DTLS is not sending alert in case of BAD CCS

[Raja ashok <raja.ashok@xxxxxxxxxx>]

Hi All,

 

Looks like there is a typo mistake in dtls1_read_bytes, because of this alert is not send for bad CCS.

 

In dtls1_read_bytes, incase of bad change cipher spec we are setting alert code (SSL_AD_ILLEGAL_PARAMETER) to variable “i” and doing “goto err”. I feel we are trying to send alert in this case, so we need to set the alert in “al” and do “goto f_err”.

 

In case of TLS we are sending alert.

 

Note : I am referring 1.0.2.k version of OpenSSL

 

Regards,

Ashok
