Detection & IOCsextracted from sources · hover to see the quote
- →Vulnerability is in WebKit's ArgumentsEliminationPhase::transform — specifically incorrect LoadVarargs handling where the node is removed regardless of whether the argumentCountIncludingThis limit condition is satisfied, leading to uninitialized values/length in the arguments object (CreateDirectArguments). ↗
- →PoC triggers the bug by JIT-compiling a function that calls a class constructor with a large spread of arguments (kArgsLength = 0x101 = 257 args) and checks for a corrupted arguments object length after ~0x3000 iterations with a 1-second sleep to allow JIT optimization. ↗
- →Exploitation vector is processing maliciously crafted web content via a crafted web site — remote, no user interaction beyond visiting the page. ↗
- →Affected component is WebKit across iOS (<10.3.3), Safari (<10.1.2), iCloud for Windows (<6.2.2), iTunes for Windows (<12.6.2), and tvOS (<10.2.2). Detection should focus on unpatched WebKit versions in these products. ↗
- ·The PoC uses a loop count of 0x100000 iterations with a deliberate 1-second sleep at iteration 0x3000 to trigger JIT compilation; exploitation reliability depends on JIT tier-up behavior which may vary across WebKit builds/platforms. ↗
- ·The vulnerability results in uninitialized memory values and length in the arguments object — actual code execution requires a further exploitation primitive beyond the memory corruption primitive demonstrated in the PoC. ↗

WebKitGTK+ vulnerabilities
vendor_ubuntu·2017-08-02
CVE-2017-2538 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.
