Upgrade Debian:unstable w3m to version 0.5.3-30 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream w3m package and not the w3m package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
An issue was discovered in the Tatsuya Kinoshita w3m fork before 0.5.3-31. w3m doesn't properly validate the value of tag attribute, which allows remote attackers to cause a denial of service (heap buffer overflow crash) and possibly execute arbitrary code via a crafted HTML page.
