Source: grads Version: 2.0.a9-2 Severity: normal User: [email protected] Usertags: hardening-format-security hardening
the package grads 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/83137933/buildlog_ubuntu-precise-i386.grads_2.0.a9-2_FAILEDTOBUILD.txt.gz Snippet: gcc -DHAVE_CONFIG_H -I. -I/usr/include/ -I/usr/include/gd -I/usr/include/grib2c -I/usr/include/udunits -I/usr/include/netcdf -I/usr/include/hdf5 -I/usr/include/tiff -I/usr/include/geotiff -I/usr/include/shapelib -I/usr/include/shp -I/usr/include/hdf -D_FORTIFY_SOURCE=2 -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security -Werror=format-security -rdynamic -c gagx.c gagx.c: In function 'gashpwrt': gagx.c:3524:5: error: format not a string literal and no format arguments [-Werror=format-security] gagx.c:3524:5: 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.
