The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has firefox packages installed that are affected by multiple vulnerabilities:

  - 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)

  - 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)

  - 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)

  - 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)

  - 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)

  - 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)

  - 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)

  - 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. This vulnerability affects Firefox ESR < 68.12 and Thunderbird < 68.12.
    (CVE-2020-15669)

  - 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)

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

The remote NewStart CGSL host, running version MAIN 6.02, has thunderbird packages installed that are affected by multiple vulnerabilities:

  - 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-2020-15669)

  - 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 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)
