Package        : bind9
Version        : 9.7.3.dfsg-1~squeeze15
CVE ID         : CVE-2015-4620
Debian Bug     : 791715

A vulnerability has been found in the Internet Domain Name Server bind9:

CVE-2015-4620

    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.
