Security readout for executives and security teams

This flaw affects old MapServer mapserv versions. A long id value in a query request could trigger a buffer overflow because the program did not reliably terminate the string. For organizations still running these versions, the risk is mainly public-facing legacy GIS services. Exposure is most likely where legacy MapServer mapserv CGI or equivalent public routes still run MapServer 4.x before 4.10.4 or 5.x before 5.2.2. The provided data has no CPE inventory, so product mapping must be confirmed locally. Prioritize remediation for internet-facing MapServer services, especially old GIS applications that may have escaped normal patch cycles. The issue is old, but remotely reachable buffer overflows in unsupported software remain material operational risk. Mitigation focus: Upgrade MapServer 4.x to 4.10.4 or later, or 5.x to 5.2.2 or later.; Apply relevant downstream operating-system package updates where MapServer was installed through a distribution.; Restrict external access to legacy mapserv endpoints until upgrade status is confirmed..
