+From: Bob Beck <beck@openssl.org>
+Date: Fri, 5 Dec 2025 15:50:23 -0700
+Subject: [PATCH] Use non deprecated OpenSSL accessors for ASN1_STRING values.
+
+This changes your time conversion routine to use
+ASN1_STRING_get0_data() and ASN1_STRING_length() rather than
+directly using the values from the object.
+
+OpenSSL plans to make ASN1_STRING opaque soon:
+https://github.com/openssl/openssl/issues/29117
+
+The accessor in question is in OpenSSL 1.1 as well as
+BoringSSL and LibreSSL so should be widely available.
+
+As the returned value is const, and you are changing it
+to pass to strptime, I've made it make a copy to work with.
+
+Since I added another allocation I converted it to single
+return to ensure everything gets freed appropriately.
+
+Upstream-Status: Pending [https://github.com/Cisco-Talos/clamav/pull/1642]
