S11, 13.3R10; 14.1 prior to 14.1R8-S3, 14.1R9; 14.1X53 prior to 14.1X53-D40; 14.1X55 prior to 14.1X55-D35; 14.2 prior to 14.2R4-S7, 14.2R6-S4, 14.2R7; 15.1 prior to 15.1F2-S11, 15.1F4-S1-J1, 15.1F5-S3, 15.1F6, 15.1R4; 15.1X49 prior to 15.1X49-D100; 15.1X53 prior to 15.1X53-D33, 15.1X53-D50.
A buffer overflow vulnerability in Junos OS CLI may allow a local authenticated user with read only privileges and access to Junos CLI, to execute code with root privileges. Affected releases are Juniper Networks Junos OS: 14.1X53 versions prior to 14.1X53-D46 on EX2200/VC, EX3200, EX3300/VC, EX4200, EX4300, EX4550/VC, EX4600, EX6200, EX8200/VC (XRE), QFX3500, QFX3600, QFX5100; 14.1X53 versions prior to 14.1X53-D130 on QFabric System; 14.2 versions prior to 14.2R4-S9, 14.2R6; 15.1 versions prior to 15.1F5, 15.1R3; 15.1X49 versions prior to 15.1X49-D40 on SRX Series; 15.1X53 versions prior to 15.1X53-D47 on NFX150, NFX250; 15.1X53 versions prior to 15.1X53-D65 on QFX10000 Series; 15.1X53 versions prior to 15.1X53-D233 on QFX5110, QFX5200.
An XML injection vulnerability in Junos OS CLI can allow a locally authenticated user to elevate privileges and run arbitrary commands as the root user. This issue was found during internal product security testing. Affected releases are Juniper Networks Junos OS 15.1X53 prior to 15.1X53-D47, 15.1 prior to 15.1R3. Junos versions prior to 15.1 are not affected. No other Juniper Networks products or platforms are affected by this issue.
On Juniper Networks products or platforms running Junos OS 11.4 prior to 11.4R13-S3, 12.1X46 prior to 12.1X46-D60, 12.3 prior to 12.3R12-S2 or 12.3R13, 12.3X48 prior to 12.3X48-D40, 13.2X51 prior to 13.2X51-D40, 13.3 prior to 13.3R10, 14.1 prior to 14.1R8, 14.1X53 prior to 14.1X53-D12 or 14.1X53-D35, 14.1X55 prior to 14.1X55-D35, 14.2 prior to 14.2R7, 15.1 prior to 15.1F6 or 15.1R3, 15.1X49 prior to 15.1X49-D60, 15.1X53 prior to 15.1X53-D30 and DHCPv6 enabled, when a crafted DHCPv6 packet is received from a subscriber, jdhcpd daemon crashes and restarts. Repeated crashes of the jdhcpd process may constitute an extended denial of service condition for subscribers attempting to obtain IPv6 addresses.
On Juniper Networks products or platforms running Junos OS 12.1X46 prior to 12.1X46-D50, 12.1X47 prior to 12.1X47-D40, 12.3 prior to 12.3R13, 12.3X48 prior to 12.3X48-D30, 13.2X51 prior to 13.2X51-D40, 13.3 prior to 13.3R10, 14.1 prior to 14.1R8, 14.1X53 prior to 14.1X53-D35, 14.1X55 prior to 14.1X55-D35, 14.2 prior to 14.2R5, 15.1 prior to 15.1F6 or 15.1R3, 15.1X49 prior to 15.1X49-D30 or 15.1X49-D40, 15.1X53 prior to 15.1X53-D35, and where RIP is enabled, certain RIP advertisements received by the router may cause the RPD daemon to crash resulting in a denial of service condition.
Juniper Networks QFX3500, QFX3600, QFX5100, QFX5200, EX4300 and EX4600 devices running Junos OS 14.1X53 prior to 14.1X53-D40, 15.1X53 prior to 15.1X53-D40, 15.1 prior to 15.1R2, do not pad Ethernet packets with zeros, and thus some packets can contain fragments of system memory or data from previous packets. This issue is also known as 'Etherleak'
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. The affected Junos versions are: 13.3 prior to 13.3R10; 14.1 prior to 14.1R8; 14.2 prior to 14.2R7-S6 or 14.2R8; 15.1 prior to 15.1F2-S14, 15.1F6-S4, 15.1F7, 15.1R4-S7, 15.1R5; 15.1X49 before 15.1X49-D70; 15.1X53 before 15.1X53-D230, 15.1X53-D63, 15.1X53-D70; 16.1 before 16.1R2. 16.2R1 and all subsequent releases have a resolution for this vulnerability.
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.
