The remote VMware ESXi host is version 5.1 prior to build 2323236. It is, therefore, affected by the following vulnerabilities in bundled third-party libraries :

  - Multiple vulnerabilities exist in the bundled Python     library. (CVE-2011-3389, CVE-2012-0845, CVE-2012-0876,     CVE-2012-1150, CVE-2013-1752, CVE-2013-4238)

  - Multiple vulnerabilities exist in the bundled GNU C     Library (glibc). (CVE-2013-0242, CVE-2013-1914,     CVE-2013-4332)

  - Multiple vulnerabilities exist in the bundled XML     Parser library (libxml2). (CVE-2013-2877, CVE-2014-0191)

  - Multiple vulnerabilities exist in the bundled cURL     library (libcurl). (CVE-2014-0015, CVE-2014-0138)

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).

The remote VMware ESXi host is affected by multiple vulnerabilities :

  - Multiple denial of service vulnerabilities exist in     Python function _read_status() in library httplib and     in function readline() in libraries smtplib, ftplib,     nntplib, imaplib, and poplib. A remote attacker can     exploit these vulnerabilities to crash the module.
    (CVE-2013-1752)

  - A out-of-bounds read error exists in file parser.c in     library libxml2 due to a failure to properly check the     XML_PARSER_EOF state. An unauthenticated, remote     attacker can exploit this, via a crafted document that     abruptly ends, to cause a denial of service.
    (CVE-2013-2877)

  - A spoofing vulnerability exists in the Python SSL module     in the ssl.match_hostname() function due to improper     handling of the NULL character ('\0') in a domain name     in the Subject Alternative Name field of an X.509     certificate. A man-in-the-middle attacker can exploit     this, via a crafted certificate issued by a legitimate     certification authority, to spoof arbitrary SSL servers.
    (CVE-2013-4238)

  - cURL and libcurl are affected by a flaw related to the     re-use of NTLM connections whenever more than one     authentication method is enabled. An unauthenticated,     remote attacker can exploit this, via a crafted request,     to connect and impersonate other users. (CVE-2014-0015)

  - The default configuration in cURL and libcurl reuses the     SCP, SFTP, POP3, POP3S, IMAP, IMAPS, SMTP, SMTPS, LDAP,     and LDAPS connections. An unauthenticated, remote     attacker can exploit this, via a crafted request, to     connect and impersonate other users. (CVE-2014-0138)

  - A flaw exists in the xmlParserHandlePEReference()     function in file parser.c in libxml2 due to loading     external entities regardless of entity substitution or     validation being enabled. An unauthenticated, remote     attacker can exploit this, via a crafted XML document,     to exhaust resources, resulting in a denial of service.
    (CVE-2014-0191)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - cURL and libcurl 7.10.6 through 7.34.0, when more than one authentication method is enabled, re-uses NTLM     connections, which might allow context-dependent attackers to authenticate as other users via a request.
    (CVE-2014-0015)

Note that Nessus relies on the presence of the package as reported by the vendor.

Updated curl packages that fix two security issues and several bugs are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team 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.

cURL provides the libcurl library and a command line tool for downloading files from servers using various protocols, including HTTP, FTP, and LDAP.

It was found that libcurl could incorrectly reuse existing connections for requests that should have used different or no authentication credentials, when using one of the following protocols: HTTP(S) with NTLM authentication, LDAP(S), SCP, or SFTP. If an application using the libcurl library connected to a remote server with certain authentication credentials, this flaw could cause other requests to use those same credentials. (CVE-2014-0015, CVE-2014-0138)

Red Hat would like to thank the cURL project for reporting these issues. Upstream acknowledges Paras Sethia as the original reporter of CVE-2014-0015 and Yehezkel Horowitz for discovering the security impact of this issue, and Steve Holme as the original reporter of CVE-2014-0138.

This update also fixes the following bugs :

* Previously, the libcurl library was closing a network socket without first terminating the SSL connection using the socket. This resulted in a write after close and consequent leakage of memory dynamically allocated by the SSL library. An upstream patch has been applied on libcurl to fix this bug. As a result, the write after close no longer happens, and the SSL library no longer leaks memory. (BZ#1092479)

* Previously, the libcurl library did not implement a non-blocking SSL handshake, which negatively affected performance of applications based on libcurl's multi API. To fix this bug, the non-blocking SSL handshake has been implemented by libcurl. With this update, libcurl's multi API immediately returns the control back to the application whenever it cannot read/write data from/to the underlying network socket. (BZ#1092480)

* Previously, the curl package could not be rebuilt from sources due to an expired cookie in the upstream test-suite, which runs during the build. An upstream patch has been applied to postpone the expiration date of the cookie, which makes it possible to rebuild the package from sources again. (BZ#1092486)

* Previously, the libcurl library attempted to authenticate using Kerberos whenever such an authentication method was offered by the server. This caused problems when the server offered multiple authentication methods and Kerberos was not the selected one. An upstream patch has been applied on libcurl to fix this bug. Now libcurl no longer uses Kerberos authentication if another authentication method is selected. (BZ#1096797)

All curl users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. All running applications that use libcurl have to be restarted for this update to take effect.

a. VMware vCSA cross-site scripting vulnerability

   VMware vCenter Server Appliance (vCSA) contains a vulnerability    that may allow for Cross Site Scripting. Exploitation of this    vulnerability in vCenter Server requires tricking a user to click    on a malicious link or to open a malicious web page.
