Name of the Vulnerable Software and Affected Versions Espruino version 2V00

Description The issue is related to a stack-based buffer over-read in the jsfNameFromString function, located in the jsflash.c file. This can lead to a denial of service or potentially other unspecified impacts when a crafted js file is used.

Recommendations For Espruino version 2V00, consider avoiding the use of crafted js files until a patch is available. As a temporary workaround, restricting access to the jsfNameFromString function may help minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
