Base vector

AV:N/AC:L/Au:N/C:N/I:N/A:P

Name of the Vulnerable Software and Affected Versions: DenyHosts versions prior to 2.6

Description: The issue allows remote attackers to cause a denial of service by adding arbitrary IP addresses to the sshd log file. This can be achieved by logging in via ssh with a login name containing certain strings with an IP address, which is not properly handled by a regular expression. The vulnerability can lead to disruption of access to protected information and can be exploited remotely.

Recommendations: For DenyHosts versions prior to 2.6, update to version 2.6 or later to resolve the issue. As a temporary workaround, consider restricting access to the sshd log file to minimize the risk of exploitation.
