Вт Ноя 12 20:41:18 MSK 2002

Greetings!

Поступила информация, которую я считаю необходимым сообщить вам
безотлагательно, несмотря на то, что исправления на данный момент не
доступны.

Как сказал по этому случаю Alan Cox, цитирую,
"Well we can all express our deep regret at the inability of the
ironically named ISC to work with the internet and society in all the
announces."

О доступности исправлений будет сообщено дополнительно.

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
