Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3074 advisory.

- XSS can occur in GNOME Web (aka Epiphany) before 40.4 and 41.x before 41.1 via an about: page, as demonstrated by ephy-about:overview when a user visits an XSS payload page often enough to place that page on the Most Visited list. (CVE-2021-45085)

- XSS can occur in GNOME Web (aka Epiphany) before 40.4 and 41.x before 41.1 when View Source mode or Reader mode is used, as demonstrated by a a page title. (CVE-2021-45087)

- XSS can occur in GNOME Web (aka Epiphany) before 40.4 and 41.x before 41.1 via an error page.
(CVE-2021-45088)

- 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. (CVE-2022-29536)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the epiphany-browser packages.

For Debian 10 buster, these problems have been fixed in version 3.32.1.2-3~deb10u2.
