Debian LTS Advisory DLA-2736-1 [email protected]

Package : lynx
Version : 2.8.9dev11-1+deb9u1
CVE ID : CVE-2021-38165
Debian Bug : #991971

It was discovered that there was a remote authentication credential
leak in the "lynx" text-based web browser.

The package now correctly handles authentication subcomponents in
URIs (eg. https://user:[email protected]) to avoid remote attackers
discovering cleartext credentials in SSL connection data.

For Debian 9 "Stretch", this problem has been fixed in version
2.8.9dev11-1+deb9u1.

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

these updates to your system and frequently asked questions can be
