New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 6.7
SynopsisThe remote Oracle Linux host is missing one or more security updates.
DescriptionFrom Red Hat Security Advisory 2010:0543 :
Updated openldap packages that fix two security issues are now available for Red Hat Enterprise Linux 4.
The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
OpenLDAP is an open source suite of LDAP (Lightweight Directory Access Protocol) applications and development tools.
An uninitialized pointer use flaw was discovered in the way the slapd daemon handled modify relative distinguished name (modrdn) requests.
An authenticated user with privileges to perform modrdn operations could use this flaw to crash the slapd daemon via specially crafted modrdn requests. (CVE-2010-0211)
Red Hat would like to thank CERT-FI for responsibly reporting the CVE-2010-0211 flaw, who credit Ilkka Mattila and Tuomas Salomaki for the discovery of the issue.
A flaw was found in the way OpenLDAP handled NUL characters in the CommonName field of X.509 certificates. An attacker able to get a carefully-crafted certificate signed by a trusted Certificate Authority could trick applications using OpenLDAP libraries into accepting it by mistake, allowing the attacker to perform a man-in-the-middle attack. (CVE-2009-3767)
Users of OpenLDAP should upgrade to these updated packages, which contain backported patches to resolve these issues. After installing this update, the OpenLDAP daemons will be restarted automatically.
SolutionUpdate the affected openldap packages.
