-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2015:098 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : curl Date : March 28, 2015 Affected: Business Server 2.0 _______________________________________________________________________ Problem Description: 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). _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0015 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0138 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0139 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3613 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3620 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3707 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-8150 http://advisories.mageia.org/MGASA-2014-0153.html http://advisories.mageia.org/MGASA-2014-0385.html http://advisories.mageia.org/MGASA-2014-0444.html http://advisories.mageia.org/MGASA-2015-0020.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 2/X86_64: 498d59be3a6a4ace215c0d98fb4abede mbs2/x86_64/curl-7.34.0-3.1.mbs2.x86_64.rpm 75a821b73a75ca34f1747a0f7479267f mbs2/x86_64/curl-examples-7.34.0-3.1.mbs2.noarch.rpm f5d3aad5f0fd9db68b87c648aaabbb4a mbs2/x86_64/lib64curl4-7.34.0-3.1.mbs2.x86_64.rpm 4f356a2c97f9f64124b4e8ebe307826a mbs2/x86_64/lib64curl-devel-7.34.0-3.1.mbs2.x86_64.rpm d010a357d76a8eb967c7c52f92fb35ae mbs2/SRPMS/curl-7.34.0-3.1.mbs2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
