The remote host is missing an update to razor announced via advisory DSA 738-1. A vulnerability was discovered in the way that Razor parses certain email headers that could potentially be used to crash the Razor program, causing a denial of service (DOS).

For the stable distribution (sarge), this problem has been fixed in version 2.670-1sarge2. The old stable distribution (woody) is not affected by this issue. We recommend that you upgrade your razor package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20738-1
