Updated curl packages fix security vulnerabilities :

Paras Sethia discovered that libcurl would sometimes mix up multiple HTTP and HTTPS connections with NTLM authentication to the same server, sending requests for one user over the connection authenticated as a different user (CVE-2014-0015).

libcurl can in some circumstances re-use the wrong connection when asked to do transfers using other protocols than HTTP and FTP, causing a transfer that was initiated by an application to wrongfully re-use an existing connection to the same server that was authenticated using different credentials (CVE-2014-0138).

libcurl incorrectly validates wildcard SSL certificates containing literal IP addresses, so under certain conditions, it would allow and use a wildcard match specified in the CN field, allowing a malicious server to participate in a MITM attack or just fool users into believing that it is a legitimate site (CVE-2014-0139).

In cURL before 7.38.0, libcurl can be fooled to both sending cookies to wrong sites and into allowing arbitrary sites to set cookies for others. For this problem to trigger, the client application must use the numerical IP address in the URL to access the site (CVE-2014-3613).

In cURL before 7.38.0, 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 (CVE-2014-3620).

Symeon Paraschoudis discovered that the curl_easy_duphandle() function in cURL has a bug that can lead to libcurl eventually sending off sensitive data that was not intended for sending, while performing a HTTP POST operation. This bug requires CURLOPT_COPYPOSTFIELDS and curl_easy_duphandle() to be used in that order, and then the duplicate handle must be used to perform the HTTP POST. The curl command line tool is not affected by this problem as it does not use this sequence (CVE-2014-3707).

When libcurl sends a request to a server via a HTTP proxy, it copies the entire URL into the request and sends if off. If the given URL contains line feeds and carriage returns those will be sent along to the proxy too, which allows the program to for example send a separate HTTP request injected embedded in the URL (CVE-2014-8150).

- Update to 7.39.0

libcurl wrongly allows cookies to be set for TLDs, thus making them much broader then they are supposed to be allowed to. This can allow arbitrary sites to set cookies that then would get sent to a different and unrelated site or domain.

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.

- use only full matches for hosts used as IP address in     cookies (CVE-2014-3613)

    - reject incoming cookies set for top level domains       (CVE-2014-3620)

libcurl was updated to fix security issues :

CVE-2014-3613: Cookies for hosts specified by numeric IP could be assigned or used for other numeric IP hosts if portions of the numerics were the same.

CVE-2014-3620: libcurl allowed cookies to be set for toplevel domains, making them to broad.

Tim Ruehsen discovered that curl incorrectly handled partial literal IP addresses. This could lead to the disclosure of cookies to the wrong site, and malicious sites being able to set cookies for others.
(CVE-2014-3613)

Tim Ruehsen discovered that curl incorrectly allowed cookies to be set for Top Level Domains (TLDs). This could allow a malicious site to set a cookie that gets sent to other sites. (CVE-2014-3620).

Versions of cURL/libcURL older than 7.38.0 are unpatched for the following remote security bypass vulnerabilities due to errors in the way it handles cookies:

  - Handling of IP addresses in cookie domain when parsing received HTTP cookies can be leveraged to obtain sensitive information, such as HTTP cookies (CVE-2014-3613)

  - Failure to restrict libcurl-based HTTP clients from leaking cookie information, which can be leveraged by setting cookies to Top Level Domains (TLD) to bypass security restrictions to an unrelated site or domain (CVE-2014-3620)

Two vulnerabilities have been discovered in cURL, an URL transfer library. They can be use to leak cookie information :

  - 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.
