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.
