CVE-2016-9432: An issue was discovered in the Tatsuya Kinoshita w3m fork before 0.5.3-31.

Security readout for executives and security teams

CVE-2016-9432 is a denial-of-service flaw in the Tatsuya Kinoshita w3m fork before 0.5.3-31. A malicious HTML page can corrupt memory and crash the browser. Business impact is service interruption where w3m is used interactively or in automated HTML-processing workflows. Exposure is most likely on Linux or Unix systems that run the affected w3m fork and open untrusted HTML. Risk increases if scripts, mail tooling, monitoring, or batch jobs use w3m to process remote web content. General public-facing server exposure is not established by the provided sources. Prioritize remediation where w3m is used in automated workflows or on shared systems, because a crafted page could crash business processes. This is not documented as actively exploited and has no CVSS in the bundle, so urgency is moderate unless local dependency is high. Mitigation focus: Inventory endpoints and servers with w3m installed or invoked by automation.; Update w3m to 0.5.3-31 or later where that vendor version applies.; Follow distribution vendor advisories, including Gentoo GLSA-201701-08, for package-specific fixes..
