"Upgrade the openssl packages.

For the stable distribution (lenny), this problem has been fixed in
version 0.9.8g-15+lenny5.

For the old stable distribution (etch), this problem has been fixed in
version 0.9.8c-4etch9 for openssl and version 0.9.7k-3.1etch5 for
openssl097. The OpenSSL 0.9.8 update for oldstable (etch) also
provides updated packages for multiple denial of service
vulnerabilities in the Datagram Transport Layer Security
implementation. These fixes were already provided for Debian stable
(Lenny) in a previous point update. The OpenSSL 0.9.7 package from
oldstable (Etch) is not affected. (CVE-2009-1377, CVE-2009-1378,
CVE-2009-1379, CVE-2009-1386 and CVE-2009-1387 )"
