Summary
unity-firefox-extension, webapps-greasemonkey, webaccounts-browser-extension update
Details

USN-2743-1 fixed vulnerabilities in Firefox. Future Firefox updates will require all addons be signed and unity-firefox-extension, webapps-greasemonkey and webaccounts-browser-extension will not go through the signing process. Because these addons currently break search engine installations (LP:

1069793), this update permanently disables the addons by removing them from

the system.

We apologize for any inconvenience.

Original advisory details:

Andrew Osmond, Olli Pettay, Andrew Sutherland, Christian Holler, David Major, Andrew McCreight, Cameron McCormack, Bob Clary and Randell Jesup discovered multiple memory safety issues 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 via application crash, or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2015-4500, CVE-2015-4501)

André Bargull discovered that when a web page creates a scripted proxy for the window with a handler defined a certain way, a reference to the inner window will be passed, rather than that of the outer window. (CVE-2015-4502)

Felix Gröbert discovered an out-of-bounds read in the QCMS color management library in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via application crash, or obtain sensitive information. (CVE-2015-4504)

Khalil Zhani discovered a buffer overflow when parsing VP9 content in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2015-4506)

Spandan Veggalam discovered a crash while using the debugger API in some circumstances. If a user were tricked in to opening a specially crafted website whilst using the debugger, an attacker could potentially exploit this to execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2015-4507)

Juho Nurminen discovered that the URL bar could display the wrong URL in reader mode in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to conduct URL spoofing attacks. (CVE-2015-4508)

A use-after-free was discovered when manipulating HTML media content in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2015-4509)

Looben Yang discovered a use-after-free when using a shared worker with IndexedDB in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2015-4510)

Francisco Alonso discovered an out-of-bounds read during 2D canvas rendering in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to obtain sensitive information. (CVE-2015-4512)

Jeff Walden discovered that changes could be made to immutable properties in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to execute arbitrary script in a privileged scope. (CVE-2015-4516)

Ronald Crane reported multiple vulnerabilities. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2015-4517, CVE-2015-4521, CVE-2015-4522, CVE-2015-7174, CVE-2015-7175, CVE-2015-7176, CVE-2015-7177, CVE-2015-7180)

Mario Gomes discovered that dragging and dropping an image after a redirect exposes the redirected URL to scripts. An attacker could potentially exploit this to obtain sensitive information. (CVE-2015-4519)

Ehsan Akhgari discovered 2 issues with CORS preflight requests. An attacker could potentially exploit these to bypass CORS restrictions. (CVE-2015-4520)

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Sightings

Author Source Type Date Other

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
