Source: microdc2 Version: 0.15.6-2 Severity: normal User: [email protected] Usertags: hardening-format-security hardening
the package microdc2 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/83073784/buildlog_ubuntu-precise-i386.microdc2_0.15.6-2_FAILEDTOBUILD.txt.gz Snippet: gcc -DHAVE_CONFIG_H -I. -I.. -I../lib -I../lib -D_FORTIFY_SOURCE=2 -Wall -I/usr/include/libxml2 -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security -Werror=format-security -c screen.c screen.c: In function 'flag_vputf': screen.c:249:9: 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.
