Buffer overflow in the atodn function in strongSwan 2.0.0 through 4.3.4,
when Opportunistic Encryption is enabled and an RSA key is being used,
allows remote attackers to cause a denial of service (pluto IKE daemon
crash) and possibly execute arbitrary code via crafted DNS TXT records.
NOTE: this might be the same vulnerability as CVE-2013-2053 and
Adding to existing GLSA request.
