An Insecure Default Initialization of Resource vulnerability in Juniper Networks Junos OS Evolved allows an unauthenticated, network based attacker to read certain confidential information. In the default configuration it is possible to read confidential information about locally configured (administrative) users of the affected system. This issue affects Juniper Networks Junos OS Evolved: All versions prior to 20.4R3-S7-EVO on pending commit???; 21.1-EVO versions prior to 21.1R3-S4-EVO on awaiting build; 21.4-EVO versions prior to 21.4R3-S1-EVO; 22.2-EVO versions prior to 22.2R3-EVO; 21.2-EVO versions prior to 21.2R3-S5-EVO on pending commit???; 21.3-EVO version 21.3R1-EVO and later versions; 22.1-EVO version 22.1R1-EVO and later versions; 22.2-EVO versions prior to 22.2R2-S1-EVO.

A Use of Uninitialized Resource vulnerability in the Border Gateway Protocol (BGP) software of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network-based attacker to send specific genuine BGP packets to a device configured with BGP to cause a Denial of Service (DoS) by crashing the Routing Protocol Daemon (rpd). This issue is triggered when the packets attempt to initiate a BGP connection before a BGP session is successfully established. Continued receipt of these specific BGP packets will cause a sustained Denial of Service condition. This issue is triggerable in both iBGP and eBGP deployments. This issue affects: Juniper Networks Junos OS 21.1 version 21.1R1 and later versions prior to 21.1R3-S5; 21.2 version 21.2R1 and later versions prior to 21.2R3-S2; 21.3 version 21.3R1 and later versions prior to 21.3R3-S2; 21.4 versions prior to 21.4R3; 22.1 versions prior to 22.1R3; 22.2 versions prior to 22.2R2.

A Missing Release of Memory after Effective Lifetime vulnerability in the routing process daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an attacker to send a malformed BGP Path attribute update which allocates memory used to log the bad path attribute. This memory is not properly freed in all circumstances, leading to a Denial of Service (DoS). Consumed memory can be freed by manually restarting Routing Protocol Daemon (rpd). Memory utilization could be monitored by:  user@host> show system memory or show system monitor memory status This issue affects: Junos OS:  * All versions before 21.2R3-S8,  * from 21.4 before 21.4R3-S8, * from 22.2 before 22.2R3-S4,  * from 22.3 before 22.3R3-S3,  * from 22.4 before 22.4R3-S3, * from 23.2 before 23.2R2-S1,  * from 23.4 before 23.4R1-S2, 23.4R2.

A Use After Free vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an authenticated, network-based attacker to cause a Denial of Service (DoS).On all Junos OS and Junos Evolved platforms, if a routing-instance deactivation is triggered, and at the same time a specific SNMP request is received, a segmentation fault occurs which causes rpd to crash and restart. This issue affects:    Junos OS: * All versions before 21.2R3-S8,  * 21.4 versions before 21.4R3-S5, * 22.2 versions before 22.2R3-S3, * 22.3 versions before 22.3R3-S2, * 22.4 versions before 22.4R3, * 23.2 versions before 23.2R2.   Junos OS Evolved: * All versions before 21.2R3-S8-EVO, * 21.4-EVO versions before 21.4R3-S5-EVO, * 22.2-EVO versions before 22.2R3-S3-EVO,  * 22.3-EVO versions before 22.3R3-S2-EVO, * 22.4-EVO versions before 22.4R3-EVO, * 23.2-EVO versions before 23.2R2-EVO.

An Improper Neutralization of Special Elements vulnerability in Juniper Networks Junos OS Evolved commands allows a local, authenticated attacker with low privileges to escalate their privileges to 'root' leading to a full compromise of the system. The Junos OS Evolved CLI doesn't properly handle command options in some cases, allowing users which execute specific CLI commands with a crafted set of parameters to escalate their privileges to root on shell level. This issue affects Junos OS Evolved: All versions before 20.4R3-S7-EVO, 21.2-EVO versions before 21.2R3-S8-EVO, 21.4-EVO versions before 21.4R3-S7-EVO,  22.2-EVO versions before 22.2R3-EVO, 22.3-EVO versions before 22.3R2-EVO, 22.4-EVO versions before 22.4R2-EVO.

An Improper Check for Unusual or Exceptional Conditions vulnerability in packet processing of Juniper Networks Junos OS Evolved may allow a network-based unauthenticated attacker to crash the device (vmcore) by sending a specific TCP packet over an established TCP session with MD5 authentication enabled, destined to an accessible port on the device, resulting in a Denial of Service (DoS).  The receipt of this packet must occur within a specific timing window outside the attacker's control (i.e., race condition). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue only affects dual RE systems with Nonstop Active Routing (NSR) enabled. Exploitation can only occur over TCP sessions with MD5 authentication enabled (e.g., BGP with MD5 authentication). This issue affects Junos OS Evolved:  * All versions before 21.2R3-S8-EVO, * from 21.4-EVO before 21.4R3-S6-EVO, * from 22.1-EVO before 22.1R3-S4-EVO, * fr…

An Unchecked Return Value vulnerability in the Routing Protocol Daemon (rpd) on Juniper Networks Junos OS and Juniper Networks Junos OS Evolved allows a logically adjacent, unauthenticated attacker sending a specific PIM packet to cause rpd to crash and restart, resulting in a Denial of Service (DoS), when PIM is configured with Multicast-only Fast Reroute (MoFRR). Continued receipt and processing of this packet may create a sustained Denial of Service (DoS) condition. This issue is observed on Junos and Junos Evolved platforms where PIM is configured along with MoFRR. MoFRR tries to select the active path, but due to an internal timing issue, rpd is unable to select the forwarding next-hop towards the source, resulting in an rpd crash. This issue affects: Junos OS: * All versions before 20.4R3-S10, * from 21.2 before 21.2R3-S7, * from 21.4 before 21.4R3-S6, * from 22.1 before 22.1R3-S5, * from 22.2 before 22.2R3-S3, * from 22.3 before 22.3R3, * from 2…
