Cross-site scripting (XSS) vulnerability in Mozilla Thunderbird 17.x through 17.0.8, Thunderbird ESR 17.x through 17.0.10, and SeaMonkey before 2.20 allows user-assisted remote attackers to inject arbitrary web script or HTML via an e-mail message containing a data: URL in a (1) OBJECT or (2) EMBED element, a related issue to CVE-2013-6674.

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

  - Cross-site scripting (XSS) vulnerability in Mozilla Thunderbird 17.x through 17.0.8, Thunderbird ESR 17.x     through 17.0.10, and SeaMonkey before 2.20 allows user-assisted remote attackers to inject arbitrary web     script or HTML via an e-mail message containing a data: URL in a (1) OBJECT or (2) EMBED element, a     related issue to CVE-2013-6674. (CVE-2014-2018)

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

Versions of Mozilla Thunderbird prior to 17.0.8 are affected by the following vulnerabilities :

 - A flaw exists because the program does not validate URLs in IFRAME elements before returning it to users.
 - A flaw exists because the program does not validate input when handling a specially crafted EMBED or OBJECT element.

These vulnerabilities may allow a context-dependent attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server.

The installed version of Thunderbird is 17.x or later but prior to 24. It is, therefore, potentially affected the following vulnerabilities:

  - Memory issues exist in the browser engine that could     allow for denial of service or arbitrary code execution.
    (CVE-2013-1718, CVE-2013-1719)

  - The HTML5 Tree Builder does not properly maintain     states, which could result in a denial of service or     possible arbitrary code execution.  (CVE-2013-1720)

  - The ANGLE library is vulnerable to an integer overflow,     which could result in a denial of service or arbitrary     code execution. (CVE-2013-1721)

  - Multiple use-after-free problems exist, which could     result in denial of service attacks or arbitrary code     execution. (CVE-2013-1722, CVE-2013-1724,     CVE-2013-1735, CVE-2013-1736, CVE-2013-1738)

  - The NativeKey widget does not properly terminate key     messages, possibly leading to a denial of service attack.
    (CVE-2013-1723)

  - Incorrect scope handling for JavaScript objects with     compartments could result in denial of service or     possibly arbitrary code execution. (CVE-2013-1725)

  - Local users can gain the same privileges as the Mozilla     Updater because the application does not ensure     exclusive access to the update file. An attacker could     exploit this by inserting a malicious file into the     update file. (CVE-2013-1726)

  - Sensitive information can be obtained via unspecified     vectors because the IonMonkey JavaScript does not     properly initialize memory. (CVE-2013-1728)

  - A JavaScript compartment mismatch could result in a     denial of service or arbitrary code execution. Versions     of Firefox 20 or greater are not susceptible to the     arbitrary code execution mentioned above.
    (CVE-2013-1730)

  - A buffer overflow is possible because of an issue with     multi-column layouts. (CVE-2013-1732)

  - An object is not properly identified during use of     user-defined getter methods on DOM proxies.  This could     result in access restrictions being bypassed.
    (CVE-2013-1737)

  - An input validation error exists related to email     messages containing HTML and iframes and the action of     replying to or forwarding such messages that could     allow cross-site scripting attacks. (CVE-2013-6674)

  - An input validation error exists related to email     messages containing HTML and object or embed elements     that could allow cross-site scripting attacks.
    (CVE-2014-2018)

The installed version of Thunderbird is a version prior to 24.0.
It is, therefore, potentially affected by the following vulnerabilities :

    (CVE-2014-2018)

Versions of SeaMonkey earlier than version 2.20 are prone to the following vulnerabilities :

 - Multiple memory-corruption vulnerabilities exist in the browser engine that could lead to arbitrary code execution. (CVE-2013-1701, CVE-2013-1702)

 - A remote code execution and cross-site scripting vulnerability occurs when generating a Certificate Request Message Format (CRMF) request. (CVE-2013-1710)
 - A cross-site scripting vulnerability occurs by bypassing XrayWrappers from within the Chrome on unprivileged objects, using XBL Scopes. (CVE-2013-1711)
 - A privilege-escalation vulnerability occurs due to an error when using Mozilla Updater. An attacker can exploit this issue to load a specific malicious DLL file from the local system using the Mozilla Updater, and can able to execute the DLL in a privileged context through the Mozilla Maintenance Service's privileges. (CVE-2013-1712)
 - A same-origin security-bypass vulnerability exists because wrong principal is used for validating URI for some Javascript components. (CVE-2013-1713)
 - A same-origin security-bypass vulnerability occurs due to an error with web workers and XMLHttpRequest. (CVE-2013-1714)
 - An information-disclosure vulnerability occurs due to an unspecified error with Java applets. This issue leads to disclose contents of local file system when loaded using the a 'file:/// URI'. (CVE-2013-1717)
 - Stored cross-site scripting vulnerability due to insufficient input validation of 'data:' URLs in iframe elements. (CVE-2013-6674)

  - An unspecified error exists related to generating     'Certificate Request Message Format' (CRMF) requests     that could allow cross-site scripting attacks.
    (CVE-2013-1710)
