CVE-2010-3312: Gnome Epiphany

Medium severity, CVSS 5.8. EPSS: 1% chance of exploitation in the next 30 days.

Epiphany 2.28 and 2.29, when WebKit and LibSoup are used, unconditionally displays a closed-lock icon for any URL beginning with the https: substring, without any warning to the user, which allows man-in-the-middle attackers to spoof arbitrary https web sites via a crafted X.509 server certificate.

Affected products

• Gnome Epiphany: version 2.28 only; version 2.29 only
