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
7 products (26 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 2
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
13 products (2,329 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 8
The c_rehash script does not properly sanitise shell metacharacters to prevent command injection. 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 3.0.3 (Affected 3.0.0,3.0.1,3.0.2). Fixed in OpenSSL 1.1.1o (Affected 1.1.1-1.1.1n). Fixed in OpenSSL 1.0.2ze (Affected 1.0.2-1.0.2zd).
