5de2580563 Make ssl_set_ecdh_curves() a compile-time option 2014-02-06 10:28:38 +01:00
Gergely Budai
987bfb510b Added the possibility to define the allowed curves for ECDHE handshake. It also defines the preference of the curves. 2014-02-06 10:28:38 +01:00

956c9e063d Reduced the input / output overhead with 200+ bytes and covered corner
case

The actual input / output buffer overhead is only 301 instead of 512.
This requires a proper check on the padding_idx to prevent out of bounds
reads.

Previously a remote party could potentially trigger an access error and
thus stop the application when sending a malicious packet having
MAX_CONTENT_LEN of data, 32 bytes of MAC and a decrypted padlen of .
This would result in reading from in_ctr + 13 + 32 + MAX_CONTENT_LEN - 1 - 1
for 256 bytes (including fake padding check). Or 13 + 32 bytes over the
buffer length.

We now reset padding_idx to 0, if it's clear that it will never be a
valid padding (padlen > msg_len || msg_len + padlen + 256 > buffer_len)

28d81a009c Fix pkcs11.c to conform to PolarSSL 1.3 API.
This restores previous functionality, and thus still allows only RSA to be
used through PKCS#11.
