H A Dccm.c2373e1b994ffd66a0cb1872a17a0d3d825eeda4e Thu Sep 01 06:46:35 UTC 2022 Jens Wiklander <jens.wiklander@linaro.org> core: add overflow checks in crypto_aes_ccm_init()

aad_len and payload_len are of the type size_t which has a greater range
than int which is used for the corresponding arguments when passed to
ccm_init(). So to guard against wrapped or truncated values check that
the variables can be in a int first before calling ccm_init().
