I've tried with the following snippet:
= START SNIPPET
#include
#include
#include
#include
int
main(int argc, char *argv[])
{
EVP_MD_CTX *mdctx = NULL;
unsigned char sign_value[1024];
int sign_len, i;
EVP_PKEY *pkey = NULL;
RSA *rpkey = NULL;
FILE *rpkey_file;
mdctx = EVP_MD_CTX_create();
rpkey_file = fopen("./rsa.key", "r");
if (!rpkey_file) {
return 3;
}
PEM_read_RSAPrivateKey(rpkey_file, &rpkey, NULL, NULL);
pkey = EVP_PKEY_new();
EVP_PKEY_set1_RSA(pkey, rpkey);
EVP_SignInit_ex(mdctx, EVP_sha1(), NULL);
EVP_SignUpdate(mdctx, "abracadabra0", strlen("abracadabra0"));
EVP_SignUpdate(mdctx, "abracadabra1", strlen("abracadabra1"));
EVP_SignUpdate(mdctx, "abracadabra2", strlen("abracadabra2"));
EVP_SignUpdate(mdctx, "abracadabra3", strlen("abracadabra3"));
EVP_SignUpdate(mdctx, "abracadabra4", strlen("abracadabra4"));
EVP_SignFinal(mdctx, sign_value, (unsigned int *)&sign_len, pkey);
sign_value[sign_len] = '\0';
EVP_MD_CTX_destroy(mdctx);
printf("Signature is: ");
for(i = 0; i < sign_len; i++) {
printf("%02x", sign_value[i]);
}
printf("\n");
fclose(rpkey_file);
return 0;
}
= END SNIPPET
It does the same thing as the code in the phar extension producing a signature.
Running that with valgrind gives a bunch of messages about openssl. After
reading the openssl wiki http://www.openssl.org/support/faq.html#PROG13 I think
the actual issue here is that no cleanup is performed on openssl, but that's a
more global issue.
Thus, there is no clean run with or without the patch using valgrind. But the
patch fixes the test run on windows, so i think it's worth to apply it.

Note that the previous trace was produced on CentOS using openssl 1.0.0 where
under windows the bug shows up with openssl 0.9.8x .

Expected result:
test Pass
Actual result:

There are several popups with the following messages when runnign on a debug
build:

Run-Time Check Failure #2 - Stack around the variable 'md_ctx' was corrupted
After the test has run, it's marked as passed though.
