  - CVE-2014-3613
    By not detecting and rejecting domain names for partial
    literal IP addresses properly when parsing received HTTP
    cookies, libcurl can be fooled to both sending cookies
    to wrong sites and into allowing arbitrary sites to set
    cookies for others.

  - CVE-2014-3620
    libcurl wrongly allows cookies to be set for Top Level
    Domains (TLDs), thus making them apply broader than
    cookies are allowed. This can allow arbitrary sites to
    set cookies that then would get sent to a different and
    unrelated site or domain."

"Updated curl packages that fix multiple security issues, several bugs,
and add two enhancements are now available for Red Hat Enterprise
Linux 7.

Red Hat Product Security has rated this update as having Moderate
security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

The curl packages provide the libcurl library and the curl utility for
downloading files from servers using various protocols, including
HTTP, FTP, and LDAP.

It was found that the libcurl library did not correctly handle partial
literal IP addresses when parsing received HTTP cookies. An attacker
able to trick a user into connecting to a malicious server could use
this flaw to set the user's cookie to a crafted domain, making other
cookie-related issues easier to exploit. (CVE-2014-3613)

A flaw was found in the way the libcurl library performed the
duplication of connection handles. If an application set the
CURLOPT_COPYPOSTFIELDS option for a handle, using the handle's
duplicate could cause the application to crash or disclose a portion
of its memory. (CVE-2014-3707)

It was discovered that the libcurl library failed to properly handle
URLs with embedded end-of-line characters. An attacker able to make an
application using libcurl access a specially crafted URL via an HTTP
proxy could use this flaw to inject additional headers to the request
or construct additional requests. (CVE-2014-8150)

It was discovered that libcurl implemented aspects of the NTLM and
Negotiate authentication incorrectly. If an application uses libcurl
and the affected mechanisms in a specific way, certain requests to a
previously NTLM-authenticated server could appears as sent by the
wrong authenticated user. Additionally, the initial set of credentials
for HTTP Negotiate-authenticated requests could be reused in
subsequent requests, although a different set of credentials was
specified. (CVE-2015-3143, CVE-2015-3148)

Red Hat would like to thank the cURL project for reporting these
issues.

Bug fixes :

* An out-of-protocol fallback to SSL 3.0 was available with libcurl.
Attackers could abuse the fallback to force downgrade of the SSL
version. The fallback has been removed from libcurl. Users requiring
this functionality can explicitly enable SSL 3.0 through the libcurl
API. (BZ#1154060)

* TLS 1.1 and TLS 1.2 are no longer disabled by default in libcurl.
You can explicitly disable them through the libcurl API. (BZ#1170339)

* FTP operations such as downloading files took a significantly long
time to complete. Now, the FTP implementation in libcurl correctly
sets blocking direction and estimated timeout for connections,
resulting in faster FTP transfers. (BZ#1218272)

Enhancements :

* With the updated packages, it is possible to explicitly enable or
disable new Advanced Encryption Standard (AES) cipher suites to be
used for the TLS protocol. (BZ#1066065)

* The libcurl library did not implement a non-blocking SSL handshake,
which negatively affected performance of applications based on the
libcurl multi API. The non-blocking SSL handshake has been implemented
in libcurl, and the libcurl multi API now immediately returns the
control back to the application whenever it cannot read or write data
from or to the underlying network socket. (BZ#1091429)

* The libcurl library used an unnecessarily long blocking delay for
actions with no active file descriptors, even for short operations.
Some actions, such as resolving a host name using /etc/hosts, took a
long time to complete. The blocking code in libcurl has been modified
so that the initial delay is short and gradually increases until an
event occurs. (BZ#1130239)

All curl users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues and add these
enhancements."
