Cesanta MJS v2.20.0 was discovered to contain a SEGV vulnerability via gc_sweep at src/mjs_gc.c. This vulnerability can lead to a Denial of Service (DoS).
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
