1) Out-of-bounds write (CVE-ID: CVE-2023-24823)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error during IPHC send. A remote attacker can trigger an out-of-bounds write and execute arbitrary code on the target system.


2) NULL pointer dereference (CVE-ID: CVE-2023-24818)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error during fragment forwarding. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.


3) Out-of-bounds write (CVE-ID: CVE-2023-24819)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error during IPHC receive. A remote attacker can trigger an out-of-bounds write and execute arbitrary code on the target system.


4) Integer underflow (CVE-ID: CVE-2023-24820)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to integer underflow during IPHC receive. A remote attacker can send a specially crafted request to the affected application, trigger integer underflow and cause a denial of service condition on the target system.


5) Integer underflow (CVE-ID: CVE-2023-24821)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to integer underflow during defragmentation. A remote attacker can send a specially crafted request to the affected application, trigger integer underflow and cause a denial of service condition on the target system.


6) NULL pointer dereference (CVE-ID: CVE-2023-24822)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error during IPHC encoding. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
