| yassl-inputbufferoperator-bo (39431) |  High Risk |
Description:
yaSSL is vulnerable to a buffer overflow, caused by improper bounds checking by the yaSSL input_buffer& operator function. By sending an overly long Hello packet, a remote attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the application to crash.
