The version of thunderbird installed on the remote host is prior to 68.9.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1468 advisory.

    The Mozilla Foundation Security Advisory describes this flaw as:

    If Thunderbird is configured to use STARTTLS for an IMAP server, and the server sends a PREAUTH response,     then Thunderbird will continue with an unencrypted connection, causing email data to be sent without     protection. (CVE-2020-12398)

    The Mozilla Foundation Security Advisory describes this flaw as:

    When browsing a malicious page, a race condition in our SharedWorkerService could occur and lead to a     potentially exploitable crash. (CVE-2020-12405)

    The Mozilla Foundation Security Advisory describes this flaw as:

    Mozilla developer Iain Ireland discovered a missing type check during unboxed objects removal, resulting     in a crash. We presume that with enough effort that it could be exploited to run arbitrary code.
    (CVE-2020-12406)

    The Mozilla Foundation Security Advisory describes this flaw as:

    Mozilla developers reported memory safety bugs present in Firefox 76 and Firefox ESR 68.8. 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-2020-12410)

    The Mozilla Foundation Security Advisory describes this flaw as:

    Due to confusion about ValueTags on JavaScript Objects, an object may pass through the type barrier,     resulting in memory corruption and a potentially exploitable crash. (CVE-2020-12417)

    The Mozilla Foundation Security Advisory describes this flaw as:

    Manipulating individual parts of a URL object could have caused an out-of-bounds read, leaking process     memory to malicious JavaScript. (CVE-2020-12418)

    The Mozilla Foundation Security Advisory describes this flaw as:

    When processing callbacks that occurred during window flushing in the parent process, the associated     window may die; causing a use-after-free condition. This could have led to memory corruption and a     potentially exploitable crash. (CVE-2020-12419)

    The Mozilla Foundation Security Advisory describes this flaw as:

    When trying to connect to a STUN server, a race condition could have caused a use-after-free of a pointer,     leading to memory corruption and a potentially exploitable crash. (CVE-2020-12420)

    The Mozilla Foundation Security Advisory describes this flaw as:

    When performing add-on updates, certificate chains terminating in non-built-in-roots were rejected (even     if they were legitimately added by an administrator.) This could have caused add-ons to become out-of-date     silently without notification to the user. (CVE-2020-12421)

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has thunderbird packages installed that are affected by multiple vulnerabilities:

  - Mozilla developers reported memory safety bugs present in Firefox 76 and Firefox ESR 68.8. 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 Thunderbird < 68.9.0, Firefox < 77, and     Firefox ESR < 68.9. (CVE-2020-12410)

  - Mozilla Developer Iain Ireland discovered a missing type check during unboxed objects removal, resulting     in a crash. We presume that with enough effort that it could be exploited to run arbitrary code. This     vulnerability affects Thunderbird < 68.9.0, Firefox < 77, and Firefox ESR < 68.9. (CVE-2020-12406)

  - When browsing a malicious page, a race condition in our SharedWorkerService could occur and lead to a     potentially exploitable crash. This vulnerability affects Thunderbird < 68.9.0, Firefox < 77, and Firefox     ESR < 68.9. (CVE-2020-12405)

  - If Thunderbird is configured to use STARTTLS for an IMAP server, and the server sends a PREAUTH response,     then Thunderbird will continue with an unencrypted connection, causing email data to be sent without     protection. This vulnerability affects Thunderbird < 68.9.0. (CVE-2020-12398)

  - Due to confusion about ValueTags on JavaScript Objects, an object may pass through the type barrier,     resulting in memory corruption and a potentially exploitable crash. *Note: this issue only affects Firefox     on ARM64 platforms.* This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird <     68.10.0. (CVE-2020-12417)

  - Manipulating individual parts of a URL object could have caused an out-of-bounds read, leaking process     memory to malicious JavaScript. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and     Thunderbird < 68.10.0. (CVE-2020-12418)

  - When processing callbacks that occurred during window flushing in the parent process, the associated     window may die; causing a use-after-free condition. This could have led to memory corruption and a     potentially exploitable crash. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and     Thunderbird < 68.10.0. (CVE-2020-12419)

  - When trying to connect to a STUN server, a race condition could have caused a use-after-free of a pointer,     leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR <     68.10, Firefox < 78, and Thunderbird < 68.10.0. (CVE-2020-12420)

  - When performing add-on updates, certificate chains terminating in non-built-in-roots were rejected (even     if they were legitimately added by an administrator.) This could have caused add-ons to become out-of-date     silently without notification to the user. This vulnerability affects Firefox ESR < 68.10, Firefox < 78,     and Thunderbird < 68.10.0. (CVE-2020-12421)

  - If an attacker intercepts Thunderbird's initial attempt to perform automatic account setup using the     Microsoft Exchange autodiscovery mechanism, and the attacker sends a crafted response, then Thunderbird     sends username and password over https to a server controlled by the attacker. This vulnerability affects     Thunderbird < 68.10.0. (CVE-2020-15646)

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 68.10. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-25 advisory.

The version of Firefox installed on the remote Windows host is prior to 78.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-24 advisory.

  - Mozilla developers and community members Bob Clary, Benjamin Bouvier, Calixte Denizet, Christian Holler     reported memory safety bugs present in Firefox 77. 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-2020-12426)

  - When <code>%2F</code> was present in a manifest URL, Firefox's AppCache behavior may have become confused     and allowed a manifest to be served from a subdirectory. This could cause the appcache to be used to     service requests for the top level directory. (CVE-2020-12415)

  - A <code>VideoStreamEncoder</code> may have been freed in a race condition with     <code>VideoBroadcaster::AddOrUpdateSink</code>, resulting in a use-after-free, memory corruption, and a     potentially exploitable crash. (CVE-2020-12416)

  - Due to confusion about ValueTags on JavaScript Objects, an object may pass through the type barrier,     resulting in memory corruption and a potentially exploitable crash. Note: this issue only affects Firefox     on ARM64 platforms. (CVE-2020-12417)
