Package: last-align Version: 198-1 Severity: important Tags: patch Dear Maintainer,
The hardening flags are missing because the build system ignores them. The attached patch fixes the issue, if possible it should be sent to upstream. To check if all flags were correctly enabled you can use `hardening-check` from the hardening-includes package and check the build log (hardening-check doesn't catch everything): $ hardening-check /usr/bin/lastdb /usr/bin/lastal /usr/bin/lastdb: Position Independent Executable: no, normal executable! Stack protected: yes Fortify Source functions: no, only unprotected functions found! Read-only relocations: yes Immediate binding: no not found! /usr/bin/lastal: Position Independent Executable: no, normal executable! Stack protected: yes Fortify Source functions: yes (some protected functions found) Read-only relocations: yes Immediate binding: no not found! (Position Independent Executable and Immediate binding is not enabled by default.) Use find -type f \( -executable -o -name \*.so\* \) -exec hardening-check {} + on the build result to check all files.
