Package: gtk2-engines-oxygen Version: 1.2.2-1 Severity: normal Tags: patch Dear Maintainer,
The LDFLAGS hardening flags are missing because they are overwritten in debian/rules. For more hardening information please have a look at [1], [2] and [3]. The following patch fixes the issue. diff -Nru gtk2-engines-oxygen-1.2.2/debian/rules gtk2-engines-oxygen-1.2.2/debian/rules --- gtk2-engines-oxygen-1.2.2/debian/rules 2012-01-21 20:09:29.000000000 +0100 +++ gtk2-engines-oxygen-1.2.2/debian/rules 2012-04-15 18:54:39.000000000 +0200 @@ -7,9 +7,9 @@ dh_auto_configure -- \ -DDEBIAN_NO_DEMOS=1 \ -DCMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT=yes \ - -DCMAKE_SHARED_LINKER_FLAGS="-Wl,--no-undefined -Wl,--as-needed" \ - -DCMAKE_MODULE_LINKER_FLAGS="-Wl,--no-undefined -Wl,--as-needed" \ - -DCMAKE_EXE_LINKER_FLAGS="-Wl,--no-undefined -Wl,--as-needed" + -DCMAKE_SHARED_LINKER_FLAGS="$(LDFLAGS) -Wl,--no-undefined -Wl,--as-needed" \ + -DCMAKE_MODULE_LINKER_FLAGS="$(LDFLAGS) -Wl,--no-undefined -Wl,--as-needed" \ + -DCMAKE_EXE_LINKER_FLAGS="$(LDFLAGS) -Wl,--no-undefined -Wl,--as-needed" override_dh_makeshlibs: dh_makeshlibs -X/usr/lib/$(DEB_HOST_MULTIARCH)/gtk-2.0 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/lib/x86_64-linux-gnu/gtk-2.0/2.10.0/engines/liboxygen-gtk.so /usr/lib/x86_64-linux-gnu/gtk-2.0/2.10.0/engines/liboxygen-gtk.so: Position Independent Executable: no, regular shared library (ignored) Stack protected: yes Fortify Source functions: no, only unprotected functions found!
