Red Hat Security Advisory
Synopsis: Updated ipsec-tools package fixes vulnerabilities in ISAKMP daemon
Advisory ID: RHSA-2004:165-01
Issue date: 2004-05-11
Updated on: 2004-05-11
Product: Red Hat Enterprise Linux
Keywords: SA x509
Cross references:
Obsoletes:
CVE Names: CAN-2004-0155 CAN-2004-0164 CAN-2004-0403
----------------------------------------------------------------------
1. Topic:
An updated ipsec-tools package that fixes vulnerabilities in racoon (the ISAKMP daemon) is now available.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux ES version 3 - i386
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64
3. Problem description:
IPSEC uses strong cryptography to provide both authentication and encryption services.
With versions of ipsec-tools prior to 0.2.3, it was possible for an attacker to cause unauthorized deletion of SA (Security Associations.) The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0164 to this issue.
With versions of ipsec-tools prior to 0.2.5, the RSA signature on x.509 certificates was not properly verified when using certificate based authentication. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0155 to this issue.
When ipsec-tools receives an ISAKMP header, it will attempt to allocate sufficient memory for the entire ISAKMP message according to the header's length field. If an attacker crafts an ISAKMP header with a extremely large value in the length field, racoon may exceed operating system resource limits and be terminated, resulting in a denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0403 to this issue.
User of IPSEC should upgrade to this updated package, which contains ipsec-tools version 0.25 along with a security patch for CAN-2004-0403 which resolves all these issues.
4. Solution:
Before applying this update, make sure all previously released errata relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs.
Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the appropriate RPMs being upgraded on your system.
If up2date fails to connect to Red Hat Network due to SSL Certificate Errors, you need to install a version of the up2date client with an updated certificate. The latest version of up2date is available from the Red Hat FTP site and may also be downloaded directly from the RHN website:
https://rhn.redhat.com/help/latest-up2date.pxt
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
