- Security database references:
- In the Debian bugtracking system: Bug 791715.

- More information:
A vulnerability has been found in the Internet Domain Name Server bind9:
Breno Silveira Soares of Servico Federal de Processamento de Dados (SERPRO) discovered that the BIND DNS server is prone to a denial of service vulnerability. A remote attacker who can cause a validating resolver to query a zone containing specifically constructed contents can cause the resolver to terminate with an assertion failure, resulting in a denial of service to clients relying on the resolver.
For the squeeze distribution, these issues have been fixed in version 9.7.3.dfsg-1~squeeze15 of bind9.
We recommend that you upgrade your bind9 packages.
