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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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 relies on the presence of the package as reported by the vendor.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - 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)

  - 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. This vulnerability affects
    Firefox < 80 and Firefox for Android < 80. (CVE-2020-6829)

  - When converting coordinates from projective to affine, the modular inversion was not performed in constant
    time, resulting in a possible timing-based side channel attack. This vulnerability affects Firefox < 80
    and Firefox for Android < 80. (CVE-2020-12400)

  - 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. This
    vulnerability affects Firefox < 80 and Firefox for Android < 80. (CVE-2020-12401)

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - 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)

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.

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)

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

The version of Thunderbird installed on the remote Windows host is prior to 78.2. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-41 advisory.

  - Mozilla developers Jason Kratzer, Christian Holler, Byron Campen, Tyson Smith reported memory safety bugs     present in Thunderbird 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)
