reopen 674537 thanks Dear Maintainer,
The LDFLAGS hardening flags are still missing because they are
not set in debian/rules. For more hardening information please
have a look at [1], [2] and [3].
The following patch fixes the issue.
diff -Nru aria2-1.15.0/debian/rules aria2-1.15.0/debian/rules

- LDFLAGS="-Wl,-z,defs,--as-needed" \
+ LDFLAGS="$(LDFLAGS) -Wl,-z,defs,--as-needed" \
--prefix=/usr \
--with-gnutls \
--without-openssl \
To check if all flags were correctly enabled you can use
`hardening-check` from the hardening-includes package and check
the build log (for example with blhc [4]) (hardening-check
doesn't catch everything):
$ hardening-check /usr/bin/aria2c
/usr/bin/aria2c:
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.
Regards,
Simon
