+# Use-after-free following `BIO_new_NDEF`
+
+The public API function `BIO_new_NDEF` is a helper function used for streaming
+ASN.1 data via a `BIO`. It is primarily used internally to OpenSSL to support the
+SMIME, CMS and PKCS7 streaming capabilities, but may also be called directly by
+end user applications.
+
+The function receives a `BIO` from the caller, prepends a new `BIO_f_asn1` filter
+`BIO` onto the front of it to form a `BIO` chain, and then returns the new head of
+the `BIO` chain to the caller. Under certain conditions, for example if a CMS
+recipient public key is invalid, the new filter `BIO` is freed and the function
+returns a `NULL` result indicating a failure. However, in this case, the `BIO` chain
+is not properly cleaned up and the `BIO` passed by the caller still retains
+internal pointers to the previously freed filter `BIO`. If the caller then goes on
+to call `BIO_pop()` on the `BIO` then a use-after-free will occur. This will most
+likely result in a crash.
+
+This scenario occurs directly in the internal function `B64_write_ASN1()` which
+may cause `BIO_new_NDEF()` to be called and will subsequently call `BIO_pop()` on
+the `BIO`. This internal function is in turn called by the public API functions
+`PEM_write_bio_ASN1_stream`, `PEM_write_bio_CMS_stream`, `PEM_write_bio_PKCS7_stream`,
+`SMIME_write_ASN1`, `SMIME_write_CMS` and `SMIME_write_PKCS7`.
+
+Other public API functions that may be impacted by this include
+`i2d_ASN1_bio_stream`, `BIO_new_CMS`, `BIO_new_PKCS7`, `i2d_CMS_bio_stream` and
+`i2d_PKCS7_bio_stream`.
