Debian DLA-1522-1 : strongswan security update

High Nessus Plugin ID 117715


The remote Debian host is missing a security update.


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.


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


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.


Upgrade the affected packages.
