+OpenSSL Security Advisory [22nd May 2025]
+=========================================
+
+The x509 application adds trusted use instead of rejected use (CVE-2025-4575)
+=============================================================================
+
+Severity: Low
+
+Issue summary: Use of -addreject option with the openssl x509 application adds
+a trusted use instead of a rejected use for a certificate.
+
+Impact summary: If a user intends to make a trusted certificate rejected for
+a particular use it will be instead marked as trusted for that use.
+
+A copy & paste error during minor refactoring of the code introduced this
+issue in the OpenSSL 3.5 version. If, for example, a trusted CA certificate
+should be trusted only for the purpose of authenticating TLS servers but not
+for CMS signature verification and the CMS signature verification is intended
+to be marked as rejected with the -addreject option, the resulting CA
+certificate will be trusted for CMS signature verification purpose instead.
+
+Only users which use the trusted certificate format who use the openssl x509
+command line application to add rejected uses are affected by this issue.
+The issues affecting only the command line application are considered to
+be Low severity.
+
+The FIPS modules in 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by this
+issue.
+
+OpenSSL 3.4, 3.3, 3.2, 3.1, 3.0, 1.1.1 and 1.0.2 are also not affected by this
+issue.
+
+OpenSSL 3.5 is vulnerable to this issue.
+
+OpenSSL 3.5 users should upgrade to OpenSSL 3.5.1 once it is released.
+
+Due to the low severity of this issue we are not issuing new releases of
+OpenSSL at this time. The fix will be included in the next release of 3.5
+branch, once it becomes available. The fix is also available in commit
+e96d2244 (for 3.5) in the OpenSSL git repository.
+
+This issue was reported on 2nd May 2025 by Alexandr Sosedkin (Red Hat).
+The fix was developed by Tomáš Mráz.
