Fw: ISS Security Advisory: Multiple Remote Vulnerabilities in BIND4 and BIND8 (fwd)

Wed Nov 13 10:49:56 GMT 2002

Hello,

AFAIK -STABLE & -CURRENT have 8.3.3-REL in the base system.
The latest release of BIND8(8.x branch) according to
http://www.isc.org/products/BIND/ is 8.3.3. 
I personally suggest, masking bind version until fix is available,
+everybody that uses bind with Round Robin should chroot it (at least).

G`luck

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
