Source: leafpad Version: 0.8.18.1-1 Severity: normal User: [email protected] Usertags: hardening-format-security hardening
the package leafpad fails to compile with the new hardened compiler flags dpkg-buildflag outputs [0]. The problematic flag is: -Werror=format-security See the ubuntu buildlog: https://launchpadlibrarian.net/83144457/buildlog_ubuntu-precise-i386.leafpad_0.8.18.1-1_FAILEDTOBUILD.txt.gz Snippet: gcc -DHAVE_CONFIG_H -I. -I.. -DICONDIR=\"/usr/share/pixmaps\" -D_FORTIFY_SOURCE=2 -pthread -I/usr/include/gtk-2.0 -I/usr/lib/x86_64-linux-gnu/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/pango-1.0 -I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/libpng12 -I/usr/include/cairo -I/usr/include/gio-unix-2.0/ -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security -Werror=format-security -Wall -c -o leafpad-dialog.o `test -f 'dialog.c' || echo './'`dialog.c dialog.c: In function 'run_dialog_message': dialog.c:39:3: error: format not a string literal and no format arguments [-Werror=format-security] dialog.c: In function 'create_dialog_message_question': dialog.c:64:3: error: format not a string literal and no format arguments [-Werror=format-security] cc1: some warnings being treated as errors The buildflags are not exported in debian, but can be enabled e.g. by adding this to debian/rules: DPKG_EXPORT_BUILDFLAGS = 1 include /usr/share/dpkg/buildflags.mk Please fix the issues and maybe also enable the hardened build in debian.
