    validated sufficiently before attempting signature
    verification, so that invalid input might lead to a
    floating point exception and crash of the process. A
    certificate with an appropriately prepared public key
    sent by a peer could be used for a denial-of-service
    attack.

  - CVE-2017-9023
    ASN.1 CHOICE types are not correctly handled by the
    ASN.1 parser when parsing X.509 certificates with
    extensions that use such types. This could lead to
    infinite looping of the thread parsing a specifically
    crafted certificate.

"Two denial of service vulnerabilities were identified in strongSwan,
an IKE/IPsec suite, using Google's OSS-Fuzz fuzzing project.

CVE-2017-9022

RSA public keys passed to the gmp plugin aren't validated sufficiently
before attempting signature verification, so that invalid input might
lead to a floating point exception and crash of the process. A
certificate with an appropriately prepared public key sent by a peer
could be used for a denial of service attack.

CVE-2017-9023

ASN.1 CHOICE types are not correctly handled by the ASN.1 parser when
parsing X.509 certificates with extensions that use such types. This
could lead to infinite looping of the thread parsing a specifically
crafted certificate.

For Debian 7 'Wheezy', these problems have been fixed in version
4.5.2-1.5+deb7u9.

We recommend that you upgrade your strongswan packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
