If output_cmd_background is given a valid mode as the first argument, then there is no file given and an error should be returned. join_args should not be called with an argc of zero since it sets the last character to the null terminator. With an argc of zero, the length is zero causing a heap buffer overflow when setting the byte before the start of argv to '\0'. This probably will not ever generate a segfault, but may cause data corruption to whatever is directly before it in memory. To make other such cases easier to detect, this also adds a sway_assert in join_args when argc is zero. |
