The TS_RESP_verify_response() function is used for verifying the response from a TSA. You can set the provided TS_VERIFY_CTX with different flags depending on what aspects of the response you wish to verify. A seg fault will occur if you supply the TS_VFY_SIGNER or TS_VFY_TSA_NAME flags without also specifying TS_VFY_SIGNATURE. Reviewed-by:Rich Salz <rsalz@openssl.org>

Operations in the DSA signing algorithm should run in constant time in order to avoid side channel attacks. A flaw in the OpenSSL DSA implementation means that a non-constant time codepath is followed for certain operations. This has been demonstrated through a cache-timing attack to be sufficient for an attacker to recover the private DSA key. CVE-2016-2178 Reviewed-by:

According to the x509 man page in the section discussing -certopt it says that the ca_default option is the same as that used by the ca utility and (amongst other things) has the effect of suppressing printing of the signature - but in fact it doesn't. This error seems to have been present since the documentation was written back in 2001. It never had this effect. The default config file sets the certopt value to ca_default. The ca utility takes that and THEN adds additional options to suppress printing of the signature. So the ca utility DOES suppress printing of the signature - but it is not as a result of using the ca_default option. GitHub Issue #247 Reviewed-by:

If the string to print is exactly 2048 character long (excluding the NULL terminator) then BIO_printf will chop off the last byte. This is because it has filled its static buffer but hasn't yet allocated a dynamic buffer. In cases where we don't have a dynamic buffer we need to truncate but that is not the case for BIO_printf(). We need to check whether we are able to have a dynamic buffer buffer deciding to truncate. Reviewed-by: -

A common idiom in the codebase is: if (p + len > limit) { return; /* Too long */ } Where "p" points to some malloc'd data of SIZE bytes and limit == p + SIZE "len" here could be from some externally supplied data (e.g. from a TLS message). The rules of C pointer arithmetic are such that "p + len" is only well defined where len <= SIZE. Therefore the above idiom is actually undefined behaviour. For example this could cause problems if some malloc implementation provides an address for "p" such that "p + len" actually overflows for values of len that are too big and therefore p + len < limit!

Set ctx->error = X509_V_ERR_OUT_OF_MEM when verificaiton cannot continue due to malloc failure. Similarly for issuer lookup failures and caller errors (bad parameters or invalid state). Also, when X509_verify_cert() returns <= 0 make sure that the verification status does not remain X509_V_OK, as a last resort set it it to X509_V_ERR_UNSPECIFIED, just in case some code path returns an error without setting an appropriate value of ctx->error.
