yasm 1.3.0.55.g101bc was discovered to contain a stack overflow via the function parse_expr5 at /nasm/nasm-parse.c. Note: This has been disputed by third parties who argue this is a bug and not a security issue because yasm is a standalone program not designed to run untrusted code.
The product writes data past the end, or before the beginning, of the intended buffer.
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
