Package : strongswan
Version : 4.5.2-1.5+deb7u9
CVE ID : CVE-2017-9022 CVE-2017-9023

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&#x27;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.
