When reading in the original file name from gzip header, we read in PATH_MAX + 1 bytes from the file. In r281500, strrchr() is used to strip possible path portion of the file name to mitigate a possible attack. Unfortunately, strrchr() expects a buffer that is NUL-terminated, and since we are processing potentially untrusted data, we can not assert that be always true. Solve this by reading in one less byte (now PATH_MAX) and explicitly terminate the buffer after the read size with NUL. |
