Name of the Vulnerable Software and Affected Versions Moddable SDK OS180329 version 9.0.0

Description The issue is a heap-based buffer overflow in the fxBeginHost function in xsAPI.c when called from fxRunDefine in xsRun.c. This can be triggered by crafted JavaScript code sent to xst.

Recommendations For Moddable SDK OS180329 version 9.0.0, consider restricting access to the fxBeginHost function in xsAPI.c until a patch is available. As a temporary workaround, avoid using the fxRunDefine function in xsRun.c that calls fxBeginHost to minimize the risk of exploitation.
