Description:	Summary: The remote host is missing an update to pdns-recursor announced via advisory DSA 1544-1. This VT has been deprecated and merged into the VT 'Debian: Security Advisory (DSA-1544)' (OID: 1.3.6.1.4.1.25623.1.0.61360). Vulnerability Insight: 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) For the stable distribution (etch), these problems have been fixed in version 3.1.4-1+etch1. For the unstable distribution (sid), these problems have been fixed in version 3.1.5-1. Solution: We recommend that you upgrade your pdns-recursor package. CVSS Score: 6.8 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:P/A:P
