An integer overflow flaw, leading to a buffer overflow, was found in the way the EVP_EncodeUpdate() function of OpenSSL parsed very large amounts of input data. A remote attacker could use this flaw to crash an application using OpenSSL or, possibly, execute arbitrary code with the permissions of the user running that application.
