Hi,
in the ELF format, the PT_INTERP segment contains the path of the
interpreter which must be loaded. For this segment, the kernel looks
at these values in the program header:
p_offset: offset of the path string
p_filesz: size of the path string, including the \0
The path string must be a val
13 matches
