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: 3.6
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated libldb packages that fix two security issues are now available for Red Hat Gluster Storage 3.1.
Red Hat Product Security 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.
The libldb packages provide an extensible library that implements an LDAP-like API to access remote LDAP servers, or use local TDB databases.
A denial of service flaw was found in the ldb_wildcard_compare() function of libldb. A remote attacker could send a specially crafted packet that, when processed by an application using libldb (for example the AD LDAP server in Samba), would cause that application to consume an excessive amount of memory and crash. (CVE-2015-3223)
A memory-read flaw was found in the way the libldb library processed LDB DN records with a null byte. An authenticated, remote attacker could use this flaw to read heap-memory pages from the server.
Red Hat would like to thank the Samba project for reporting these issues. Upstream acknowledges Thilo Uttendorfer as the original reporter of CVE-2015-3223, and Douglas Bagnall as the original reporter of CVE-2015-5330.
All libldb users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
