Package: dact Version: 0.8.42-3 Severity: important Tags: patch Dear Maintainer,
The CPPFLAGS hardening flags are missing because they are not set
in debian/rules.
The following patch fixes the issue.

To check if all flags were correctly enabled you can use
`hardening-check` from the hardening-includes package and check
the build log (hardening-check doesn't catch everything):
$ hardening-check /usr/bin/dact /usr/lib/dact/libdact.so
/usr/bin/dact:
Position Independent Executable: no, normal executable!
Stack protected: yes
Fortify Source functions: yes (some protected functions found)
Read-only relocations: yes
Immediate binding: no not found!
/usr/lib/dact/libdact.so:
Position Independent Executable: no, regular shared library (ignored)
Stack protected: yes
Fortify Source functions: yes (some protected functions found)
Read-only relocations: yes
Immediate binding: no not found!
(Position Independent Executable and Immediate binding is not
enabled by default.)
Use find -type f \( -executable -o -name \*.so\* \) -exec
hardening-check {} + on the build result to check all files.

Simon
