Ubuntu 7.04 : tcp-wrappers vulnerability (USN-507-1)

medium Nessus Plugin ID 28111

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

It was discovered that the TCP wrapper library was incorrectly allowing connections to services that did not specify server-side connection details. Remote attackers could connect to services that had been configured to block such connections. This only affected Ubuntu Feisty.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libwrap0, libwrap0-dev and / or tcpd packages.
