It was discovered that BIND, a DNS server, crashes while processing certain sequences of recursive DNS queries, leading to a denial of service. Authoritative-only server configurations are not affected by this issue.


Upgrade the bind9 packages.

For the oldstable distribution (lenny), this problem has been fixed in version 1:9.6.ESV.R4+dfsg-0+lenny4.

For the stable distribution (squeeze), this problem has been fixed in version 1:9.7.3.dfsg-1~squeeze4.
