CVE-2016-9425: An issue was discovered in the Tatsuya Kinoshita w3m fork before 0.5.3-31.

Security readout for executives and security teams

CVE-2016-9425 affects the w3m text-based web browser fork maintained by Tatsuya Kinoshita before version 0.5.3-31. A malicious HTML page could crash the browser and may allow code execution. This mainly matters where w3m opens untrusted web content, email-rendered HTML, or automated HTML retrieval output. Exposure is likely limited to systems with vulnerable w3m installed and used to process attacker-controlled HTML. Workstations, terminal workflows, mail helpers, and automation that render external HTML through w3m are the main areas to check. Prioritize remediation where w3m processes untrusted HTML, especially in automation or shared environments. Business urgency is lower if w3m is absent or only used manually with trusted local content. Mitigation focus: Upgrade w3m to 0.5.3-31 or a vendor-fixed later package.; Check Gentoo or operating-system vendor advisories for packaged fix details.; Avoid processing untrusted HTML with vulnerable w3m until remediated..
