Internet Security Systems Security Brief November 12, 2002

Multiple Remote Vulnerabilities in BIND4 and BIND8

Synopsis:

ISS X-Force has discovered several serious vulnerabilities in the Berkeley Internet Name Domain Server (BIND). BIND is the most common implementation of the DNS (Domain Name Service) protocol, which is used on the vast majority of DNS servers on the Internet. DNS is a vital Internet protocol that maintains a database of easy-to-remember domain names (host names) and their corresponding numerical IP addresses.

Impact:

The vulnerabilities described in this advisory affect nearly all currently deployed recursive DNS servers on the Internet. The DNS network is considered a critical component of Internet infrastructure. There is no information implying that these exploits are known to the computer underground, and there are no reports of active attacks. If exploits for these vulnerabilities are developed and made public, they may lead to compromise and DoS attacks against vulnerable DNS servers. Since the vulnerability is widespread, an Internet worm may be developed to propagate by exploiting the flaws in BIND. Widespread attacks against the DNS system may lead to general instability and inaccuracy of DNS data.

Affected Versions:

BIND SIG Cached RR Overflow Vulnerability

    BIND 8, versions up to and including 8.3.3-REL
    BIND 4, versions up to and including 4.9.10-REL

BIND OPT DoS

    BIND 8, versions 8.3.0 up to and including 8.3.3-REL

BIND SIG Expiry Time DoS

    BIND 8, versions up to and including 8.3.3-REL
