+Subject: [PATCH] [PATCH] pk7_doit.c: Check return of BIO_set_md() calls
+
+These calls invoke EVP_DigestInit() which can fail for digests
+with implicit fetches. Subsequent EVP_DigestUpdate() from BIO_write()
+or EVP_DigestFinal() from BIO_read() will segfault on NULL
+dereference. This can be triggered by an attacker providing
+PKCS7 data digested with MD4 for example if the legacy provider
+is not loaded.
+
+If BIO_set_md() fails the md BIO cannot be used.
