Source: ggobi Version: 2.1.10-3 Severity: normal User: [email protected] Usertags: hardening-format-security hardening
the package ggobi 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/83134069/buildlog_ubuntu-precise-i386.ggobi_2.1.10-3_FAILEDTOBUILD.txt.gz Snippet: libtool: compile: gcc -DHAVE_CONFIG_H -I. -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 -I/usr/include/libxml2 -D_FORTIFY_SOURCE=2 -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security -Werror=format-security -MT ggobi.lo -MD -MP -MF .deps/ggobi.Tpo -c ggobi.c -fPIC -DPIC -o .libs/ggobi.o ggobi.c: In function 'ValidateGGobiRef': ggobi.c:701:5: error: format not a string literal and no format arguments [-Werror=format-security] ggobi.c:704:5: error: format not a string literal and no format arguments [-Werror=format-security] ggobi.c: In function 'ValidateDatadRef': ggobi.c:721:5: error: format not a string literal and no format arguments [-Werror=format-security] ggobi.c:723:5: error: format not a string literal and no format arguments [-Werror=format-security] ggobi.c: In function 'ValidateDisplayRef': ggobi.c:742:5: error: format not a string literal and no format arguments [-Werror=format-security] ggobi.c:744:5: 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.
