Public bug reported:
Hi developers:
We made a large scale security static analysis on several open source
projects, and found some mistakes in dnsval-2.0. In the @libval/valdane.c:743:
int val_dane_check(val_context_t *ctx,SSL *con,struct val_danestatus
*danestatus,int *do_pathval)
{
[...]
switch (dane_cur->usage) {
[...]
case DANE_USE_SVC_CONSTRAINT: /*1*/
cert = SSL_get_peer_certificate(con);
cert_datalen = i2d_X509(cert, NULL);
[...]
}
In this function,you do cert verify . But the API
SSL_get_peer_certificate and SSL_get_verify_result do not in the same
case.There may exist some problem?
