Description

This security bulletin contains information about 1 vulnerability.


1) Input validation error (CVE-ID: N/A)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


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

The vulnerability exists due to improper input validation in CommandAssembler when processing malformed AMQP content header and body frames from a connected broker peer. A remote user can send a specially crafted frame sequence to cause a denial of service.

Exploitation requires a broker peer that the client has connected to and an open non-zero channel that can receive a content-bearing server-to-client method.
