<bug_vulnerability_class>Buffer Overflow</bug_vulnerability_class>
<bug_description>The remote host is running an Apache web server. Apache prior 2.0.50 which is vulnerable to a buffer overflow in the mod_ssl module. This issue is exposed in utility code for uuencoding binary data. As SecurityFocus.com describes, "this issue would most likely result in a denial of service if triggered, but could theoretically allow for execution of arbitrary code. The issue is not believed to be exploitable to execute arbitrary code on x86 architectures, though this may not be the case with other architectures."</bug_description>
<bug_solution>If the web server is not used it should be de-installed or de-activated. Install the newest patch or bugfix to solve the problem or upgrade to the latest software version which is not vulnerable anymore. To make it harder to find the server the daemon could be configured to listen at another port (e.g. 8081). Alternation of the application banner can confuse an attacker and let him determine the wrong software. Additionally limit unwanted connections and communications with firewalling.</bug_solution>
