The remote CentOS Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the CESA-2020:2828 advisory.

  - Mozilla: Memory corruption due to missing sign-extension for ValueTags on ARM64 (CVE-2020-12417)

  - Mozilla: Information disclosure due to manipulated URL object (CVE-2020-12418)

  - Mozilla: Use-after-free in nsGlobalWindowInner (CVE-2020-12419)

  - Mozilla: Use-After-Free when trying to connect to a STUN server (CVE-2020-12420)

  - Mozilla: Add-On updates did not respect the same certificate trust rules as software updates     (CVE-2020-12421)

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

The remote CentOS Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2020:2966 advisory.

  - 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 This could have caused add-ons to become out-of-date     silently without notification to the user.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 these issues 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-4421-1 advisory.

    Multiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially     crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of     service, obtain sensitive information, or execute arbtirary code. (CVE-2020-12405, CVE-2020-12406,     CVE-2020-12410, CVE-2020-12417, CVE-2020-12418, CVE-2020-12419, CVE-2020-12420)

    It was discovered that Thunderbird would continue an unencrypted connection when configured to use     STARTTLS for IMAP if the server responded with PREAUTH. A remote attacker could potentially exploit this     to perform a person-in-the-middle attack in order to obtain sensitive information. (CVE-2020-12398)

    It was discovered that NSS showed timing differences when performing DSA signatures. An attacker could     potentially exploit this to obtain private keys using a timing attack. (CVE-2020-12399)

    It was discovered that when performing add-on updates, certificate chains not terminating with built-in     roots were silently rejected. This could result in add-ons becoming outdated. (CVE-2020-12421)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

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

  - 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)

  - 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)

  - 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)

  - 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)

  - 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)
