    Package        : mapserver
    Version        : 7.6.2-1+deb11u1
    CVE ID         : CVE-2021-32062 CVE-2025-59431
    Debian Bug     : 988208

    Vulnerabilities were found in mapserver, a CGI-based framework for
    Internet map services, which could lead to security controls bypass or
    SQL injection.

    CVE-2021-32062

        Due to a logic flaw associated with processing map parameter, it is
        possible to specify an arbitrary mapfile that bypasses the
        `MS_MAP_NO_PATH` and `MS_MAP_PATTERN` security control checks.

    CVE-2025-59431

        Alwin Warringa discovered that XML Filter Query directive
        `PropertyName` is vulnerably to Boolean-based SQL injection,
        allowing to manipulate backend database queries via crafted XML
        Filter Query directives.

    For Debian 11 bullseye, these problems have been fixed in version
    7.6.2-1+deb11u1.

    We recommend that you upgrade your mapserver packages.
