EUVDB-ID: #VU32483

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2014-3636

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

The vulnerability allows a local non-authenticated attacker to perform service disruption.

D-Bus 1.3.0 through 1.6.x before 1.6.24 and 1.8.x before 1.8.8 allows local users to (1) cause a denial of service (prevention of new connections and connection drop) by queuing the maximum number of file descriptors or (2) cause a denial of service (disconnect) via multiple messages that combine to have more than the allowed number of file descriptors for a single sendmsg call.

Mitigation

Install update from vendor's website.
