Title
Missing break in DSI OpenSession
Summary
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.

Mitigation

Phase: Implementation

Description:

  • Omitting a break statement so that one may fall through is often indistinguishable from an error, and therefore should be avoided. If you need to use fall-through capabilities, make sure that you have clearly documented this within the switch statement, and ensure that you have examined all the logical possibilities.
Mitigation

Phase: Implementation

Description:

  • The functionality of omitting a break statement could be clarified with an if statement. This method is much safer.
