[GLSA-200512-04] Openswan, IPsec-Tools: Vulnerabilities in ISAKMP Protocol implementation

Vulnerability Assessment Summary
Openswan, IPsec-Tools: Vulnerabilities in ISAKMP Protocol implementation

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200512-04
(Openswan, IPsec-Tools: Vulnerabilities in ISAKMP Protocol implementation)

The Oulu University Secure Programming Group (OUSPG) discovered that
various ISAKMP implementations, including Openswan and racoon (included
in the IPsec-Tools package), behave in an anomalous way when they
receive and handle ISAKMP Phase 1 packets with invalid or abnormal
contents.

Impact

A remote attacker could craft specific packets that would result in a
Denial of Service attack, if Openswan and racoon are used in specific,
weak configurations.

Workaround

There is no known workaround at this time.
