Description

The remote host is affected by the vulnerability described in GLSA-202405-27 (Epiphany: Buffer Overflow)

 - 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 this issue but has instead relied only on the application's self-reported version number.

Solution

All Epiphany users should upgrade to the latest version:

 # emerge --sync # emerge --ask --oneshot --verbose >=www-client/epiphany-42.4
