FreeBSD -- copy_file_range insufficient capability rights check

Problem Description: The syscall checked only for the CAPREAD and CAPWRITE capabilities on the input and output file descriptors, respectively. Using an offset is logically equivalent to seeking, and the syscall must additionally require the CAPSEEK capability. Impact: A sandboxed process with on...
