[openssl-dev] [openssl.org #4466] Memory leak in PKCS12_newpass function

[Ramūnas Jurgilas via RT]

I did write function which changes PKCS12 passphrase. I noticed that PKCS12_newpass function leaks memory. Memory leak disappears when commenting out line where is PKCS12_newpass func.

Below I posted this code which I am using.
I am using OpneSSL 1.0.2g version.

Could you please give me information what I am doing wrong? Or it is known issue?

Bets regards,
Ramunas

- (NSData*)changePKCS12:(NSData*)p12Data
          oldPassphrase:(NSString*)oldPassphrase
          newPassphrase:(NSString*)newPassphrase {
    OpenSSL_add_all_algorithms();
    BIO *bp = NULL;
    PKCS12 *p12 = NULL;
    int status = 0;
    do {
        bp = BIO_new_mem_buf((void *)[p12Data bytes], (int)[p12Data length]);

        p12 = d2i_PKCS12_bio(bp, NULL);

// MEMORY LEAK in PKCS12_newpass
        status = PKCS12_newpass(p12, (char *)[oldPassphrase UTF8String], (char *)[newPassphrase UTF8String]);
    } while (false);

    if (p12) {
        PKCS12_free(p12);
        p12 = NULL;
    }
    if (bp) {
        BIO_free_all(bp);
        bp = NULL;
    }
    EVP_cleanup();
    return NULL;
}
