FKIE_CVE-2024-1930

Vulnerability from fkie_nvd - Published: 2024-05-08 02:15 - Updated: 2026-06-17 07:05
Severity
6.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H
Summary
No Limit on Number of Open Sessions / Bad Session Close Behaviour in dnf5daemon-server before 5.1.17 allows a malicious user to impact Availability via No Limit on Number of Open Sessions. There is no limit on how many sessions D-Bus clients may create using the `open_session()` D-Bus method. For each session a thread is created in dnf5daemon-server. This spends a couple of hundred megabytes of memory in the process. Further connections will become impossible, likely because no more threads can be spawned by the D-Bus service.
