Description
The vulnerability allows a remote user to cause heap overflow on the target system.

The weakness is caused by insufficient input validation. By sending a great deal of input data attackers are able to cause overflow of the EVP_EncodeUpdate() function used for binary data encoding.

Successful exploitation of the vulnerability may result in heap overflow on the vulnerable system.

Mitigation
Update 1.0.1 to 1.0.1t.
Update 1.0.2 to 1.0.2h.
