Package: debhelper Version: 10.10.9 Severity: normal Since shell escaping the dpkg-maintscript-helper arguments can produce invalid parameters, dh_installdeb should check whether the version and package arguments (if given) are valid for a package name or version. E.g. \$VARIABLE (after unescaping: $VARIABLE) cannot be a valid package name or '1.2-3\~4' (after unescaping: 1.2-3\~4) cannot be a valid version.
There is #880430 requesting a lintian check, but it would probably be better not to generate known broken packages. This brokenness may not be detected immediately, but only on special upgrade paths. (The lintian bug has references to an occurrence in the package name (needed a special upgrade path to show up) and another one in the version). Andreas
