"The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in
the SUSE-SU-2020:14456-1 advisory.

  - By observing the stack trace for JavaScript errors in web workers, it was possible to leak the result of a
    cross-origin redirect. This applied only to content that can be parsed as script. This vulnerability
    affects Firefox < 79, Firefox ESR < 68.11, Firefox ESR < 78.1, Thunderbird < 68.11, and Thunderbird <
    78.1. (CVE-2020-15652)

  - An iframe sandbox element with the allow-popups flag could be bypassed when using noopener links. This
    could have led to security issues for websites relying on sandbox configurations that allowed popups and
    hosted arbitrary content. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird <
    78.1. (CVE-2020-15653)

  - When in an endless loop, a website specifying a custom cursor using CSS could make it look like the user
    is interacting with the user interface, when they are not. This could lead to a perceived broken state,
    especially when interactions with existing browser dialogs and warnings do not work. This vulnerability
    affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. (CVE-2020-15654)

  - A redirected HTTP request which is observed or modified through a web extension could bypass existing CORS
    checks, leading to potential disclosure of cross-origin information. This vulnerability affects Firefox
    ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. (CVE-2020-15655)

  - JIT optimizations involving the Javascript arguments object could confuse later optimizations. This risk
    was already mitigated by various precautions in the code, resulting in this bug rated at only moderate
    severity. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1.
    (CVE-2020-15656)

  - Firefox could be made to load attacker-supplied DLL files from the installation directory. This required
    an attacker that is already capable of placing files in the installation directory. *Note: This issue only
    affected Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects
    Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. (CVE-2020-15657)

  - The code for downloading files did not properly take care of special characters, which led to an attacker
    being able to cut off the file ending at an earlier position, leading to a different file type being
    downloaded than shown in the dialog. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and
    Thunderbird < 78.1. (CVE-2020-15658)

  - Mozilla developers and community members reported memory safety bugs present in Firefox 78 and Firefox ESR
    78.0. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some
    of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 79, Firefox
    ESR < 68.11, Firefox ESR < 78.1, Thunderbird < 68.11, and Thunderbird < 78.1. (CVE-2020-15659)

  - Use after free in ANGLE in Google Chrome prior to 81.0.4044.122 allowed a remote attacker to potentially
    exploit heap corruption via a crafted HTML page. (CVE-2020-6463)

  - Inappropriate implementation in WebRTC in Google Chrome prior to 84.0.4147.89 allowed an attacker in a
    privileged network position to potentially exploit heap corruption via a crafted SCTP stream.
    (CVE-2020-6514)
