Description:
Updated openswan packages fix security vulnerability:
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).
