      char ascii_header[112];
...
      sprintf (ascii_header,
              
"%6s%08lx%08lx%08lx%08lx%08lx%08lx%08lx%08lx%08lx%08lx%08lx%08lx%08lx",
               magic_string,
               file_hdr->c_ino, file_hdr->c_mode, file_hdr->c_uid,
               file_hdr->c_gid, file_hdr->c_nlink, file_hdr->c_mtime,
             file_hdr->c_filesize, file_hdr->c_dev_maj, file_hdr->c_dev_min,
           file_hdr->c_rdev_maj, file_hdr->c_rdev_min, file_hdr->c_namesize,
               file_hdr->c_chksum);

...

cpio assumes the filesize is at most 8 digits in size... and that's not right.
If it's more, this buffer will indeed overflow....

this probably wants to use asprintf() or so

Please note that this is only a security issue on 64 bit platforms.


This issue should also affect RHEL2.1 and RHEL3
