+# Timing Oracle in RSA Decryption
+
+A timing based side channel exists in the OpenSSL RSA Decryption implementation
+which could be sufficient to recover a plaintext across a network in a
+Bleichenbacher style attack. To achieve a successful decryption an attacker
+would have to be able to send a very large number of trial messages for
+decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5,
+RSA-OEAP and RSASVE.
+
+For example, in a TLS connection, RSA is commonly used by a client to send an
+encrypted pre-master secret to the server. An attacker that had observed a
+genuine connection between a client and a server could use this flaw to send
+trial messages to the server and record the time taken to process them. After a
+sufficiently large number of messages the attacker could recover the pre-master
+secret used for the original connection and thus be able to decrypt the
+application data sent over that connection.
