CWE-416
AllowedUse After Free
Abstraction: Variant · Status: Stable
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
9821 vulnerabilities reference this CWE, most recent first.

Title
Junos OS and Junos OS Evolved: When telemetry collectors are frequently subscribing and unsubscribing to sensors chassisd or rpd will crash
Summary
A Use After Free vulnerability in the chassis daemon (chassisd) of Juniper Networks Junos OS and Junos OS Evolved allows a network-based attacker authenticated with low privileges to cause a Denial-of-Service (DoS).
When telemetry collectors are frequently subscribing and unsubscribing to sensors continuously over a long period of time, telemetry-capable processes like chassisd, rpd or mib2d will crash and restart, which - depending on the process - can cause a complete outage until the system has recovered.
This issue affects:
Junos OS:
* all versions before 22.4R3-S8,
* 23.2 versions before 23.2R2-S5,
* 23.4 versions before 23.4R2;
Junos OS Evolved:
* all versions before 22.4R3-S8-EVO,
* 23.2 versions before 23.2R2-S5-EVO,
* 23.4 versions before 23.4R2-EVO.

Title
Junos OS and Junos OS Evolved: Use after free vulnerability In 802.1X authentication daemon can cause crash of the dot1xd process
Summary
A Use After Free vulnerability was identified in the 802.1X authentication daemon (dot1xd) of Juniper Networks Junos OS and Junos OS Evolved that could allow an authenticated, network-adjacent attacker flapping a port to crash the dot1xd process, leading to a Denial of Service (DoS), or potentially execute arbitrary code within the context of the process running as root.
The issue is specific to the processing of a change in authorization (CoA) when a port bounce occurs. A pointer is freed but was then referenced later in the same code path. Successful exploitation is outside the attacker's direct control due to the specific timing of the two events required to execute the vulnerable code path.
This issue affects systems with 802.1X authentication port-based network access control (PNAC) enabled.
This issue affects:
Junos OS:
* from 23.2R2-S1 before 23.2R2-S5,
* from 23.4R2 before 23.4R2-S6,
* from 24.2 before 24.2R2-S3,
* from 24.4 before 24.4R2-S1,
* from 25.2 before 25.2R1-S2, 25.2R2;
Junos OS Evolved:
* from 23.2R2-S1 before 23.2R2-S5-EVO,
* from 23.4R2 before 23.4R2-S6-EVO,
* from 24.2 before 24.2R2-S3-EVO,
* from 24.4 before 24.4R2-S1-EVO,
* from 25.2 before 25.2R1-S2-EVO, 25.2R2-EVO.

"value": "A Use After Free vulnerability was identified in the 802.1X authentication daemon (dot1xd) of\u00a0Juniper Networks Junos OS and Junos OS Evolved that could allow an authenticated, network-adjacent attacker flapping a port to crash the dot1xd process, leading to a Denial of Service (DoS), or potentially execute arbitrary code within the context of the process running as root.\n\nThe issue is specific to the processing of a change in authorization (CoA) when a port bounce occurs. A pointer is freed but was then referenced later in the same code path. Successful exploitation is outside the attacker\u0027s direct control due to the specific timing of the two events required to execute the vulnerable code path.\n\nThis issue affects systems with 802.1X authentication port-based network access control (PNAC) enabled.\nThis issue affects:\n\nJunos OS:\u00a0\n\n\n\n * from 23.2R2-S1 before 23.2R2-S5,\u00a0\n * from 23.4R2 before 23.4R2-S6,\u00a0\n * from 24.2 before 24.2R2-S3,\u00a0\n * from 24.4 before 24.4R2-S1,\u00a0\n * from 25.2 before 25.2R1-S2, 25.2R2;\u00a0\n\n\n\n\nJunos OS Evolved:\u00a0\n\n\n\n * from 23.2R2-S1 before 23.2R2-S5-EVO,\u00a0\n * from 23.4R2 before 23.4R2-S6-EVO,\u00a0\n * from 24.2 before 24.2R2-S3-EVO,\u00a0\n * from 24.4 before 24.4R2-S1-EVO,\u00a0\n * from 25.2 before 25.2R1-S2-EVO, 25.2R2-EVO."
