Detection & IOCsextracted from sources · hover to see the quote
- →CVE-2016-4622 is a WebKit memory corruption vulnerability in the Array.prototype.slice fast path (ArrayPrototype.cpp). The bug is triggered when the length check `length == toLength(exec, thisObj)` is bypassed, allowing `fastSlice` to be called with an inconsistent length, leading to out-of-bounds memory access. Detection should focus on JavaScript engine exploitation patterns targeting JSArray fastSlice. ↗
- →The vulnerability is triggered by visiting a maliciously crafted website; network-level detection should alert on exploitation attempts delivered via web content to WebKit-based browsers (Safari, iOS WebView, tvOS browser). ↗
- →Detailed exploitation technique for CVE-2016-4622 is publicly documented in a Phrack paper by saelo, meaning reliable public exploit primitives exist. Monitor for JavaScript payloads referencing Array slice manipulation patterns consistent with this write-up. ↗
- ·The vulnerability affects WebKit in Apple iOS before 9.3.3, Safari before 9.1.2, and tvOS before 9.2.2. Systems running these versions or unpatched WebKit (Debian fixed in webkit2gtk 2.12.4-1) remain vulnerable. ↗
- ·The root cause is in ArrayPrototype.cpp: the fast-path length consistency check (`length == toLength(exec, thisObj)`) must be present to prevent exploitation. Its absence (commented out) is the exploitable condition. ↗

CVE-2016-1854 WebKitGTK+ vulnerabilities
Title: WebKitGTK+ vulnerabilities
Summary: Several security issues were fixed in WebKitGTK+.
A large number of security issues were discovered in the WebKitGTK+ Web and
JavaScript engines. If a user were tricked into viewing a malicious
website, a remote attacker could exploit a variety of issues related to web
browser security, including cross-site scripting attacks, denial of service
attacks, and arbitrary code execution.
Instructions: This update uses a new upstream release, which includes additional bug
fixes. After a standard system update you need to restart any applications
that use WebKitGTK+, such as Epiphany, to make all the necessary changes.

## Abstract
Web browsers are integral parts of everyone's daily life.
They are commonly used
for security-critical and privacy sensitive tasks,
like banking transactions and checking medical records.
Unfortunately,
modern web browsers are
too complex to be bug free
( , 25 million lines of code in Chrome),
and their role as an interface to the cyberspace
makes them an attractive target for attacks.
Accordingly,
web browsers naturally
become an arena for demonstrating
advanced exploitation techni
