Issue Overview:

A flaw was found in OpenSSL. The issue in CVE-2022-1292 did not find other places in the c_rehash script where it possibly passed the file names of certificates being hashed to a command executed through the shell. Some operating systems distribute this script in a manner where it is automatically executed. On these operating systems, this flaw allows an attacker to execute arbitrary commands with the privileges of the script. (CVE-2022-2068)
