The remote Red Hat host is missing one or more security updates.
Version 9 of ISC BIND, prior to version 9.2.1, contained a denial of
service (DoS) attack vulnerability. Various versions of the ISC BIND
resolver libraries are vulnerable to a buffer overflow attack.
ISC BIND (Berkeley Internet Name Domain) is an implementation of the
DNS (Domain Name System) protocols. BIND includes a DNS server (named)
-- which resolves hostnames to IP addresses, a resolver library
(routines for applications to use when interfacing with DNS), and
Versions of BIND 9 prior to 9.2.1 have a bug that causes certain
requests to the BIND name server to fail an internal consistency
check, causing the name server to stop responding to requests. This
can be used by a remote attacker to cause a denial of service (DoS)
attack against name servers. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CVE-2002-0400 to this
A buffer overflow vulnerability exists in multiple implementations of
DNS resolver libraries. Applications that utilize vulnerable DNS
resolver libraries may be affected. A remote attacker who is able to
send malicious DNS responses could potentially exploit this
vulnerability to execute arbitrary code or cause a denial of service
(DoS) attack on a vulnerable system. Red Hat Linux does not ship with
any applications or libraries that link against the BIND resolver
libraries; however, third party code may be affected. (CVE-2002-0651)
Red Hat Linux Advanced Server shipped with a version of ISC BIND
vulnerable to both of these issues. All users of BIND are advised to
upgrade to the errata packages containing BIND 9.2.1 which contains
backported patches that correct these issues.
