The remote Red Hat host is missing a security update.
An updated ipsec-tools package that fixes a bug in parsing of ISAKMP
headers is now available.
This update has been rated as having moderate security impact by the
Red Hat Security Response Team.
The ipsec-tools package is used in conjunction with the IPsec
functionality in the linux kernel. The ipsec-tools package includes :
- setkey, a program to directly manipulate policies and
SAs - racoon, an IKEv1 keying daemon
A bug was found in the way the racoon daemon handled incoming ISAKMP
requests. It is possible that an attacker could crash the racoon
daemon by sending a specially crafted ISAKMP packet. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
name CVE-2005-0398 to this issue.
Additionally, the following issues have been fixed: - racoon
mishandled restarts in the presence of stale administration sockets. -
on Red Hat Enterprise Linux 4, racoon and setkey did not properly set
up forward policies, which prevented tunnels from working.
Users of ipsec-tools should upgrade to this updated package, which
contains backported patches, and is not vulnerable to these issues.
