What the vendors declare (VEX)
Official vendor statements in CSAF/VEX format: whether their product is affected, already fixed, or ruled out — and why. These are the vendor's assertions, not Vexday's judgment.

Affected
8 products (27 components)
Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9 · Red Hat Virtualization 4 · and others 3
workaround: As mentioned in the upstream security advisory, use of the c_rehash script is considered obsolete and should be replaced by the OpenSSL rehash command-line tool.
Fixed
19 products (144 components)
Red Hat Enterprise Linux BaseOS (v. 8) · Red Hat Enterprise Linux BaseOS (v. 9) · Red Hat Enterprise Linux AppStream (v. 9) · Red Hat JBoss Core Services on RHEL 8 · Satellite Client 6 for RHEL 7 · and others 14
Not affected
12 products (2,328 components) — because the vulnerable code is not present in the product
Red Hat Satellite 6.14 for RHEL 8 · Red Hat JBoss Core Services on RHEL 8 · Red Hat Satellite 6.13 for RHEL 8 · Red Hat JBoss Core Services on RHEL 7 Server · Satellite Client 6 for RHEL 8 · and others 7
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. Fixed in OpenSSL 3.0.4 (Affected 3.0.0,3.0.1,3.0.2,3.0.3). Fixed in OpenSSL 1.1.1p (Affected 1.1.1-1.1.1o). Fixed in OpenSSL 1.0.2zf (Affected 1.0.2-1.0.2ze).
