Debian Security Advisory DSA-2517-1 [email protected]
http://www.debian.org/security/ Nico Golde
July 30, 2012 http://www.debian.org/security/faq
Package : bind9
Vulnerability : denial of service
Problem type : remote
Debian-specific: no
CVE ID : CVE-2012-3817
Einar Lonn discovered that under certain conditions bind9, a DNS server,
may use cached data before initialization. As a result, an attacker can
trigger and assertion failure on servers under high query load that do
DNSSEC validation.
For the stable distribution (squeeze), this problem has been fixed in
version 1:9.7.3.dfsg-1~squeeze6.
For the testing distribution (wheezy), this problem will be fixed soon.
For the unstable distribution (sid), this problem has been fixed in
version 1:9.8.1.dfsg.P1-4.2.
We recommend that you upgrade your bind9 packages.
