DESCRIPTION:
Multiple vulnerabilities have been reported in Openswan, which can be
exploited by malicious people to compromise a user's system.

1) A boundary error when processing the "cisco_dns_info" and
"cisco_domain_info" fields can be exploited to cause a buffer
overflow via a specially crafted packet with DNS payload.

2) A boundary error when processing the "cisco_banner" or
"server_banner" fields can be exploited to cause a buffer overflow
via a string longer than 500 characters.

NOTE: This vulnerability was introduced in version 2.6.26.

3) An input sanitation error when processing the "cisco_dns_info",
"cisco_domain_info", "cisco_banner", and "server_banner" fields can
be exploited to inject arbitrary shell commands via a specially
crafted string.

Successful exploitation of these vulnerabilities may allow execution
of arbitrary code but requires tricking a user into connecting to a
malicious Cisco compatible gateway using Extended Authentication
(XAUTH).

The vulnerabilities are reported in version 2.6.25 through 2.6.28.

SOLUTION:
Apply patches or update to version 2.6.29
