Security readout for executives and security teams

CVE-2016-9429 is a buffer overflow in the Tatsuya Kinoshita w3m fork before 0.5.3-31. A crafted HTML page could crash w3m and may allow arbitrary code execution. Treat this as important where w3m handles untrusted web or HTML content. Exposure is limited to environments running the Tatsuya Kinoshita w3m fork before 0.5.3-31. Risk is highest where that binary is used to process HTML from external or untrusted sources. Prioritize remediation for internet-facing or automation-heavy systems that use w3m on untrusted content. The business concern is service disruption and possible code execution, but evidence in this bundle does not show active exploitation. Mitigation focus: Inventory systems for the affected w3m fork and installed version.; Upgrade to a vendor-supported package at or beyond the fixed version line.; Follow distribution guidance, including Gentoo GLSA-201701-08 where applicable..
