| Doc Text: |
The fsck.vfat utility terminated due to buffer overflow. This occurred when checking a device with the corrupted VFAT file system if there were any chains of orphaned clusters. The name of the newly created file that contained these clusters was printed directly into the name field, which led to an out of boundary write. The name is now printed into the buffer and individual parts are then correctly copied into the appropriate field.
