Espruino 2v20 (commit fcc9ba4) was discovered to contain a Stack Overflow via the jspeFactorFunctionCall at src/jsparse.c.

Buffer Overflow vulnerability found in Espruino 2v05.41 allows an attacker to cause a denial of service via the function jsvGarbageCollectMarkUsed in file src/jsvar.c.

An issue found in Espruino Espruino 6ea4c0a allows an attacker to execute arbitrrary code via oldFunc parameter of the jswrap_object.c:jswrap_function_replacewith endpoint.

Espruino 2v11 release was discovered to contain a stack buffer overflow via src/jsvar.c in jsvGetNextSibling.

Espruino 2v11.251 was discovered to contain a stack buffer overflow via src/jsvar.c in jsvNewFromString.

Espruino 2v10.246 was discovered to contain a stack buffer overflow via src/jsutils.c in vcbprintf.

Espruino 2v11.251 was discovered to contain a stack buffer overflow via src/jsvar.c in jsvNewFromString.

Espruino 2v11.251 was discovered to contain a SEGV vulnerability via src/jsinteractive.c in jsiGetDeviceFromClass.

Buffer overflow vulnerability in function jsvGetStringChars in Espruino before RELEASE_2V09, allows remote attackers to execute arbitrary code.

Espruino before 1.99 allows attackers to cause a denial of service (application crash) and a potential Information Disclosure with user crafted input files via a Buffer Overflow or Out-of-bounds Read during syntax parsing of certain for loops in jsparse.c.

Espruino before 1.99 allows attackers to cause a denial of service (application crash) with a user crafted input file via a Buffer Overflow during syntax parsing because of a missing check for stack exhaustion with many '{' characters in jsparse.c.

Espruino before 1.99 allows attackers to cause a denial of service (application crash) with a user crafted input file via a Buffer Overflow during syntax parsing because a check for '\0' is made for the wrong array element in jsvar.c.

Espruino before 1.99 allows attackers to cause a denial of service (application crash) and a potential Escalation of Privileges with a user crafted input file via a Buffer Overflow during syntax parsing, because strncat is misused.

Espruino before 1.99 allows attackers to cause a denial of service (application crash) with a user crafted input file via a Buffer Overflow during syntax parsing of "VOID" tokens in jsparse.c.

Espruino before 1.99 allows attackers to cause a denial of service (application crash) and potential Information Disclosure with a user crafted input file via a Buffer Overflow during syntax parsing because strncpy is misused in jslex.c.

Espruino before 1.98 allows attackers to cause a denial of service (application crash) with a user crafted input file via an Out-of-bounds Read during syntax parsing in which certain height validation is missing in libs/graphics/jswrap_graphics.c.

Espruino before 1.98 allows attackers to cause a denial of service (application crash) with a user crafted input file via a NULL pointer dereference during syntax parsing. This was addressed by adding validation for a debug trace print statement in jsvar.c.

Espruino before 1.99 allows attackers to cause a denial of service (application crash) with a user crafted input file via an integer overflow during syntax parsing. This was addressed by fixing stack size detection on Linux in jsutils.c.
