Name of the Vulnerable Software and Affected Versions Netatalk versions 1.5.0 through 4.4.2

Description A missing break statement in DSI OpenSession processing causes a DSIOPT ATTNQUANT switch case to fall through into DSIOPT SERVQUANT. This leads to unintended session option handling, which may allow a remote attacker to cause a minor service disruption by using crafted DSI session options.
