Potential Mitigations

Implementation

Ensure that an end condition will be reached under all logic conditions. The end condition may include checking against the depth of recursion and exiting with an error if the recursion goes too deep. The complexity of the end condition contributes to the effectiveness of this action.

Implementation

Increase the stack size.

CVE-2007-1285

Deeply nested arrays trigger stack exhaustion.

CVE-2007-3409

Self-referencing pointers create infinite loop and resultant stack exhaustion.

CVE-2016-10707

Javascript application accidentally changes input in a way that prevents a recursive call from detecting an exit condition.

CVE-2016-3627

An attempt to recover a corrupted XML file infinite recursion protection counter was not always incremented missing the exit condition.

CVE-2019-15118

USB-audio driver's descriptor code parsing allows unlimited recursion leading to stack exhaustion.
