Description:
 Crypto++ (aka cryptopp and libcrypto++) 5.6.4 contained a bug in its ASN.1
 BER decoding routine. The library will allocate a memory block based on the
 length field of the ASN.1 object. If there is not enough content octets in
 the ASN.1 object, then the function will fail and the memory block will be
 zeroed even if its unused. There is a noticeable delay during the wipe for
 a large allocation.
