A vulnerability was found in SoX, where a heap-buffer-overflow occurs in function lsx_read_w_buf() in formats_i.c file. The vulnerability is exploitable with a crafted file, that could cause an application to crash.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
The product writes data past the end, or before the beginning, of the intended buffer.
