CVE-2016-9626: An issue was discovered in the Tatsuya Kinoshita w3m fork before 0.5.3-33.

Security readout for executives and security teams

CVE-2016-9626 is a denial-of-service issue in the Tatsuya Kinoshita w3m fork before 0.5.3-33. A crafted HTML page can trigger infinite recursion and crash or hang w3m. The available sources do not indicate data theft, code execution, or confirmed active exploitation. Exposure is most likely on Unix/Linux systems using w3m interactively or in scripts to render or process untrusted HTML. Business impact depends on whether w3m is in critical automation, monitoring, mail handling, or server-side content processing workflows. Handle during normal vulnerability remediation unless w3m processes untrusted HTML in business-critical automation. Prioritize faster if affected systems can be remotely fed HTML and process availability matters. Mitigation focus: Identify all systems and workflows using w3m.; Upgrade w3m to 0.5.3-33 or a vendor-backported fixed package.; Check distribution security advisories for exact package names and fixed builds..
