CVE-2005-0877
Description
From CVE.org
Dnsmasq before 2.21 allows remote attackers to poison the DNS cache via answers to queries that were not made by Dnsmasq.
Statement
RHOSP deployments are not affected because they pull dnsmasq directly from the rhel-7-server channel. A RHOSP dnsmasq update will therefore not be provided at this time. All RHEL versions are not affected because they have the updated/fixed dnsmasq.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
