The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 68.12. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-40 advisory.

  - When aborting an operation, such as a fetch, an abort signal may be deleted while alerting the objects to     be notified. This results in a use-after-free and we presume that with enough effort it could have been     exploited to run arbitrary code. (CVE-2020-15669)

  - If Thunderbird 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. (CVE-2020-15663)

  - By holding a reference to the <code>eval()</code> 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. (CVE-2020-15664)

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

This update was imported from the SUSE:SLE-15:Update update project.

The version of Firefox installed on the remote Windows host is prior to 80.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-36 advisory.

  - Mozilla developers Jason Kratzer, Christian Holler, and Byron Campen 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. (CVE-2020-15670)

  - If Firefox is installed to a user-writable directory, the Mozilla Maintenance Service would execute     updater.exe from the install location with administrative 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. (CVE-2020-15663)

  - By holding a reference to the <code>eval()</code> 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. (CVE-2020-15664)

  - During ECDSA signature generation, padding applied in the nonce designed to ensure constant-time scalar     multiplication was removed, resulting in variable-time execution dependent on secret data.
    (CVE-2020-12401)

  - When performing EC scalar point multiplication, the wNAF point multiplication algorithm was used; which     leaked partial information about the nonce used during signature generation. Given an electro-magnetic     trace of a few signature generations, the private key could have been computed. (CVE-2020-6829)

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

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.
