Bind9/Unbound Security Updates for Debian
Posted by Philipp Esselbach on: 05/28/2011 10:43 AM [ Print | 0 comment(s) ]
The following two security updates are available for Debian: [SECURITY] [DSA 2244-1] bind9 security update and [SECURITY] [DSA 2243-1] unbound security update
[SECURITY] [DSA 2244-1] bind9 security update
- -------------------------------------------------------------------------
Debian Security Advisory DSA-2244-1 security@debian.org
http://www.debian.org/security/ Florian Weimer

- -------------------------------------------------------------------------
Package : bind9
Vulnerability : incorrect boundary condition
Problem type : remote
Debian-specific: no
CVE ID : CVE-2011-1910
It was discovered that BIND, an implementation of the DNS protocol,
does not correctly process certain large RRSIG record sets in DNSSEC
responses. The resulting assertion failure causes the name server
process to crash, making name resolution unavailable. (CVE-2011-1910)
In addition, this update fixes handling of certain signed/unsigned
zone combinations when a DLV service is used. Previously, data from
certain affected zones could become unavailable from the resolver.
For the oldstable distribution (lenny), this problem has been fixed in
version 1:9.6.ESV.R4+dfsg-0+lenny2.
For the stable distribution (squeeze), this problem has been fixed in
version 1:9.7.3.dfsg-1~squeeze2.
The testing distribution (wheezy) and the unstable distribution (sid)
will be fixed soon.
We recommend that you upgrade your bind9 packages.

[SECURITY] [DSA 2243-1] unbound security update
- -------------------------------------------------------------------------
Debian Security Advisory DSA-2243-1 security@debian.org

Package : unbound
Vulnerability : design flaw
Problem type : remote
Debian-specific: no
CVE ID : CVE-2009-4008
It was discovered that Unbound, a caching DNS resolver, ceases to
provide answers for zones signed using DNSSEC after it has processed a
crafted query. (CVE-2009-4008)
In addition, this update improves the level of DNSSEC support in the
lenny version of Unbound so that it is possible for system
administrators to configure the trust anchor for the root zone.
For the oldstable distribution (lenny), this problem has been fixed in
version 1.4.6-1~lenny1.
For the other distributions (squeeze, wheezy, sid), this problem has
been fixed in version 1.4.4-1.
We recommend that you upgrade your unbound packages.
