It was discovered that BIND, a DNS server, does not correctly process certain UPDATE requests, resulting in a server crash and a denial of service. This vulnerability affects BIND installations even if they do not actually use dynamic DNS updates.
For the oldstable distribution (lenny), this problem has been fixed in version 1:9.6.ESV.R4+dfsg-0+lenny3.
For the stable distribution (squeeze), this problem has been fixed in version 1:9.7.3.dfsg-1~squeeze3.
The testing distribution (wheezy) and the unstable distribution (sid) will be fixed later.
We recommend that you upgrade your bind9 packages.
