CVE-2018-12397

Mozilla: WebExtension local file permission check bypass

A WebExtension can request access to local files without the warning prompt stating that the extension will "Access your data for all websites" being displayed to the user. This allows extensions to run content scripts in local pages without permission warnings when a local file is opened. This vulnerability affects Firefox ESR < 60.3 and Firefox < 63.

CVE-2018-12386

Mozilla: type confusion in JavaScript

A vulnerability in register allocation in JavaScript can lead to type confusion, allowing for an arbitrary read and write. This leads to remote code execution inside the sandboxed content process when triggered. This vulnerability affects Firefox ESR < 60.2.2 and Firefox < 62.0.3.

CVE-2018-12387

Mozilla: stack out-of-bounds read in Array.prototype.push

A vulnerability where the JavaScript JIT compiler inlines Array.prototype.push with multiple arguments that results in the stack pointer being off by 8 bytes after a bailout. This leaks a memory address to the calling function which can be used as part of an exploit inside the sandboxed content process. This vulnerability affects Firefox ESR < 60.2.2 and Firefox < 62.0.3.

CVE-2018-12389

Mozilla: Memory safety bugs fixed in Firefox ESR 60.3

Mozilla developers and community members reported memory safety bugs present in Firefox ESR 60.2. 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 ESR < 60.3 and Thunderbird < 60.3.

CVE-2018-12367

Mozilla: Timing attack mitigation of PerformanceNavigationTiming

In the previous mitigations for Spectre, the resolution or precision of various methods was reduced to counteract the ability to measure precise time intervals. In that work PerformanceNavigationTiming was not adjusted but it was found that it could be used as a precision timer. This vulnerability affects Thunderbird < 60, Firefox ESR < 60.1, and Firefox < 61.

CVE-2014-1513

Mozilla: Out-of-bounds read/write through neutering ArrayBuffer objects (MFSA 2014-31)

TypedArrayObject.cpp in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 does not prevent a zero-length transition during use of an ArrayBuffer object, which allows remote attackers to execute arbitrary code or cause a denial of service (heap-based out-of-bounds write or read) via a crafted web site.
