Package description:

neon is an HTTP and WebDAV client library for Unix systems, with a C language API. It provides high-level interfaces to HTTP/1.1 and WebDAV methods, and a low-level interface to HTTP request/response handling, allowing new methods to be easily implemented.

Problem description:

Multiple format string vulnerabilities in neon 0.24.4 and earlier, and the cadaver client which uses neon, as used in OpenOffice, allow remote malicious WebDAV servers to execute arbitrary code.

Action:

We recommend that all systems with this package installed be upgraded. Please note that if you do not need the functionality provided by this package, you may want to remove it from your system.

About Linux Netwosix:

Linux Netwosix is a powerful and optimized Linux distribution for servers and Network Security related jobs. It can also be used for special operations such as penetration testing with its big collection of security oriented software and sources. It's a light distribution created for the requirements of every SysAdmin and it's very portable and highly configurable. Our philosophy is to give greater liberty for configuration to the SysAdmin. Only in this way can he/she configure a powerful and stable server machine. Linux Netwosix also has a powerful ports system (Nepote) similar to the xBSD systems but more flexible and usable.

Netwosix Linux Security Advisory #2004-0011 <http://www.netwosix.org>

---

Package name: cvs
Summary: client and server vulnerabilities
Date: 2004-04-18
Affected versions: Netwosix 1.0 Netwosix 1.1

---

Package description:

CVS is the Concurrent Versions System, the dominant open-source network-transparent version control system. CVS is useful for everyone from individual developers to large, distributed teams:

• Its client-server access method lets developers access the latest code from anywhere there's an Internet connection.
• Its unreserved check-out model to version control avoids artificial conflicts common with the exclusive check-out model.
• Its client tools are available on most platforms.

Problem description:

SERVER SECURITY ISSUES

• Piped checkouts of paths above $CVSROOT no longer work. Previously, clients could have requested the contents of RCS archive files anywhere on a CVS server.

CLIENT SECURITY ISSUES

• Clients now check paths from the server to verify that they are within one of the sandboxes the user requested be updated. Previously, a trojan server could have written or overwritten files anywhere the user had access, presenting a serious security risk.

Action:

We recommend that all systems with this package installed be upgraded. Please note that if you do not need the functionality provided by this package, you may want to remove it from your system.
