NVD description
Espruino 2v29 (commit bffc6d0) contains a NULL pointer dereference vulnerability in jslGetRawString() in src/jslex.c. Crafted raw/binary string input can cause the lexer to pass a NULL iterator target to jsvLockAgain(). In RELEASE/NO_ASSERT builds, the missing assertion guard allows a write through the NULL pointer, resulting in memory corruption and application termination or denial of service.
