2014-10-08FormAdd: precaution against memdup() of NULL pointerDaniel Stenberg
Coverity CID 252518. This function is in general far too complicated for its own good and really should be broken down into several smaller funcitons instead - but I'm adding this protection here now since it seems there's a risk the code flow can end up here and dereference a NULL pointer.
2014-10-08do_sec_send: remove dead codeDaniel Stenberg
Coverity CID 1241951. The condition 'len >= 0' would always be true at that point and thus not necessary to check for.
2014-10-08krb5_encode: remove unused argumentDaniel Stenberg
Coverity CID 1241957. Removed the unused argument. As this struct and pointer now are used only for krb5, there's no need to keep unused function arguments around.
2014-10-07GnuTLS: Implement public key pinningmoparisthebest
2014-10-07SSL: implement public key pinningmoparisthebest
Option --pinnedpubkey takes a path to a public key in DER format and only connect if it matches (currently only implemented with OpenSSL). Provides CURLOPT_PINNEDPUBLICKEY for curl_easy_setopt(). Extract a public RSA key from a website like so: openssl s_client -connect google.com:443 2>&1 < /dev/null | \ sed -n '/-----BEGIN/,/-----END/p' | openssl x509 -noout -pubkey \ | openssl rsa -pubin -outform DER > google.com.der
2014-10-07multi_runsingle: fix possible memory leakDaniel Stenberg
Coverity CID 1202837. 'newurl' can in fact be allocated even when Curl_retry_request() returns failure so free it if need be.
2014-10-07ares::Curl_resolver_cancel: skip checking for NULL connDaniel Stenberg
Coverity CID 1243581. 'conn' will never be NULL here, and if it would be the subsequent statement would dereference it!
2014-10-06ssh_statemach_act: split out assignment from checkDaniel Stenberg
just a minor code style thing to make the code clearer
2014-10-04curl_schannel.c: Fixed possible memory or handle leakMarc Hoersken
First try to fix possible memory leaks, in this case: Only connssl->ctxt xor onnssl->cred being initialized.
2014-10-04choose_mech: fix return codeDaniel Stenberg
Coverity CID 1241950. The pointer is never NULL but it might point to NULL.
2014-10-04Curl_sec_read_msg: spell out that we ignore return codeDaniel Stenberg
Coverity CID 1241947. Since if sscanf() fails, the previously set value remains set.
2014-10-04nonblock: call with (void) to show we ignore the return codeDaniel Stenberg
Coverity pointed out several of these.
2014-10-03parse_proxy: remove dead code.Daniel Stenberg
Coverity CID 982331.
2014-10-03Curl_debug: document switch fallthroughsDaniel Stenberg
2014-10-03curl_multi_remove_handle: remove dead codeDaniel Stenberg
Coverify CID 1157776. Removed a superfluous if() that always evaluated true (and an else clause that never ran), and then re-indented the function accordingly.
2014-10-03Curl_pipeline_server_blacklisted: handle a NULL server nameDaniel Stenberg
Coverity CID 1215284. The server name is extracted with Curl_copy_header_value() and passed in to this function, and copy_header_value can actually can fail and return NULL.
2014-10-03ssh: comment "fallthrough" in switch statementDaniel Stenberg
2014-10-03ssh: improve key file searchJeremy Lin
For private keys, use the first match from: user-specified key file (if provided), ~/.ssh/id_rsa, ~/.ssh/id_dsa, ./id_rsa, ./id_dsa Note that the previous code only looked for id_dsa files. id_rsa is now generally preferred, as it supports larger key sizes. For public keys, use the user-specified key file, if provided. Otherwise, try to extract the public key from the private key file. This means that passing --pubkey is typically no longer required, and makes the key-handling behavior more like OpenSSH.
2014-10-02detect_proxy: fix possible single-byte memory leakDaniel Stenberg
Coverity CID 1202836. If the proxy environment variable returned an empty string, it would be leaked. While an empty string is not really a proxy, other logic in this function already allows a blank string to be returned so allow that here to avoid the leak.
2014-10-02multi_runsingle: fix memory leakDaniel Stenberg
Coverity CID 1202837. There's a potential risk that 'newurl' gets overwritten when it was already pointing to allocated memory.
2014-10-02pop3_perform_authentication: fix memory leakDaniel Stenberg
Coverity CID 1215287. There's a potential risk for a memory leak in here, and moving the free call to be unconditional seems like a cheap price to remove the risk.
2014-10-02imap_perform_authentication: fix memory leakDaniel Stenberg
Coverity CID 1215296. There's a potential risk for a memory leak in here, and moving the free call to be unconditional seems like a cheap price to remove the risk.
2014-10-02wait_or_timeout: return failure when Curl_poll() failsDaniel Stenberg
Coverity detected this. CID 1241954. When Curl_poll() returns a negative value 'mcode' was uninitialized. Pretty harmless since this is debug code only and would at worst cause an error to _not_ be returned...
2014-09-30smtp: Fixed intermittent "SSL3_WRITE_PENDING: bad write retry" errorBill Nagel
This patch fixes the "SSL3_WRITE_PENDING: bad write retry" error that sometimes occurs when sending an email over SMTPS with OpenSSL. OpenSSL appears to require the same pointer on a write that follows a retry (CURLE_AGAIN) as discussed here: http://stackoverflow.com/questions/2997218/why-am-i-getting-error1409f07fssl-routinesssl3-write-pending-bad-write-retr
2014-09-30file: reject paths using embedded %00Daniel Stenberg
Mostly because we use C strings and they end at a binary zero so we know we can't open a file name using an embedded binary zero. Reported-by: research@g0blin.co.uk
2014-09-25CURLOPT_COOKIELIST: Added "RELOAD" commandYousuke Kimoto
2014-09-23threaded-resolver: revert Curl_expire_latest() switchDaniel Stenberg
The switch to using Curl_expire_latest() in commit cacdc27f52b was a mistake and was against the advice even mentioned in that commit. The comparison in asyn-thread.c:Curl_resolver_is_resolved() makes Curl_expire() the suitable function to use. Bug: http://curl.haxx.se/bug/view.cgi?id=1426 Reported-By: graysky

2014-09-13http2: Fix busy loop when EOF is encounteredTatsuhiro Tsujikawa
Previously we did not handle EOF from underlying transport socket and wrongly just returned error code CURL_AGAIN from http2_recv, which caused busy loop since socket has been closed. This patch adds the code to handle EOF situation and tells the upper layer that we got EOF.

2014-09-12ntlm: Fixed HTTP proxy authentication when using Windows SSPIUlrich Telle
Removed ISC_REQ_* flags from calls to InitializeSecurityContext to fix bug in NTLM handshake for HTTP proxy authentication. NTLM handshake for HTTP proxy authentication failed with error SEC_E_INVALID_TOKEN from InitializeSecurityContext for certain proxy servers on generating the NTLM Type-3 message. The flag ISC_REQ_CONFIDENTIALITY seems to cause the problem according to the observations and suggestions made in a bug report for the QT project (https://bugreports.qt-project.org/browse/QTBUG-17322). Removing all the flags solved the problem. Bug: http://curl.haxx.se/mail/lib-2014-08/0273.html Reported-by: Ulrich Telle Assisted-by: Steve Holme, Daniel Stenberg

2014-09-10mk-ca-bundle.pl: first, try downloading HTTPS with curlDaniel Stenberg
As a sort of step forward, this script will now first try to get the data from the HTTPS URL using curl, and only if that fails it will switch back to the HTTP transfer using perl's native LWP functionality. To reduce the risk of this script being tricked. Using HTTPS to get a cert bundle introduces a chicken-and-egg problem so we can't really ever completely disable HTTP, but chances are that most users already have a ca cert bundle that trusts the mozilla.org site that this script downloads from. A future version of this script will probably switch to require a dedicated "insecure" command line option to allow downloading over HTTP (or unverified HTTPS).
2014-09-10cookies: reject incoming cookies set for TLDsDaniel Stenberg
Test 61 was modified to verify this. CVE-2014-3620 Reported-by: Tim Ruehsen URL: http://curl.haxx.se/docs/adv_20140910B.html
2014-09-10cookies: only use full host matches for hosts used as IP addressTim Ruehsen
By not detecting and rejecting domain names for partial literal IP addresses properly when parsing received HTTP cookies, libcurl can be fooled to both send cookies to wrong sites and to allow arbitrary sites to set cookies for others. CVE-2014-3613 Bug: http://curl.haxx.se/docs/adv_20140910A.html

2014-09-07Ensure progress.size_dl/progress.size_ul are always >= 0Brandon Casey
Historically the default "unknown" value for progress.size_dl and progress.size_ul has been zero, since these values are initialized implicitly by the calloc that allocates the curl handle that these variables are a part of. Users of curl that install progress callbacks may expect these values to always be >= 0. Currently it is possible for progress.size_dl and progress.size_ul to by set to a value of -1, if Curl_pgrsSetDownloadSize() or Curl_pgrsSetUploadSize() are passed a "size" of -1 (which a few places currently do, and a following patch will add more). So lets update Curl_pgrsSetDownloadSize() and Curl_pgrsSetUploadSize() so they make sure that these variables always contain a value that is >= 0. Updates test579 and test599.

2014-09-07multi.c: Avoid invalid memory read after free() from commit 3c8c873252Steve Holme
As the current element in the list is free()d by Curl_llist_remove(), when the associated connection is pending, reworked the loop to avoid accessing the next element through e->next afterward.

2014-09-06url.c: Use CURLAUTH_NONE constant rather than 0Steve Holme
Small follow up to commit 898808fa8c to use auth constants rather than hard code value when clearing picked authentication mechanism.
2014-09-04darwinssl: Use CopyCertSubject() to check CA cert.Vilmos Nebehaj
SecCertificateCopyPublicKey() is not available on iPhone. Use CopyCertSubject() instead to see if the certificate returned by SecCertificateCreateWithData() is valid. Reported-by: Toby Peterson
2014-09-02curl_multi_cleanup: remove superfluous NULL assignsDaniel Stenberg
... as the struct is free()d in the end anyway. It was first pointed out to me that one of the ->msglist assignments were supposed to have been ->pending but was a copy and paste mistake when I realized none of the clearing of pointers had to be there.
2014-09-02multi: convert CURLM_STATE_CONNECT_PEND handling to a listDaniel Stenberg
... instead of scanning through all handles, stash only the actual handles that are in that state in the new ->pending list and scan that list only. It should be mostly empty or very short. And only used for pipelining. This avoids a rather hefty slow-down especially notable if you add many handles to the same multi handle. Regression introduced in commit 0f147887 (version 7.30.0).
