The remote host is missing an update to ilohamail announced via advisory DSA 1010-1. Ulf Härnhammar from the Debian Security Audit Project discovered that ilohamail, a lightweight multilingual web-based IMAP/POP3 client, does not always sanitise input provided by users which allows remote attackers to inject arbitrary web script or HTML. The old stable distribution (woody) does not contain an ilohamail package.
For the stable distribution (sarge) these problems have been fixed in version 0.8.14-0rc3sarge1. For the unstable distribution (sid) these problems have been fixed in version 0.8.14-0rc3sarge1. We recommend that you upgrade your ilohamail package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%201010-1
