Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Use of insufficiently random values (CVE-ID: CVE-2024-47188)

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to use of insufficiently random values in http/byte-ranges byte-range tracking when processing byte-range data. A remote attacker can force large amounts of data into a single hash bucket to cause a denial of service.

The issue results in predictable hash table behavior and can lead to severe performance degradation.


2) Use of insufficiently random values (CVE-ID: CVE-2024-47187)

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to use of insufficiently random values in the thash hashtable implementation for datasets when loading dataset files or handling tracked traffic. A remote attacker can supply a crafted dataset or traffic patterns that trigger predictable hash table behavior to cause a denial of service.


3) Reachable assertion (CVE-ID: CVE-2024-47522)

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to reachable assertion in JA4 processing for TLS/QUIC traffic when handling invalid ALPN values. A remote attacker can send specially crafted TLS or QUIC traffic to cause a denial of service.

The issue is exposed when JA4 matching or logging is enabled.


4) Off-by-one (CVE-ID: CVE-2024-45796)

The vulnerability allows a remote attacker to bypass policy enforcement.

The vulnerability exists due to an off-by-one error in the defragmentation and fragment reassembly logic when processing crafted fragmented packets. A remote attacker can send specially crafted packets to bypass policy enforcement.

Valid traffic may fail reassembly when the issue is triggered.


5) Reachable assertion (CVE-ID: CVE-2024-45795)

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to reachable assertion in detect/datasets when parsing traffic with rules using datasets and the unimplemented "unset" option. A remote attacker can send traffic that matches a specially crafted rule to cause a denial of service.
