Yes, those warnings concern me too. The build uses -O2 &
-D_FORTIFY_SOURCE=2, but running hardening-check --verbose on each of
the libraries shows this:
/usr/lib/x86_64-linux-gnu/liblastfm.so.0.4.0:
Position Independent Executable: no, regular shared library (ignored)
Stack protected: yes
Fortify Source functions: no, only unprotected functions found!
unprotected: strncpy
unprotected: fread
Read-only relocations: yes
Immediate binding: no, not found!
/usr/lib/x86_64-linux-gnu/liblastfm_fingerprint.so.0.4.0:
Position Independent Executable: no, regular shared library (ignored)
Stack protected: yes
Fortify Source functions: no, only unprotected functions found!
unprotected: memset
unprotected: memmove
unprotected: memcpy
Read-only relocations: yes
Immediate binding: no, not found!
I don't know which of these--if any--are false positives. Any help
would be appreciated.
