vendor/openssl: import 3.0.18vendor/openssl/3.0.18

Per the upstream release notes, this is a security release. However,
all of the needed fixes/mitigations have been deployed to all relevant
14.x branches making the update in this change less critical. This just
aids with future release backporting.

+### Changes between 3.0.17 and 3.0.18 [30 Sep 2025]
+
+ * Fix Out-of-bounds read & write in RFC 3211 KEK Unwrap
+
+   Issue summary: An application trying to decrypt CMS messages encrypted using
+   password based encryption can trigger an out-of-bounds read and write.
+
+   Impact summary: This out-of-bounds read may trigger a crash which leads to
+   Denial of Service for an application. The out-of-bounds write can cause
+   a memory corruption which can have various consequences including
+   a Denial of Service or Execution of attacker-supplied code.
+
+   The issue was reported by Stanislav Fort (Aisle Research).
+
+   ([CVE-2025-9230])
+
+   *Viktor Dukhovni*
+
+ * Fix Out-of-bounds read in HTTP client no_proxy handling
+
+   Issue summary: An application using the OpenSSL HTTP client API functions
+   may trigger an out-of-bounds read if the "no_proxy" environment variable is
+   set and the host portion of the authority component of the HTTP URL is an
+   IPv6 address.
+
+   Impact summary: An out-of-bounds read can trigger a crash which leads to
+   Denial of Service for an application.
+
+   The issue was reported by Stanislav Fort (Aisle Research).
+
+   ([CVE-2025-9232])
+
+   *Stanislav Fort*
+
+ * Avoided a potential race condition introduced in 3.0.17, where
+   `OSSL_STORE_CTX` kept open during lookup while potentially being used
+   by multiple threads simultaneously, that could lead to potential crashes
+   when multiple concurrent TLS connections are served.
+
+   *Matt Caswell*
+
+ * Secure memory allocation calls are no longer used for HMAC keys.
+
+   *Dr Paul Dale*
+
+ * `openssl req` no longer generates certificates with an empty extension list
+   when SKID/AKID are set to `none` during generation.
+
+   *David Benjamin*
+
+ * The man page date is now derived from the release date provided
+   in `VERSION.dat` and not the current date for the released builds.
+
+   *Enji Cooper*
+
+ * Hardened the provider implementation of the RSA public key "encrypt"
+   operation to add a missing check that the caller-indicated output buffer
+   size is at least as large as the byte count of the RSA modulus.  The issue
+   was reported by Arash Ale Ebrahim from SYSPWN.
+
+   This operation is typically invoked via `EVP_PKEY_encrypt(3)`.  Callers that
+   in fact provide a sufficiently large buffer, but fail to correctly indicate
+   its size may now encounter unexpected errors.  In applications that attempt
+   RSA public encryption into a buffer that is too small, an out-of-bounds
+   write is now avoided and an error is reported instead.
+
+   *Viktor Dukhovni*
