This upgrade fixes CVE-2018-1000180 [1]:
Bouncy Castle BC 1.54 - 1.59, BC-FJA 1.0.0, BC-FJA 1.0.1 and earlier
have a flaw in the Low-level interface to RSA key pair generator,
specifically RSA Key Pairs generated in low-level API with added
certainty may have less M-R tests than expected. This appears to be
fixed in versions BC 1.60 beta 4 and later, BC-FJA 1.0.2 and later.
and CVE-2018-1000613 [2]:
Bouncy Castle Java Cryptography APIs version prior to version 1.60
contains a CWE-470: Use of Externally-Controlled Input to Select
Classes or Code ('Unsafe Reflection') vulnerability in XMSS/XMSS^MT
private key deserialization that can result in Deserializing an
XMSS/XMSS^MT private key can result in the execution of unexpected
code. This attack appear to be exploitable via a handcrafted private
key can include references to unexpected classes which will be picked
up from the class path for the executing application. This
vulnerability appears to have been fixed in 1.60 and later.
