2013-10-18curl_sasl: initialize NSS before using cryptoKamil Dudka
2013-08-25sasl: added basic SASL XOAUTH2 supportKyle L. Huff
Added the ability to generated a base64 encoded XOAUTH2 token containing: "user=<username>^Aauth=Bearer <bearer token>^A^A" as per RFC6749 "OAuth 2.0 Authorization Framework".
2013-08-20sasl: allow arbitrarily long username and passwordJonathan Nieder
Use appropriately sized buffers on the heap instead of fixed-size buffers on the stack, to allow for longer usernames and passwords. Callers never pass anything longer than MAX_CURL_USER_LENGTH (resp. MAX_CURL_PASSWORD_LENGTH), so no functional change inteded yet.
2013-06-25formpost: better random boundariesDaniel Stenberg
When doing multi-part formposts, libcurl used a pseudo-random value that was seeded with time(). This turns out to be bad for users who formpost data that is provided with users who then can guess how the boundary string will look like and then they can forge a different formpost part and trick the receiver. My advice to such implementors is (still even after this change) to not rely on the boundary strings being cryptographically strong. Fix your code and logic to not depend on them that much! I moved the Curl_rand() function into the sslgen.c source file now to be able to take advantage of the SSL library's random function if it provides one. If not, try to use the RANDOM_FILE for seeding and as a last resort keep the old logic, just modified to also add microseconds which makes it harder to properly guess the exact seed. The formboundary() function in formdata.c is now using 64 bit entropy for the boundary and therefore the string of dashes was reduced by 4 letters and there are 16 hex digits following it. The total length is thus still the same. Bug: http://curl.haxx.se/bug/view.cgi?id=1251 Reported-by: "Floris"
2013-03-21sasl: Corrected a few violations of the curl coding standardsSteve Holme
Corrected some incorrectly positioned pointer variable declarations to be "char *" rather than "char* ".
2013-02-12sasl: Fixed null pointer reference when decoding empty digest challengeSteve Holme
Fixed a null pointer reference when an empty challenge is passed to the Curl_sasl_create_digest_md5_message() function. Bug: http://sourceforge.net/p/curl/bugs/1193/ Reported by: Saran Neti
2013-02-06Curl_sasl_create_digest_md5_message: fix buffer overflowEldar Zaitov
When negotiating SASL DIGEST-MD5 authentication, the function Curl_sasl_create_digest_md5_message() uses the data provided from the server without doing the proper length checks and that data is then appended to a local fixed-size buffer on the stack. This vulnerability can be exploited by someone who is in control of a server that a libcurl based program is accessing with POP3, SMTP or IMAP. For applications that accept user provided URLs, it is also thinkable that a malicious user would feed an application with a URL to a server hosting code targetting this flaw. Bug: http://curl.haxx.se/docs/adv_20130206.html
2013-01-22curl_sasl.c: Corrected references to RFCSteve Holme
The most recent version of the RFC is RFC4422 and not RFC2222 as previously documented.
2013-01-09build: fix circular header inclusion with other packagesYang Tse
This commit renames lib/setup.h to lib/curl_setup.h and renames lib/setup_once.h to lib/curl_setup_once.h. Removes the need and usage of a header inclusion guard foreign to libcurl. [1] Removes the need and presence of an alarming notice we carried in old setup_once.h [2] ---------------------------------------- 1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H, this single inclusion guard is enough to ensure that inclusion of lib/setup_once.h done from lib/setup.h is only done once. Additionally lib/setup.h has always used __SETUP_ONCE_H macro to protect inclusion of setup_once.h even after commit ec691ca3, this was to avoid a circular header inclusion triggered when building a c-ares enabled version with c-ares sources available which also has a setup_once.h header. Commit ec691ca3 exposes the real nature of __SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard foreign to libcurl belonging to c-ares's setup_once.h The renaming this commit does, fixes the circular header inclusion, and as such removes the need and usage of a header inclusion guard foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl. 2 - Due to the circular interdependency of old lib/setup_once.h and the c-ares setup_once.h header, old file lib/setup_once.h has carried back from 2006 up to now days an alarming and prominent notice about the need of keeping libcurl's and c-ares's setup_once.h in sync. Given that this commit fixes the circular interdependency, the need and presence of mentioned notice is removed. All mentioned interdependencies come back from now old days when the c-ares project lived inside a curl subdirectory. This commit removes last traces of such fact.

2012-06-15SSPI related code: Unicode support for WinCEMark Salisbury
SSPI related code now compiles with ANSI and WCHAR versions of security methods (WinCE requires WCHAR versions of methods). Pulled UTF8 to WCHAR conversion methods out of idn_win32.c into their own file. curl_sasl.c - include curl_memory.h to use correct memory functions. getenv.c and telnet.c - WinCE compatibility fix With some committer adjustments
