[openssl-dev] [openssl.org #4560] BUG: openssl-1.0.2h, evp_enc.c, fips, use of uninitialized variable

[Loic Etienne via RT]

crypto/evp/evp_enc.c, EVP_CipherInit_ex, line 172
    const EVP_CIPHER *fcipher;
    if (cipher)
        fcipher = evp_get_fips_cipher(cipher);
    if (fcipher)
        cipher = fcipher;
    return FIPS_cipherinit(ctx, cipher, key, iv, enc);

problem:
    if (!cipher), fcipher is not initialized but used

possible fix:
    const EVP_CIPHER *fcipher = evp_get_fips_cipher(cipher);
    return FIPS_cipherinit(ctx, fcipher ? fcipher : cipher, key, iv, enc);
