LOW

Netatalk 1.5.0-4.4.2 and >=4.5.0 - Denial of Service via DSI OpenSession Processing

Title source: llm
STIX 2.1

Description

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