pdns-recursor - predictable randomness

Amit Klein discovered that pdns-recursor, a caching DNS resolver, uses a
weak random number generator to create DNS transaction IDs and UDP
source port numbers. As a result, cache poisoning attacks were
simplified. (CVE-2008-1637
and CVE-2008-3217)

For the stable distribution (etch), these problems have been fixed in
version 3.1.4-1+etch2.

For the unstable distribution (sid), these problems have been fixed in
version 3.1.7-1.

We recommend that you upgrade your pdns-recursor package.
