If an image had not loaded correctly (such as when it is not actually an image), it could be dragged and dropped cross-domain, resulting in a cross-origin information leak. This vulnerability affects Firefox < 71.

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

  - If an image had not loaded correctly (such as when it is not actually an image), it could be dragged and     dropped cross-domain, resulting in a cross-origin information leak. This vulnerability affects Firefox <     71. (CVE-2019-17014)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4216-2 advisory.

    USN-4216-1 fixed vulnerabilities in Firefox. This update provides the corresponding update for Ubuntu     16.04 LTS.



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 Ubuntu 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4216-1 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, obtain     sensitive information, or execute arbitrary code.

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 version of Firefox installed on the remote Windows host is prior to 71.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-36 advisory.

  - When encrypting with a block cipher, if a call to     NSC_EncryptUpdate was made with data smaller than the block     size, a small out of bounds write could occur. This could     have caused heap corruption and a potentially exploitable     crash. (CVE-2019-11745)

  - Improper refcounting of soft token session objects could     cause a use-after-free and crash (likely limited to a denial     of service). (CVE-2019-11756)

  - When setting a thread name on Windows in WebRTC, an     incorrect number of arguments could have been supplied,     leading to stack corruption and a potentially exploitable     crash.
    Note: this issue only occurs on Windows. Other operating     systems are unaffected. (CVE-2019-13722)

  - When using nested workers, a use-after-free could occur     during worker destruction. This resulted in a potentially     exploitable crash. (CVE-2019-17008)

  - When running, the updater service wrote status and log     files to an unrestricted location; potentially allowing     an unprivileged process to locate and exploit a     vulnerability in file handling in the updater service.
  - Note: This attack requires local system access and only     affects Windows. Other operating systems are not affected.
    (CVE-2019-17009)

  - Under certain conditions, when checking the Resist     Fingerprinting preference during device orientation checks,     a race condition could have caused a use-after-free and a     potentially exploitable crash. (CVE-2019-17010)

  - Under certain conditions, when retrieving a document from     a DocShell in the antitracking code, a race condition     could cause a use-after-free condition and a potentially     exploitable crash. (CVE-2019-17011)

  - Mozilla developers Christoph Diehl, Nathan Froyd, Jason     Kratzer, Christian Holler, Karl Tomlinson, Tyson Smith     reported memory safety bugs present in Firefox 70 and     Firefox ESR 68.2. 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-2019-17012)

  - Mozilla developers and community members Philipp, Diego     Calleja, Mikhail Gavrilov, Jason Kratzer, Christian     Holler, Markus Stange, Tyson Smith reported memory safety     bugs present in Firefox 70. 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-2019-17013)

  - If an image had not loaded correctly (such as when it is     not actually an image), it could be dragged and dropped     cross-domain, resulting in a cross-origin information leak.
    (CVE-2019-17014)     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 macOS or Mac OS X host is prior to 71.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-36 advisory.
