Binary package hint: amavisd-milter
In maverick and and earlier, amavisd-new-milter was built with the PIE
and BINDNOW hardening options (see
https://wiki.ubuntu.com/Security/HardeningWrapper and
http://wiki.debian.org/Hardening). With the replacement of amavisd-new-
milter by amavisd-milter, this hardening protection is gone.
To reproduce:
1) grab the hardening_check script from http://bazaar.launchpad.net/~ubuntu-bugcontrol/qa-regression-testing/master/view/head:/scripts/built-binaries/hardening-check
2) unpack via dpkg-deb -x or install amavsid-milter
3) run the hardening-check script on (EXTRACTEDPATH)/usr/sbin/amavisd-milter
4) output should look like:
/usr/sbin/amavisd-milter:
Position Independent Executable: yes
Stack protected: yes
Fortify Source functions: yes
Read-only relocations: yes
Immediate binding: yes
however, without hardening-wrapper applied, it looks like:
/usr/sbin/amavisd-milter:
Position Independent Executable: no, normal executable!
Stack protected: yes
Fortify Source functions: yes
Read-only relocations: yes
Immediate binding: no, not found!
