RHSA-2004-165: ipsec Vulnerability Scan
Vulnerability Scan Summary
Check for the version of the ipsec packages
Detailed Explanation for this Vulnerability Test
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 CVE-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 CVE-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 a possible hacker 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
CVE-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 CVE-2004-0403
which resolves all these issues.
