CVE-2018-0739 (OpenSSL advisory) [Moderate severity] 27 March 2018:
Constructed ASN.1 types with a recursive definition (such as can be
found in PKCS7) could eventually exceed the stack given malicious
input with excessive recursion. This could result in a Denial Of
Service attack. There are no such structures used within SSL/TLS
that come from untrusted sources so this is considered safe.
Reported by OSS-fuzz.
This patch also entirely removes support for SSLv3. The patch to
disable it didn't apply and since nobody has been using this before,
we will not compile it into OpenSSL any more.

Core 119 update delivers an updated PAM whereby the libdir has been changed from /lib to /usr/lib
but the old libraries and symlinks are still presant. Since the system searches /lib before
/usr/lib , the old libs and symlinks are used which ends up in an `LIBPAM_EXTENSION_1.1' not found.

We will swap the key that we use to sign Pakfire packages
since the current one is considered outdated cryptography.

As suggested by Oliver "giller" Fieker <oli@new-lan.de>
in bug 10592 I added the functionality to use the squid as ram-only cache.
Further it defines the maximum_object_size_in_memory
as 2% of the in the webif defined "Memory cache size".
The maximum_object_size_in_memory should have a useful
size of the defined memory cache and I don't want to
create another variable which muste be fulled in by the user.

DNSSEC-validating nameservers return an "ad" (Authenticated Data)
flag in the DNS response header. This can be used as a negative
indicator for DNSSEC validation: In case a nameserver does not
return the flag, but failes to look up a domain with an invalid
signature, it does not support DNSSEC validation.
This makes it easier to detect nameservers which do not fully
comply to the RFCs or try to tamper DNS queries.
See bug #11595 (https://bugzilla.ipfire.org/show_bug.cgi?id=11595) for further details.
The second version of this patch avoids unnecessary usage of
grep. Thanks to Michael Tremer for the hint.

This will work fine for FF 27 or newer, Chrome 30 or newer,
IE 11 on Windows 7 or newer, Opera 17 or newer, Safari 9 or
newer, Android 5.0 or newer and Java 8 or newer
Since IPFire is not supposed to host any other applications and
all have been removed in the last few Core Updates, only the web
user interface is served over HTTPS here. We clearly prefer
security over compatibility.

Change the TLS cipher list of Apache to "Mozilla Modern".
ECDSA is preferred over RSA to save CPU time on both server
and client. Clients without support for TLS 1.2 and AES will
experience connection failures.

This seems to be a failed concept and causes issues with transferring
large packets through an IPsec tunnel connection.
This configures the kernel to still respond to PMTU ICMP discovery
messages, but will not try this on its own.
