bind security update (RHSA-2007-0044)

Original Release Date: March 27, 2007
Last Revised: July 1, 2009
Number: ASA-2007-125
Risk Level: Low
Advisory Version: 3.0
Advisory Status: Interim

1. Overview:

Berkeley Internet Name Domain (BIND) provides tools and a server for the Domain Name System (DNS) protocols.

BIND was found to contain a bug in the way it handled specific types of DNS query responses. A remote attacker could possibly cause a remote Denial of Service (DoS) condition on servers using DNSSEC validation. A flaw was found in the way BIND processed certain DNS query responses. On servers that had enabled DNSSEC validation, this could allow a remote attacker to cause a denial of service. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2007-0494 to this issue.

More information about these vulnerabilities can be found in the security advisory issued by RedHat Linux:
