New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote macOS or Mac OS X host contains a web browser that is affected by multiple vulnerabilities.
DescriptionThe version of Mozilla Firefox installed on the remote macOS or Mac OS X host is prior to 52.0. It is, therefore, affected by multiple vulnerabilities :
- Mozilla developers and community members Boris Zbarsky, Christian Holler, Honza Bambas, Jon Coppeard, Randell Jesup, Andre Bargull, Kan-Ru Chen, and Nathan Froyd reported memory safety bugs present in Firefox 51 and Firefox ESR 45.7. 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. (CVE-2017-5398)
- Mozilla developers and community members Carsten Book, Calixte Denizet, Christian Holler, Andrew McCreight, David Bolter, David Keeler, Jon Coppeard, Tyson Smith, Ronald Crane, Tooru Fujisawa, Ben Kelly, Bob Owen, Jed Davis, Julian Seward, Julian Hector, Philipp, Markus Stange, and Andre Bargull reported memory safety bugs present in Firefox 51. 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. (CVE-2017-5399)
- JIT-spray targeting asm.js combined with a heap spray allows for a bypass of ASLR and DEP protections leading to potential memory corruption attacks. (CVE-2017-5400)
- A crash triggerable by web content in which an ErrorResult references unassigned memory due to a logic error. The resulting crash may be exploitable.
- A use-after-free can occur when events are fired for a FontFace object after the object has been already been destroyed while working with fonts. This results in a potentially exploitable crash. (CVE-2017-5402)
- When adding a range to an object in the DOM, it is possible to use addRange to add the range to an incorrect root object. This triggers a use-after-free, resulting in a potentially exploitable crash.
- A use-after-free error can occur when manipulating ranges in selections with one node inside a native anonymous tree and one node outside of it. This results in a potentially exploitable crash. (CVE-2017-5404)
- Certain response codes in FTP connections can result in the use of uninitialized values for ports in FTP operations. (CVE-2017-5405)
- A segmentation fault can occur in the Skia graphics library during some canvas operations due to issues with mask/clip intersection and empty masks.
- Using SVG filters that don't use the fixed point math implementation on a target iframe, a malicious page can extract pixel values from a targeted user. This can be used to extract history information and read text values across domains. This violates same-origin policy and leads to information disclosure. (CVE-2017-5407)
- Video files loaded video captions cross-origin without checking for the presence of CORS headers permitting such cross-origin use, leading to potential information disclosure for video captions. (CVE-2017-5408)
- A buffer overflow read during SVG filter color value operations, resulting in data exposure. (CVE-2017-5412)
- A segmentation fault can occur during some bidirectional layout operations. (CVE-2017-5413)
- The file picker dialog can choose and display the wrong local default directory when instantiated. On some operating systems, this can lead to information disclosure, such as the operating system or the local account name. (CVE-2017-5414)
- An attack can use a blob URL and script to spoof an arbitrary addressbar URL prefaced by blob: as the protocol, leading to user confusion and further spoofing attacks. (CVE-2017-5415)
- In certain circumstances a networking event listener can be prematurely released. This appears to result in a null dereference in practice. (CVE-2017-5416)
- When dragging content from the primary browser pane to the addressbar on a malicious site, it is possible to change the addressbar so that the displayed location following navigation does not match the URL of the newly loaded page. This allows for spoofing attacks.
- An out of bounds read error occurs when parsing some HTTP digest authorization responses, resulting in information leakage through the reading of random memory containing matches to specifically set patterns.
- If a malicious site repeatedly triggers a modal authentication prompt, eventually the browser UI will become non-responsive, requiring shutdown through the operating system. This is a denial of service (DOS) attack. (CVE-2017-5419)
- A malicious site could spoof the contents of the print preview window if popup windows are enabled, resulting in user confusion of what site is currently loaded.
- If a malicious site uses the view-source: protocol in a series within a single hyperlink, it can trigger a non-exploitable browser crash when the hyperlink is selected. This was fixed by no longer making view-source: linkable. (CVE-2017-5422)
- The Gecko Media Plugin sandbox allows access to local files that match specific regular expressions. On OS OX, this matching allows access to some data in subdirectories of /private/var that could expose personal or temporary data. This has been updated to not allow access to /private/var and its subdirectories. Note: this issue only affects OS X.
Other operating systems are not affected.
- A non-existent chrome.manifest file will attempt to be loaded during startup from the primary installation directory. If a malicious user with local access puts chrome.manifest and other referenced files in this directory, they will be loaded and activated during startup. This could result in malicious software being added without consent or modification of referenced installed files. (CVE-2017-5427)

Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpgrade to Mozilla Firefox version 52.0 or later.
