1) Resource exhaustion (CVE-ID: CVE-2022-41723)

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

The vulnerability exists due to application does not properly control consumption of internal resources in the HPACK decoder. A remote attacker can send a specially crafted HTTP/2 stream to the application, cause resource exhaustion and perform a denial of service (DoS) attack.


2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-34969)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

If a local privileged user (e.g. root) is using the org.freedesktop.DBus.Monitoring interface to monitor message bus traffic, another unprivileged user with the ability to connect to the same dbus-daemon can force the service to send an unreplyable message and perform a denial of service (DoS) attack.
