CVE-2013-2053 Openswan: remote buffer overflow in atodn()
A buffer overflow flaw was found in Openswan. If Opportunistic
Encryption
were enabled (“oe=yes” in “/etc/ipsec.conf”) and an RSA key configured,
an
attacker able to cause a system to perform a DNS lookup for an
attacker-
controlled domain containing malicious records (such as by sending an
email that triggers a DKIM or SPF DNS record lookup) could cause
Openswan’s pluto IKE daemon to crash or, potentially, execute
arbitrary
code with root privileges. With “oe=yes” but no RSA key configured,
the
issue can only be triggered by attackers on the local network who can
control the reverse DNS entry of the target system. Opportunistic
Encryption is disabled by default. (CVE-2013-2053)
