  shell metacharacters to prevent command injection were found by code review.

  When the CVE-2022-1292 was fixed it was not discovered that there are other places in the script
  where the file names of certificates being hashed were possibly passed to a command executed
  through the shell.

  This script is distributed by some operating systems in a manner where it is automatically
  executed. On such operating systems, an attacker could execute arbitrary commands with the
  privileges of the script.

  Use of the c_rehash script is considered obsolete and should be replaced by the OpenSSL rehash
  command line tool.");
