CVE-2009-0843 not yet assigned priority: Debian including 1 source packages (mapserver), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
The msLoadQuery function in mapserv in MapServer 4.x before 4.10.4 and 5.x before 5.2.2 allows remote attackers to determine the existence of arbitrary files via a full pathname in the queryfile parameter, which triggers different error messages depending on whether this pathname exists.
