Mozilla developers and community members reported memory safety bugs present in Firefox 63. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox < 64.

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

  - Mozilla developers and community members reported memory safety bugs present in Firefox 63. Some of these     bugs showed evidence of memory corruption and we presume that with enough effort that some of these could     be exploited to run arbitrary code. This vulnerability affects Firefox < 64. (CVE-2018-12406)

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

The version of Firefox installed on the remote macOS or Mac OS X host is prior to 64.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2018-29 advisory.

  - A potential vulnerability leading to an integer overflow can occur during buffer size calculations for     images when a raw value is used instead of the checked value. This can lead to an out-of-bounds write.
    (CVE-2018-18498)

  - A buffer overflow occurs when drawing and validating elements with the ANGLE graphics library, used for     WebGL content, when working with the <code>VertexBuffer11</code> module. This results in a potentially     exploitable crash. (CVE-2018-12407)

  - A buffer overflow and out-of-bounds read can occur in <code>TextureStorage11</code> within the ANGLE     graphics library, used for WebGL content. This results in a potentially exploitable crash.
    (CVE-2018-17466)

  - A use-after-free vulnerability can occur after deleting a selection element due to a weak reference to the     <code>select</code> element in the <code>options</code> collection. This results in a potentially     exploitable crash. (CVE-2018-18492)

  - A buffer overflow can occur in the Skia library during buffer offset calculations with hardware     accelerated canvas 2D actions due to the use of 32-bit calculations instead of 64-bit. This results in a     potentially exploitable crash. (CVE-2018-18493)

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

Versions of Mozilla Firefox prior to 64 are unpatched for the following vulnerabilities as referenced in the mfsa2018-29 advisory:

 - A memory safety bug was reported that showed evidence of memory corruption that with enough effort could be exploited to run arbitrary code. (CVE-2018-12405, CVE-2018-12406)
 - A buffer overflow occurs when drawing and validating elements with the ANGLE graphics library, used for WebGL content, when working with the 'VertexBuffer11' module. This results in a potentially exploitable crash. (CVE-2018-12407)
 - A buffer overflow and out-of-bounds read can occur in 'TextureStorage11' within the ANGLE graphics library, used for WebGL content. This results in a potentially exploitable crash. (CVE-2018-17466)
 - A use-after-free vulnerability can occur after deleting a selection element due to a weak reference to the select element in the options collection. This results in a potentially exploitable crash. (CVE-2018-18492)
 - A buffer overflow can occur in the Skia library during buffer offset calculations with hardware accelerated canvas 2D actions due to the use of 32-bit calculations instead of 64-bit. This results in a potentially exploitable crash. (CVE-2018-18493)
 - A same-origin policy violation allowing the theft of cross-origin URL entries when using the Javascript location property to cause a redirection to another site using 'performance.getEntries()'. This is a same-origin policy violation and could allow for data theft. (CVE-2018-18494)
 - WebExtension content scripts can be loaded into 'about:' pages in some circumstances, in violation of the permissions granted to extensions. This could allow an extension to interfere with the loading and usage of these pages and use capabilities that were intended to be restricted from extensions. (CVE-2018-18495)
 - When the RSS Feed preview 'about:feeds' page is framed within another page, it can be used in concert with scripted content for a clickjacking attack that confuses users into downloading and executing an executable file from a temporary directory. (CVE-2018-18496)
 - Limitations on the URIs allowed to WebExtensions by the 'browser.windows.create' API can be bypassed when a pipe in the URL field is used within the extension to load multiple pages as a single argument. This could allow a malicious WebExtension to opened privileged 'about:' or 'file:' locations. (CVE-2018-18497)
 - A potential vulnerability leading to an integer overflow can occur during buffer size calculations for images when a raw value is used instead of the checked value. This can lead to an out-of-bounds write. (CVE-2018-18498)
 - The 'about:crashcontent' and 'about:crashparent' pages can be triggered by web content. These pages are used to crash the loaded page or the browser for test purposes. This issue allows for a non-persistent denial of service (DOS) attack by a malicious site which links to these pages. (CVE-2018-18510)

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3844-1 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, bypass same-     origin restritions, or execute arbitrary code. (CVE-2018-12405, CVE-2018-12406, CVE-2018-12407,     CVE-2018-17466, CVE-2018-18492, CVE-2018-18493, CVE-2018-18494, CVE-2018-18498)

    Multiple security issues were discovered in WebExtensions. If a user were tricked in to installing a     specially crafted extension, an attacker could potentially exploit these to open privileged pages, or     bypass other security restrictions. (CVE-2018-18495, CVE-2018-18497)

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.
