Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 10 host has packages installed that are affected by a vulnerability as referenced in the dsa-4953 advisory.

Thorsten Glaser and Axel Beckert reported that lynx, a non-graphical (text-mode) web browser, does not properly handle the userinfo subcomponent of a URI, which can lead to leaking of credential in cleartext in SNI data. For the stable distribution (buster), this problem has been fixed in version 2.8.9rel.1-3+deb10u1. We recommend that you upgrade your lynx packages. For the detailed security status of lynx please refer to its security tracker page at: https://security-tracker.debian.org/tracker/lynx

Tenable has extracted the preceding description block directly from the Debian security advisory.

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

Solution

Upgrade the lynx packages.

For the stable distribution (buster), this problem has been fixed in version 2.8.9rel.1-3+deb10u1.
