Detection & IOCsextracted from sources · hover to see the quote
- →Trigger condition is processing maliciously crafted web content delivered to a WebKitGTK-based application (e.g., Epiphany); monitor for memory corruption signals (crashes, heap anomalies) in WebKitGTK processes when rendering remote content. ↗
- →Vulnerable version boundary: WebKitGTK before 2.26.0 and WPE WebKit before 2.26.0. Detect unpatched installations by checking installed package versions against this threshold. ↗
- →On Debian/Ubuntu systems, confirm fix by verifying webkit2gtk package is at version 2.26.0-1 or later; flag hosts running older versions as exposed. ↗
- →After patching, restart all WebKitGTK+-dependent applications (e.g., Epiphany) to ensure the fix is active; running processes still using the old library remain exploitable. ↗
- ·Red Hat rates this as 'Moderate' severity because WebKitGTK is shipped only as a Gnome dependency, not as a standalone browser, reducing the practical attack surface on RHEL systems. ↗
- ·RHEL 6 (webkitgtk) is out of support scope and RHEL 7 (webkitgtk3) will not receive a fix for this CVE; detections on those platforms should account for permanently unpatched exposure. ↗

CVE-2019-8720 [HIGH] CWE-119 WebKitGTK Memory Corruption Vulnerability
Vulnerability: WebKitGTK Memory Corruption Vulnerability
Affected: WebKitGTK WebKitGTK
WebKitGTK contains a memory corruption vulnerability which can allow an attacker to perform remote code execution.
Required Action: Apply updates per vendor instructions.
Notes: https://nvd.nist.gov/vuln/detail/CVE-2019-8720

CVE-2019-8625 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.

CVE-2019-8720 [HIGH] CWE-119 webkitgtk: Multiple memory corruption issues leading to arbitrary code execution
webkitgtk: Multiple memory corruption issues leading to arbitrary code execution
A vulnerability was found in WebKit. The flaw is triggered when processing maliciously crafted web content that may lead to arbitrary code execution. Improved memory handling addresses the multiple memory corruption issues.
A vulnerability was found in WebKit. The flaw is triggered when processing maliciously crafted web content that may lead to arbitrary code execution. Improved memory handling addresses the multiple memory corruption issues.
Statement: This flaw is rated as 'Moderate' as the WebKitGTK package is shipped as a dependency for the Gnome package. Red Hat Enterprise Linux does not ship any WebKitGTK-based web browser where this flaw would present a higher severity major threat.
