webkit2gtk vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.04 LTS
Summary:
Several security issues were fixed in WebKitGTK+.
Software Description: - webkit2gtk: Web content engine library for GTK+
Details:
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.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 18.04 LTS: libjavascriptcoregtk-4.0-18 2.22.2-0ubuntu0.18.04.1 libwebkit2gtk-4.0-37 2.22.2-0ubuntu0.18.04.1
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.

If a user were tricked into viewing a malicious\nwebsite, a remote attacker could exploit a variety of issues related to web\nbrowser security, including cross-site scripting attacks, denial of service\nattacks, and arbitrary code execution. \n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 18.04 LTS:\n libjavascriptcoregtk-4.0-18 2.22.2-0ubuntu0.18.04.1\n libwebkit2gtk-4.0-37 2.22.2-0ubuntu0.18.04.1\n\nThis update uses a new upstream release, which includes additional bug\nfixes. After a standard system update you need to restart any applications\nthat use WebKitGTK+, such as Epiphany, to make all the necessary changes. \n\nReferences:\n https://usn.ubuntu.com/usn/usn-3781-1\n CVE-2018-4191, CVE-2018-4197, CVE-2018-4207, CVE-2018-4208,\n CVE-2018-4209, CVE-2018-4210, CVE-2018-4212, CVE-2018-4213,\n CVE-2018-4299, CVE-2018-4306, CVE-2018-4309, CVE-2018-4311,\n CVE-2018-4312, CVE-2018-4314, CVE-2018-4315, CVE-2018-4316,\n CVE-2018-4317, CVE-2018-4318, CVE-2018-4319, CVE-2018-4323,\n CVE-2018-4328, CVE-2018-4358, CVE-2018-4359, CVE-2018-4361\n\nPackage Information:\n https://launchpad.net/ubuntu/+source/webkit2gtk/2.22.2-0ubuntu0.18.04.1\n. \nCVE-2018-4329: Hugo S. \n\nInstallation note:\n\nSafari 12 may be obtained from the Mac App Store. -----------------------------------------------------------------------\nWebKitGTK+ and WPE WebKit Security Advisory WSA-2018-0007\n------------------------------------------------------------------------\n\nDate reported : September 26, 2018\nAdvisory ID : WSA-2018-0007\nWebKitGTK+ Advisory URL : \nhttps://webkitgtk.org/security/WSA-2018-0007.html\nWPE WebKit Advisory URL : \nhttps://wpewebkit.org/security/WSA-2018-0007.html\nCVE identifiers : CVE-2018-4207, CVE-2018-4208, CVE-2018-4209,\n CVE-2018-4210, CVE-2018-4212, CVE-2018-4213,\n CVE-2018-4191, CVE-2018-4197, CVE-2018-4299,\n CVE-2018-4306, CVE-2018-4309, CVE-2018-4311,\n CVE-2018-4312, CVE-2018-4314, CVE-2018-4315,\n CVE-2018-4316, CVE-2018-4317, CVE-2018-4318,\n CVE-2018-4319, CVE-2018-4323, CVE-2018-4328,\n CVE-2018-4358, CVE-2018-4359, CVE-2018-4361. \n\nSeveral vulnerabilities were discovered in WebKitGTK+ and WPE WebKit. \n\nCVE-2018-4207\n Versions affected: WebKitGTK+ before 2.20.0. \n Credit to Google OSS-Fuzz. \n Unexpected interaction causes an ASSERT failure. \n\nCVE-2018-4208\n Versions affected: WebKitGTK+ before 2.20.0. \n Credit to Google OSS-Fuzz. \n Unexpected interaction causes an ASSERT failure. \n\nCVE-2018-4209\n Versions affected: WebKitGTK+ before 2.20.0. \n Credit to Google OSS-Fuzz. \n Unexpected interaction causes an ASSERT failure. \n\nCVE-2018-4210\n Versions affected: WebKitGTK+ before 2.20.0. \n Credit to Google OSS-Fuzz. \n Unexpected interaction with indexing types caused a failure.
