The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2020:14489-1 advisory.

  - If Firefox is installed to a user-writable directory, the Mozilla Maintenance Service would execute     updater.exe from the install location with system privileges. Although the Mozilla Maintenance Service     does ensure that updater.exe is signed by Mozilla, the version could have been rolled back to a previous     version which would have allowed exploitation of an older bug and arbitrary code execution with System     Privileges. *Note: This issue only affected Windows operating systems. Other operating systems are     unaffected.*. This vulnerability affects Firefox < 80, Thunderbird < 78.2, Thunderbird < 68.12, Firefox     ESR < 68.12, and Firefox ESR < 78.2. (CVE-2020-15663)

  - By holding a reference to the eval() function from an about:blank window, a malicious webpage could have     gained access to the InstallTrigger object which would allow them to prompt the user to install an     extension. Combined with user confusion, this could result in an unintended or malicious extension being     installed. This vulnerability affects Firefox < 80, Thunderbird < 78.2, Thunderbird < 68.12, Firefox ESR <     68.12, Firefox ESR < 78.2, and Firefox for Android < 80. (CVE-2020-15664)

  - Mozilla developers reported memory safety bugs present in Firefox for Android 79. 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 < 80, Firefox ESR < 78.2, Thunderbird     < 78.2, and Firefox for Android < 80. (CVE-2020-15670)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 78.2. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-41 advisory. Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4474-1 advisory.

    Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially     crafted website, an attacker could potentially exploit these to cause a denial of service, trick the user     in to installing a malicious extension, spoof the URL bar, leak sensitive information between origins, or     execute arbitrary code. (CVE-2020-15664, CVE-2020-15665, CVE-2020-15666, CVE-2020-15670)

    It was discovered that NSS incorrectly handled certain signatures. An attacker could possibly use this     issue to expose sensitive information. (CVE-2020-12400, CVE-2020-12401, CVE-2020-6829)

    A data race was discovered when importing certificate information in to the trust store. An attacker could     potentially exploit this to cause an unspecified impact. (CVE-2020-15668)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of Firefox ESR installed on the remote Windows host is prior to 78.2. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-38 advisory.

  - Mozilla developers Jason Kratzer, Christian Holler, Byron Campen, Tyson Smith reported memory safety bugs     present in Firefox 79 and Firefox ESR 78.1. 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.
