    Package        : openswan
    CVE ID         : CVE-2013-2053 CVE-2013-6466
    
    Two vulnerabilities were fixed in Openswan, an IKE/IPsec implementation
    for Linux.
    
    CVE-2013-2053
    
        During an audit of Libreswan (with which Openswan shares some code),
        Florian Weimer found a remote buffer overflow in the atodn()
        function.  This vulnerability can be triggered when Opportunistic
        Encryption (OE) is enabled and an attacker controls the PTR record
        of a peer IP address.
        Authentication is not needed to trigger the vulnerability.
    
    CVE-2013-6466
    
        Iustina Melinte found a vulnerability in Libreswan which also
        applies to the Openswan code. By carefuly crafting IKEv2 packets, an
        attacker can make the pluto daemon derefeences non-received IKEv2
        payload, leading to the daemon crash.
        Authentication is not needed to trigger the vulnerability.
    
    Patches were originally written to fix the vulnerabilities in Libreswan,
    and have been ported to Openswan by Paul Wouters from the Libreswan
    Project.
    
    Since the Openswan package is not maintained anymore in the Debian
    distribution and is not available in testing and unstable suites, it is
    recommended for IKE/IPsec users to switch to a supported implementation
    like strongSwan.
    
    For the oldstable distribution (squeeze), these problems have been fixed in
    version 2.6.28+dfsg-5+squeeze2.
    
    For the stable distribution (wheezy), these problems have been fixed in
    version 2.6.37-3.1.
    
    We recommend that you upgrade your openswan packages.
