An Out-of-Bounds Read vulnerability in
the routing protocol daemon (rpd) of
Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network-based attacker sending a specifically malformed BGP packet to cause rpd to crash and restart, resulting in a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition.
This issue only affects systems configured in
either of two ways:
* systems with BGP traceoptions enabled
* systems with BGP traffic engineering
configured
This issue can affect iBGP and eBGP with
any address family
configured. The specific attribute involved is non-transitive, and will not propagate across a network.
This issue affects:
Junos OS:
* All versions before 21.4R3-S8,
* 22.2 before 22.2R3-S5,
* 22.3 before 22.3R3-S4,

An Improper Handling of Exceptional Conditions vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network-based attacker sending a specific BGP packet to cause rpd to crash and restart, resulting in a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition.
This issue only affects systems with BGP traceoptions enabled and
requires a BGP session to be already established. Systems without BGP traceoptions enabled are not affected by this issue.
This issue affects iBGP and eBGP, and both IPv4 and IPv6 are affected by this vulnerability.

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,

A Missing Release of Memory after Effective Lifetime vulnerability in the rtlogd process of Juniper Networks Junos OS on MX Series with SPC3 allows an unauthenticated, adjacent attacker to trigger internal events cause ( which can be done by repeated port flaps) to cause a slow memory leak, ultimately leading to a Denial of Service (DoS).
Memory can only be recovered by manually restarting rtlogd process.
The memory usage can be monitored using the below command.
user@host> show system processes extensive | match rtlog

* 23.2 versions before 23.2R2,
* 23.4 versions before 23.4R1-S1, 23.4R2,

An Improper Check for Unusual or Exceptional Conditions vulnerability in the flow daemon (flowd) of Juniper Networks Junos OS on
SRX4600 and SRX5000 Series
allows an attacker to send TCP packets with
SYN/FIN or SYN/RST
flags, bypassing the expected blocking of these packets.
A TCP packet with SYN/FIN or SYN/RST should be dropped in flowd. However, when no-syn-check and Express Path are enabled, these TCP packets are unexpectedly transferred to the downstream network.
This issue affects Junos OS on SRX4600 and SRX5000 Series:
* All versions before 21.2R3-S8,
* from 21.4 before 21.4R3-S7,
* from 22.1 before 22.1R3-S6,

An Improper Neutralization of Data within XPath Expressions ('XPath Injection') vulnerability in J-Web shipped with Juniper Networks Junos OS allows an unauthenticated, network-based attacker to execute remote commands on the target device.
While an administrator is logged into a J-Web session or has previously logged in and subsequently logged out of their J-Web session, the attacker can arbitrarily execute commands on the target device with the other user's credentials. In the worst case, the attacker will have full control over the device.
This issue affects Junos OS:
* All versions before 21.2R3-S8,
* from 21.4 before 21.4R3-S7,
* from 22.2 before 22.2R3-S4,

* from 23.4 before 23.4R1-S1, 23.4R2.
A Stack-Based Buffer Overflow vulnerability in Juniper Networks Junos OS and Juniper Networks Junos OS Evolved may allow a local, low-privileged attacker with access to the CLI the ability to load a malicious certificate file, leading to a limited Denial of Service (DoS) or privileged code execution.
By exploiting the 'set security certificates' command with a crafted certificate file, a malicious attacker with access to the CLI could cause a crash of the command management daemon (mgd), limited to the local user's command interpreter, or potentially trigger a stack-based buffer overflow.
This issue affects:
Junos OS:
* All versions before 21.4R3-S7,
* from 22.1 before 22.1R3-S6,

An Improper Check for Unusual or Exceptional Conditions vulnerability in the Layer 2 Address Learning Daemon (l2ald) on Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause Denial of Service (DoS).
In an EVPN/VXLAN scenario, when a high amount specific Layer 2 packets are processed by the device, it can cause the Routing Protocol Daemon (rpd) to utilize all CPU resources which causes the device to hang. A manual restart of the rpd is required to restore services.
This issue affects both IPv4 and IPv6 implementations.
