Secure testing team - Jan 2010 - Bug#566326: xulrunner-1.9: iceweasel "clear private data" leaves traces on disk due to linkage to system libsqlite3 instead of embedded copy

Package: xulrunner-1.9
Version: 1.9.0.16-1
Severity: important
Tags: security

The symptom:
 Run iceweasel.
 Visit some web pages.
 Tools / Clear Private Data
 cd .mozilla/firefox/*.default
 grep visited_hostname *.sqlite
 Result: places.sqlite and sometimes others

 There, one sees that the data that is supposed to be cleared is
 actually still on disk, until one does:
 for f in *.sqlitel; do sqlite3 "${f}" VACUUM; done
 (or it is overwritten by new data)

In https://bugzilla.mozilla.org/show_bug.cgi?id=385834#c33, it says
this should not happen because sqlite3 is compiled with
-DSQLITE_SECURE_DELETE, which causes deletes to overwrite old data
with zeros. Indeed, in db/sqlite3/src/Makefile.in:

DEFINES = \
  -DSQLITE_SECURE_DELETE=1 \

But that sqlite3 is not used, the one from package libsqlite3-0 is
used, and this one is *not* compiled with -DSQLITE_SECURE_DELETE!

Glancing at https://buildd.debian.org/build.php, this seems to be
solved in unstable by having libsqlite3-0 be compiled with
-DSQLITE_SECURE_DELETE, but IMHO we still need to solve that security
leak in stable.
