The remote host is missing an update to evolution announced via advisory DSA 1016-1. Ulf Härnhammar discovered several format string vulnerabilities in Evolution, a free groupware suite, that could lead to crashes of the application or the execution of arbitrary code. For the old stable distribution (woody) these problems have been fixed in version 1.0.5-1woody3.
For the stable distribution (sarge) these problems have been fixed in version 2.0.4-2sarge1. For the unstable distribution (sid) these problems have been fixed in version 2.2.3-3. We recommend that you upgrade your evolution package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%201016-1
