- Updated to strongSwan 5.3.5 providing the following changes:
*Fixed a DoS vulnerability in the gmp plugin that was caused by insufficient input
validation when verifying RSA signatures. More specifically, mpz_powm_sec() has two
requirements regarding the passed exponent and modulus that the plugin did not
enforce, if these are not met the calculation will result in a floating point exception
that crashes the whole process.
This vulnerability has been registered as CVE-2017-9022.
Please refer to our blog for details.
*Fixed a DoS vulnerability in the x509 plugin that was caused because the ASN.1 parser
didn't handle ASN.1 CHOICE types properly, which could result in an infinite loop when
parsing X.509 extensions that use such types.
This vulnerability has been registered as CVE-2017-9023.
Please refer to our blog for details.
*The behavior during IKEv2 CHILD_SA rekeying has been changed in order to avoid
traffic loss. When responding to a CREATE_CHILD_SA request to rekey a CHILD_SA
the responder already has everything available to install and use the new CHILD_SA.
However, this could lead to lost traffic as the initiator won't be able to process
inbound packets until it processed the CREATE_CHILD_SA response and updated the
inbound SA. To avoid this the responder now only installs the new inbound SA and
delays installing the outbound SA until it receives the DELETE for the replaced CHILD_SA.
*The messages transporting these DELETEs could reach the peer before packets sent
with the deleted outbound SAs reach it. To reduce the chance of traffic loss due
to this the inbound SA of the replaced CHILD_SA is not removed for a configurable
amount of seconds (charon.delete_rekeyed_delay) after the DELETE has been processed.
*The code base has been ported to Apple's ARM64 iOS platform, which required several
changes regarding the use of variadic functions. This was necessary because the calling
conventions for variadic and regular functions are different there.
This means that assigning a non-variadic function to a variadic function pointer, as we
did with our enumerator_t::enumerate() implementations and several callbacks, will
result in crashes as the called function accesses the arguments differently than the

Changes in version 5.2.2:
* Fixed a denial-of-service vulnerability triggered by an IKEv2 Key Exchange
payload that contains the Diffie-Hellman group 1025. This identifier was
used internally for DH groups with custom generator and prime. Because
these arguments are missing when creating DH objects based on the KE
payload an invalid pointer dereference occurred. This allowed an attacker
to crash the IKE daemon with a single IKE_SA_INIT message containing such
a KE payload. The vulnerability has been registered as CVE-2014-9221.
* The left/rightid options in ipsec.conf, or any other identity in
strongSwan, now accept prefixes to enforce an explicit type, such as
email: or fqdn:. Note that no conversion is done for the remaining string,
refer to ipsec.conf(5) for details.
* The post-quantum Bimodal Lattice Signature Scheme (BLISS) can be used as
an IKEv2 public key authentication method. The pki tool offers full
support for the generation of BLISS key pairs and certificates.
* Fixed mapping of integrity algorithms negotiated for AH via IKEv1.
This could cause interoperability issues when connecting to older versions
of charon.
Changes in version 5.2.1:
* The new charon-systemd IKE daemon implements an IKE daemon tailored for
use with systemd. It avoids the dependency on ipsec starter and uses
swanctl as configuration backend, building a simple and lightweight
solution. It supports native systemd journal logging.
* Support for IKEv2 fragmentation as per RFC 7383 has been added. Like IKEv1
fragmentation it can be enabled by setting fragmentation=yes in ipsec.conf.
* Support of the TCG TNC IF-M Attribute Segmentation specification proposal.
All attributes can be segmented. Additionally TCG/SWID Tag, TCG/SWID Tag ID
and IETF/Installed Packages attributes can be processed incrementally on a
per segment basis.

and a _fipscheck script to verify binaries/libraries/plugings
shipped in the strongswan-hmac package.
With enabled fips in the kernel, the ipsec script will call it
before any action or in a enforced/manual "ipsec _fipscheck" call.
Added config file to load openssl and kernel af-alg plugins, but
not all the other modules which provide further/alternative algs.
Applied a filter disallowing non-approved algorithms in fips mode.
(fate#316931,bnc#856322).
[+ strongswan_fipscheck.patch, strongswan_fipsfilter.patch]
- Fixed file list in the optional (disabled) strongswan-test package.
- Fixed build of the strongswan built-in integrity checksum library
and enabled building it only on architectures tested to work.
- Fix to use bug number 897048 instead 856322 in last changes entry.
- Applied an upstream patch reverting to store algorithms in the
registration order again as ordering them by identifier caused
weaker algorithms to be proposed first by default (bsc#897512).
