For Debian 10 buster, this problem has been fixed in version 0.5.3-37+deb10u1.

We recommend that you upgrade your w3m packages.

For the detailed security status of w3m please refer to its security tracker page at: [link moved to references]

Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
