Drop sqlite3, nss and nspr backports from our APT repository
bugfix/use-our-own-sqlite we have imported
sqlite3 backports into our APT repository, as:
- our current browser (24.2.0esr-0+tails3~bpo60+1) depends on these packages;
- these packages were dropped from mozilla.debian.net's squeeze-backports repository.
This workaround will (hopefully) be useless once we rebase the browser on Iceweasel 24.2.0esr-1.
Dropping these packages will make us install an old, unsafe version of NSS. We should therefore check that Iceweasel does not use the system one:
- xulrunner 24.2.0esr-1 ships
/usr/lib/xulrunner-24.0/libnss3.so, which the -0 one does not
- xulrunner 24.2.0esr-1's
ldd /usr/lib/xulrunner-24.0/libxul.sosays it is linked on the system
/usr/lib/libnss3.so, but it says
/usr/lib/xulrunner-24.0/libxul.so: /usr/lib/libsmime3.so: version `NSS_3.15' not found (required by /usr/lib/xulrunner-24.0/libxul.so); does this mean it won't / can't use the system NSS?
- On Tails 0.22,
lsof | grep nss | grep icewsays it has loaded
/usr/lib/libnss3.soand various libs from
/usr/lib/nss/; while with 24.2.0esr-1, it has loaded
/usr/lib/xulrunner-24.0/libnss*.so, so we should be safe.
Still, other apps will be using an old, unsafe NSS. Only Pidgin depends on this package. We should probably upload a fixed version to squeeze-backports: #6497.
