Author: Henning Westerholt <[email protected]> Committer: Henning Westerholt <[email protected]> Date: 2020-11-09T12:53:36Z crypto: properly initialize key and iv to 0, add comment regarding the size of IV - properly initialize key and iv to 0, otherwise invalid data might be printed - the initialization vector for AES will be always AES blocksize, e.g. 128 bits (cherry picked from commit e9624bc4823cfba0bd9536a70b9eeadecb2a537e) --- Modified: src/modules/crypto/crypto_aes.c --- Diff: https://github.com/kamailio/kamailio/commit/4b5f5636143037ff6620b88e03e57c05a91eabc4.diff Patch: https://github.com/kamailio/kamailio/commit/4b5f5636143037ff6620b88e03e57c05a91eabc4.patch --- diff --git a/src/modules/crypto/crypto_aes.c b/src/modules/crypto/crypto_aes.c index 8b80d62a29..f9aacf5410 100644 --- a/src/modules/crypto/crypto_aes.c +++ b/src/modules/crypto/crypto_aes.c @@ -76,7 +76,9 @@ int crypto_aes_init(unsigned char *key_data, int key_data_len, { int i, nrounds = 5; int x; - unsigned char key[32], iv[32]; + unsigned char key[32], iv[32]; /* IV is only 16 bytes, but makes it easier */ + memset(key, 0, sizeof(key)); + memset(iv, 0, sizeof(iv)); /* * Gen key & IV for AES 256 CBC mode.
