Debian Security Advisory DSA-3866-1 [email protected]
https://www.debian.org/security/ Yves-Alexis Perez

Package : strongswan
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'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.
A fix for a build failure was additionally included in the 5.2.1-6+deb8u4
revision of the strongSwan package.
For the stable distribution (jessie), these problems have been fixed in
version 5.2.1-6+deb8u3.
For the upcoming stable distribution (stretch), these problems have been
fixed in version 5.5.1-4
For the unstable distribution (sid), these problems have been fixed in
version 5.5.1-4.
We recommend that you upgrade your strongswan packages.
