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

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

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.

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.

Solution

Run 'yum update libldb' to update your system.
