This is a similar, but different vulnerability than the issue reported as CVE-2024-39549.
A double-free 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 double free of memory is causing an rpd crash, leading to a Denial of Service (DoS).
This issue affects:
Junos OS: * from 22.4 before 22.4R3-S4.
Junos OS Evolved: * from 22.4 before 22.4R3-S4-EVO.

This issue requires a BGP session to be established.
This issue can propagate and multiply through multiple ASes until reaching vulnerable devices.
This issue affects iBGP and eBGP.
This issue affects IPv4 and IPv6.
An indicator of compromise may be the presence of malformed update messages in a neighboring AS which is unaffected by this issue:
For example, by issuing the command on the neighboring device:
show log messages
Reviewing for similar messages from devices within proximity to each other may indicate this malformed packet is propagating:
rpd[<pid>]: Received malformed update from <IP address> (External AS <AS#>)
and
rpd[<pid>]: Malformed Attribute

An Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the command-line interface (CLI) of Juniper Networks Junos OS on SRX Series devices allows a local, low-privileged user with access to the Junos CLI to view the contents of sensitive files on the file system.
Through the execution of either 'show services advanced-anti-malware' or 'show services security-intelligence' command, a user with limited permissions (e.g., a low privilege login class user) can access protected files that should not be accessible to the user. These files may contain sensitive information that can be used to cause further impact to the system.
This issue affects Junos OS SRX Series:
* All versions before 21.4R3-S8,
* from 22.2 before 22.2R3-S5,
* from 22.3 before 22.3R3-S3,

An Improper Handling of Exceptional Conditions vulnerability in the command-line processing of Juniper Networks Junos OS on SRX1500, SRX4100, and SRX4200 devices allows a local, low-privileged authenticated attacker executing the 'show chassis environment pem' command to cause the chassis daemon (chassisd) to crash and restart, resulting in a temporary Denial of Service (DoS). However, repeated execution of this command will eventually cause the chassisd process to fail to restart, impacting packet processing on the system.
