The c_rehash script allows command injection (CVE-2022-2068)
============================================================
Severity: Moderate
In addition to the c_rehash shell command injection identified in
CVE-2022-1292, further circumstances where the c_rehash script does not
properly sanitise 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.
