CVE-2016-9441: An issue was discovered in the Tatsuya Kinoshita w3m fork before 0.5.3-31.

Security readout for executives and security teams

CVE-2016-9441 is a crash bug in the Tatsuya Kinoshita fork of w3m before 0.5.3-31. A malicious HTML page can make w3m segfault, causing denial of service for that session or workflow. Sources do not show code execution or active exploitation. Exposure is most likely where w3m is installed and used to open untrusted HTML, including terminal users, scripts, mail/news workflows, or automated fetch-and-render jobs. The provided affected-product metadata is incomplete, so validate against installed package names and distributor advisories. Prioritize remediation where w3m is used in business automation or exposed content-handling paths. For ordinary ad hoc terminal browsing, urgency is lower, but patching is still appropriate because malicious content can interrupt workflows. Mitigation focus: Upgrade w3m to a vendor build that includes the 0.5.3-31 fix or later.; Check your Linux distribution advisory for the exact patched package version.; Limit w3m use against untrusted HTML until patched..
