This function is used when decoding certificates or keys. The OPENSSL_LH_flush() function, which empties a hash table, contains a bug that breaks reuse of the memory occuppied by the removed hash table entries. Use of the c_rehash script is considered obsolete and should be replaced by the OpenSSL rehash command line tool. On such operating systems, an attacker could execute arbitrary commands with the privileges of the script. This script is distributed by some operating systems in a manner where it is automatically executed. 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.

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. Since OpenSSL does not support OCB based cipher suites for TLS and DTLS, they are both unaffected. In the special case of "in place" encryption, sixteen bytes of the plaintext would be revealed. This could reveal sixteen bytes of data that was preexisting in the memory that wasn't written.
