Security Advisory ipsec-tools security update

Advisory: RHSA-2004:165-09
Type: Security Advisory
Severity: Important
Issued on: 2004-05-11
Last updated on: 2004-05-11
Affected Products: Red Hat Enterprise Linux AS (v. 3)
Red Hat Enterprise Linux ES (v. 3)

CVEs (cve.mitre.org): CVE-2004-0155
CVE-2004-0164
CVE-2004-0403

Details

An updated ipsec-tools package that fixes vulnerabilities in racoon (the
ISAKMP daemon) is now available.

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.


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:
