Fix SIGSEGV on free'd easy_conn when pipe unexpectedly breaks
Fix data corruption issue with re-connected transfers
Fix use after free if we're completed but easy_conn not NULL
sending of the TSIZE option. I don't like fixing bugs just hours before
a release, but since it was broken and the patch fixes this for him I decided
to get it in anyway.
each test, so that the test suite can now be used to actually test the
verification of cert names etc. This made an error show up in the OpenSSL-
specific code where it would attempt to match the CN field even if a
subjectAltName exists that doesn't match. This is now fixed and verified
in test 311.
POSIX.1-2001. Note that RFC 2553 defines a prototype where the last parameter cnt is of type size_t.
Many systems follow RFC 2553. Glibc 2.0 and 2.1 have size_t, but 2.2 has socklen_t.
and the name length differ in those cases and thus leave the matching function
unmodified from before, as the matching functions never have to bother with
the zero bytes in legitimate cases. Peter Sylvester helped me realize that
this fix is slightly better as it leaves more code unmodified and makes the
detection a bit more obvious in the code.
should introduce an option to disable SNI, but as we're in feature freeze
now I've addressed the obvious bug here (pointed out by Peter Sylvester): we
shouldn't try to enable SNI when SSLv2 or SSLv3 is explicitly selected.
Code for OpenSSL and GnuTLS was fixed. NSS doesn't seem to have a particular
option for SNI, or are we simply not using it?
(http://curl.haxx.se/bug/view.cgi?id=2829955) mentioning the recent SSL cert
verification flaw found and exploited by Moxie Marlinspike. The presentation
he did at Black Hat is available here:
https://www.blackhat.com/html/bh-usa-09/bh-usa-09-archives.html#Marlinspike
Apparently at least one CA allowed a subjectAltName or CN that contain a
zero byte, and thus clients that assumed they would never have zero bytes
were exploited to OK a certificate that didn't actually match the site. Like
if the name in the cert was "example.com\0theatualsite.com", libcurl would
happily verify that cert for example.com.
libcurl now better use the length of the extracted name, not assuming it is
zero terminated.
only in some OpenSSL installs - like on Windows) isn't thread-safe and we
agreed that moving it to the global_init() function is a decent way to deal
with this situation.
CURLOPT_PREQUOTE) now accept a preceeding asterisk before the command to
send when using FTP, as a sign that libcurl shall simply ignore the response
from the server instead of treating it as an error. Not treating a 400+ FTP
response code as an error means that failed commands will not abort the
chain of commands, nor will they cause the connection to get disconnected.
"you replaced the old SSLeay_add_ssl_algorithms() call
with OpenSSL_add_all_algorithms(), however unlike the name suggests,
the second function is not a superset of the first. When using SSL
both these functions will need to be called in order to offer complete
functionality"
out that OpenSSL-powered libcurl didn't support the SHA-2 digest algorithm,
and provided the solution too: to use OpenSSL_add_all_algorithms() instead
of the older SSLeay_* alternative. OpenSSL_add_all_algorithms was added in
OpenSSL 0.9.5
in NSS-powered libcurl. Now the client certificates can be selected
automatically by a NSS built-in hook. Additionally pre-login to all PKCS11
slots is no more performed. It used to cause problems with HW tokens.
- Fixed reference counting for NSS client certificates. Now the PEM reader
module should be always properly unloaded on Curl_nss_cleanup(). If the unload
fails though, libcurl will try to reuse the already loaded instance.
(http://curl.haxx.se/bug/view.cgi?id=2813123) and an a patch that fixes the
problem:
Url A is accessed using auth. Url A redirects to Url B (on a different
server0. Url B reuses a persistent connection. Url B has auth, even though
it's on a different server.
Note: if Url B does not reuse a persistent connection, auth is not sent.
to use the "standard" ENABLE_IPV6 one. Also, if port number cannot be figured
out to connect to after a name resolve (due to it not being IPv4 or IPv6),
that particular address will now simply be skipped.
don't know how they got wrong in the first place, but using this output
format makes it possible to quite easily separate the string into an array
of multiple items.
