More information:

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.
