A timing-based side-channel flaw exists in the perl-Crypt-OpenSSL-RSA
package, which could be sufficient to recover plaintext across a network in
a Bleichenbacher-style attack. To achieve successful decryption, an
attacker would have to be able to send a large number of trial messages.
The vulnerability affects the legacy PKCS#1v1.5 RSA encryption padding
mode.
