Description

This security bulletin contains information about 1 vulnerability.


1) Encoding Error (CVE-ID: N/A)

CWE-ID: CWE-172 - Encoding Error

CVSSv4: 6 [CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


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

The vulnerability exists due to an encoding error in ValueReader.readShortstr and ValueWriter.writeShortstr when processing an AMQP message with malformed UTF-8 shortstr properties. A remote user can send a specially crafted AMQP message to cause a denial of service.

The issue affects RPC consumers that echo received shortstr property values, and the unacknowledged message is requeued for subsequent consumers.
