Debian DLA-1522-1 : strongswan security update

Medium Nessus Plugin ID 117715

Synopsis

The remote Debian host is missing a security update.

Description

Sze Yiu Chau and his team from Purdue University and The University of
Iowa found several security issues in the gmp plugin for strongSwan,
an IKE/IPsec suite.

CVE-2018-16151

The OID parser in the ASN.1 code in gmp allows any number of random
bytes after a valid OID.

CVE-2018-16152

The algorithmIdentifier parser in the ASN.1 code in gmp doesn't
enforce a NULL value for the optional parameter which is not used with
any PKCS#1 algorithm.

For Debian 8 'Jessie', these problems have been fixed in version
5.2.1-6+deb8u7.

We recommend that you upgrade your strongswan packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.

Solution

Upgrade the affected packages.
