During HTTP Live Stream playback on Firefox for Android, audio data can be accessed across origins in violation of security policies. Because the problem is in the underlying Android service, this issue is addressed by treating all HLS streams as cross-origin and opaque to access. *Note: this issue only affects Firefox for Android. Desktop versions of Firefox are unaffected.*. This vulnerability affects Firefox < 63, Firefox ESR < 60.3, and Thunderbird < 60.3.

This update for MozillaThunderbird fixes the following issues :

Thunderbird 63 ESR was updated to version 60.3.0 to fix the following issues (bsc#1112852) :

Security issues fixed (MFSA 2018-28) :

  - CVE-2018-12389: Fixed memory safety bugs.

  - CVE-2018-12390: Fixed memory safety bugs.

  - CVE-2018-12391: Fixed HTTP Live Stream audio data is     accessible cross-origin.

  - CVE-2018-12392: Fixed crash with nested event loops.

  - CVE-2018-12393: Fixed integer overflow during Unicode     conversion while loading JavaScript.

Non-security issues fixed :

  - various theme fixes

  - Shift+PageUp/PageDown in Write window

  - Gloda attachment filtering

  - Mailing list address auto-complete enter/return handling

  - Thunderbird hung if HTML signature references     non-existent image

  - Filters not working for headers that appear more than     once

Versions of Mozilla Firefox prior to 63 are unpatched for the following vulnerabilities as referenced in the mfsa2018-26 advisory:

 - A memory corruption bug exists that may lead to arbitrary code execution (CVE-2018-12388, CVE-2018-12390)
 - During HTTP Live Stream playback on Firefox for Android, audio data can be accessed across origins in violation of security policies. Because the problem is in the underlying Android service, this issue is addressed by treating all HLS streams as cross-origin and opaque to access. (CVE-2018-12391)
 - When manipulating user events in nested loops while opening a document through script, it is possible to trigger a potentially exploitable crash due to poor event handling. (CVE-2018-12392)
 - A potential vulnerability was found in 32-bit builds where an integer overflow during the conversion of scripts to an internal UTF-16 representation could result in allocating a buffer too small for the conversion. This leads to a possible out-of-bounds write. (CVE-2018-12393)
 - By rewriting the Host request headers using the webRequest API, a WebExtension can bypass domain restrictions through domain fronting. This would allow access to domains that share a host that are otherwise restricted. (CVE-2018-12395)
 - A vulnerability where a WebExtension can run content scripts in disallowed contexts following navigation or other events. This allows for potential privilege escalation by the WebExtension on sites where content scripts should not be run. (CVE-2018-12396)
 - A WebExtension can request access to local files without the warning prompt stating that the extension will 'Access your data for all websites' being displayed to the user. This allows extensions to run content scripts in local pages without permission warnings when a local file is opened. (CVE-2018-12397)
 - By using the reflected URL in some special resource URIs, such as chrome:, it is possible to inject stylesheets and bypass Content Security Policy (CSP). (CVE-2018-12398)
 - When a new protocol handler is registered, the API accepts a title argument which can be used to mislead users about which domain is registering the new protocol. This may result in the user approving a protocol handler that they otherwise would not have. (CVE-2018-12399)
 - In private browsing mode on Firefox for Android, favicons are cached in the cache/icons folder as they are in non-private mode. This allows information leakage of sites visited during private browsing sessions. (CVE-2018-12400)
 - Some special resource URIs will cause a non-exploitable crash if loaded with optional parameters following a '?' in the parsed string. This could lead to denial of service (DOS) attacks. (CVE-2018-12401)
 - SameSite cookies are sent on cross-origin requests when the 'Save Page As...' menu item is selected to save a page, violating cookie policy. This can result in saving the wrong version of resources based on those cookies. (CVE-2018-12402)
 - If a site is loaded over a HTTPS connection but loads a favicon resource over HTTP, the mixed content warning is not displayed to users. (CVE-2018-12403)

The remote host is affected by the vulnerability described in GLSA-201811-13 (Mozilla Thunderbird: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mozilla Thunderbird.
      Please review the referenced Mozilla Foundation Security Advisories and       CVE identifiers below for details.
  Impact :

    A remote attacker may be able to execute arbitrary code, cause a Denial       of Service condition, obtain sensitive information, or conduct Cross-Site       Request Forgery (CSRF).
  Workaround :

    There is no known workaround at this time.

The version of Mozilla Thunderbird installed on the remote Windows host is prior to 60.3. It is, therefore, affected by multiple vulnerabilities as noted in Mozilla Thunderbird stable channel update release notes for 2018/10/31. Please refer to the release notes for additional information. Note that Nessus has not attempted to exploit these issues but has instead relied only on the application's self- reported version number.
