- Security database references:
- In Mitre's CVE dictionary: CVE-2012-3817.
- More information:
Einar Lonn discovered that under certain conditions bind9, a DNS server, may use cached data before initialization. As a result, an attacker can trigger an 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.
