Debian DLA-1522-1 : strongswan security update
High Nessus Plugin ID 117715
SynopsisThe remote Debian host is missing a security update.
DescriptionSze 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.
