Medium Nessus Plugin ID 14482
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200404-17 (ipsec-tools and iputils contain a remote DoS vulnerability)
When racoon receives an ISAKMP header, it allocates memory based on the length of the header field. Thus, an attacker may be able to cause a Denial of Services by creating a header that is large enough to consume all available system resources.
This vulnerability may allow an attacker to remotely cause a Denial of Service.
