Details

A missing break statement in DSI OpenSession processing in Netatalk 1.5.0 through 4.4.2 causes a DSIOPTATTNQUANT switch case to fall through into DSIOPTSERVQUANT, resulting in unintended session option handling that may allow a remote attacker to cause a minor service disruption via crafted DSI session options.
