Package: skanlite Version: 0.8-2 Severity: normal Tags: patch Dear Maintainer,
The LDFLAGS hardening flags are missing because they are
overwritten in debian/rules.
DEB_*_MAINT_APPEND is the preferred way to set additional flags
(see man dpkg-buildflags for more information). For more
hardening information please have a look at [1], [2] and [3].
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 (for example with blhc [4]) (hardening-check
doesn't catch everything):
$ hardening-check /usr/bin/skanlite
/usr/bin/skanlite:
Position Independent Executable: no, normal executable!
Stack protected: no, not found!
Fortify Source functions: unknown, no protectable libc functions used
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.
Regards,
Simon
