CVE-2016-9433: An issue was discovered in the Tatsuya Kinoshita w3m fork before 0.5.3-31.

Security readout for executives and security teams

CVE-2016-9433 is a denial-of-service flaw in the Tatsuya Kinoshita w3m fork before 0.5.3-31. A malicious HTML page could crash or disrupt w3m through out-of-bounds array access. Available sources indicate availability risk, not data theft or code execution. Exposure is most likely where vulnerable w3m versions render untrusted HTML. This includes user browsing, terminal-based workflows, and automated jobs that fetch or convert HTML using w3m. Confirm actual package lineage and version because the source bundle lists affected vendor and product metadata as unavailable. Prioritize remediation where w3m processes internet-sourced HTML or supports business automation. This is not currently evidenced as a critical compromise risk, but vulnerable deployments can be disrupted remotely and should be updated during normal security maintenance. Mitigation focus: Upgrade w3m to 0.5.3-31 or later where available.; Apply distribution security updates, including relevant Gentoo GLSA guidance.; Avoid rendering untrusted HTML with vulnerable w3m builds..
