Bug: http://curl.haxx.se/mail/lib-2014-11/0035.html
Reported-by: Jan Ehrhardt
|
|
...as Curl_memdup() duplicates an area of fix size memory, that may be
binary, and not a null terminated string.
|
|
conversion from 'curl_off_t' to 'size_t', possible loss of data
|
|
To provide consistent behaviour between the various HTTP authentication
functions use CURLcode based error codes for Curl_input_digest()
especially as the calling code doesn't use the specific error code just
that it failed.
|
|
These were previously hard coded, and whilst defined in security.h,
they may or may not be present in old header files given that these
defines were never used in the original code.
Not only that, but there appears to be some ambiguity between the ANSI
and UNICODE NTLM definition name in security.h.
|
|
When duplicating a handle, the data to post was duplicated using
strdup() when it could be binary and contain zeroes and it was not even
zero terminated! This caused read out of bounds crashes/segfaults.
Since the lib/strdup.c file no longer is easily shared with the curl
tool with this change, it now uses its own version instead.

- Prior to this change no SSL minimum version was set by default at
runtime for PolarSSL. Therefore in most cases PolarSSL would probably
have defaulted to a minimum version of SSLv3 which is no longer secure.
|
|
The previous condition that checked if the socket was marked as readable
when also adding a writable one, was incorrect and didn't take the pause
bits properly into account.

autotools does not use features.h nor _BSD_SOURCE. As this macro
triggers warnings since glibc 2.20, remove it. It should not have
functional differences.

Typically the USE_WINDOWS_SSPI definition would not be used when the
CURL_DISABLE_CRYPTO_AUTH define is, however, it is still a valid build
configuration and, as such, the SASL Kerberos V5 (GSSAPI) authentication
data structures and functions would incorrectly be used when they
shouldn't be.
Introduced a new USE_KRB5 definition that takes into account the use of
CURL_DISABLE_CRYPTO_AUTH like USE_SPNEGO and USE_NTLM do.

More CURLcode fixes.
|

Basically since servers often then don't respond well to this and
instead send the full contents and then libcurl would instead error out
with the assumption that the server doesn't support resume. As the data
is then already transfered, this is now considered fine.
Test case 1434 added to verify this. Test case 1042 slightly modified.

More standardisation of CURLcode usage and coding style.

... and allow building with nghttp2 but completely without NPN and ALPN,
as nghttp2 can still be used for plain-text HTTP.

Return a more appropriate error, rather than CURLE_OUT_OF_MEMORY when
acquiring the credentials handle fails. This is then consistent with
the code prior to commit f7e24683c4 when log-in credentials were empty.
|
|
Fixed the ability to use the current log-in credentials with DIGEST-MD5.
I had previously disabled this functionality in commit 607883f13c as I
couldn't get this to work under Windows 8, however, from testing HTTP
Digest authentication through Windows SSPI and then further testing of
this code I have found it works in Windows 7.
Some further investigation is required to see what the differences are
between Windows 7 and 8, but for now enable this functionality as the
code will return an error when AcquireCredentialsHandle() fails.

Its last use has been removed by the previous commit.
|

This code was already deactivated by commit
ec783dc142129d3860e542b443caaa78a6172d56.

This check works also with to non-configure platforms.

HTTP 1.1 is clearly specified to only allow three digit response codes,
and libcurl used sscanf("%3d") for that purpose. This made libcurl
support smaller numbers but not larger. It does now, but we will not
make any specific promises nor document this further since it is going
outside of what HTTP is.

Don't call CompleteAuthToken() after InitializeSecurityContext() has
returned SEC_I_CONTINUE_NEEDED as this return code only indicates the
function should be called again after receiving a response back from
the server.
This only affected the Digest and NTLM authentication code.
|
|
For consistency with other areas of the NTLM code propagate all errors
from Curl_ntlm_core_mk_nt_hash() up the call stack rather than just
CURLE_OUT_OF_MEMORY.

If Apple ever drops SSLv3 support from the Security framework, we'll fail with an error if the user insists on using SSLv3.
