Description Sam Fowler 2018-02-09 05:12:13 UTC
A Denial of Service vulnerability was found in Apache Qpid Broker-J 7.0.0 in functionality for authentication of connections for AMQP protocols 0-8, 0-9, 0-91 and 0-10 when PLAIN or XOAUTH2 SASL mechanism is used. The vulnerability allows an unauthenticated attacker to crash the broker instance. AMQP 1.0 and HTTP connections are not affected.

The following Authentication Providers support PLAIN SAML and are affected:
- Plain
- PlainPasswordFile
- SimpleLDAP
- Base64MD5PasswordFile
- MD5

The following Authentication Providers support XOAUTH2 SAML and are affected:
- OAuth2

The current implementation of SASL mechanisms PLAIN and XOAUTH2 require from client to provide an initial response. PLAIN and XOAUTH2 sasl mechanism implementations should send challenge (empty bytes) if initial response is not provided.

Comment 1 Sam Fowler 2018-02-09 05:16:26 UTC
Created qpid-java tracking bugs for this issue:

Affects: fedora-all [bug 1543718]

Comment 2 Kurt Seifried 2018-02-09 16:33:43 UTC
Satellite 6 uses qpid-cpp, not qpid-java, so removing from affected.

Comment 3 Jason Shepherd 2018-02-12 04:41:28 UTC
The affected Java classes are not present in MRG-2, or MRG-M-3. They were added in version 7 of qpid-broker-j which is the upstream project.

Comment 4 Jason Shepherd 2018-02-12 04:43:30 UTC
JBoss A-MQ, and Fuse only contain the qpid client libraries, not the broker implementation.
