Gnome » Epiphany : Security Vulnerabilities, CVEs, CVSS score >= 7

In Epiphany (aka GNOME Web) through 43.0, untrusted web content can trick users into exfiltrating passwords, because autofill occurs in sandboxed contexts.

In GNOME Epiphany before 41.4 and 42.x before 42.2, an HTML document can trigger a client buffer overflow (in ephy_string_shorten in the UI process) via a long page title. The issue occurs because the number of bytes for a UTF-8 ellipsis character is not properly considered.

WebKitGTK and WPE WebKit prior to version 2.24.1 are vulnerable to address bar spoofing upon certain JavaScript redirections. An attacker could cause malicious web content to be displayed as if for a trusted URI. This is similar to the CVE-2018-8383 issue in Microsoft Edge.

libephymain.so in GNOME Web (aka Epiphany) through 3.28.2.1 allows remote attackers to cause a denial of service (application crash) via certain window.open and document.write calls.

ephy-session.c in libephymain.so in GNOME Web (aka Epiphany) through 3.28.2.1 allows remote attackers to cause a denial of service (application crash) via JavaScript code that triggers access to a NULL URL, as demonstrated by a crafted window.open call.

GNOME Web (Epiphany) 3.23 before 3.23.5, 3.22 before 3.22.6, 3.20 before 3.20.7, 3.18 before 3.18.11, and prior versions, is vulnerable to a password manager sweep attack resulting in the remote exfiltration of stored passwords for a selected set of websites.
