The Honeynet report on Linux life expectancy

Numerous electrons have been expended on the recently-released Honeynet report (PDF) on the life expectancy of systems exposed to the Internet. That report concluded that an unpatched Linux system would last, on the average, for about three months before being compromised, while a Windows system had a life expectancy measured in hours. That is an outcome which is certainly welcome to those who are concerned about the security of Linux systems.

If you actually read the report, however, you'll find some interesting things. The test, it would seem, was set up in a way designed to make the Linux systems as easy as possible to compromise. Among other things:

  • The Linux distributions installed were old: Red Hat Linux 7.2, SUSE Linux 6.3, etc. The most current distribution installed was Fedora Core 1, put on two boxes (neither of which was compromised)..

  • These systems had a number of services installed; some of those (i.e. SMB) are not necessarily something one would enable on systems directly connected to the net.

  • The systems were set up with easily guessed passwords as well.

Of the four Linux systems which were compromised, two of them fell to brute-force password guessing. This episode may be a good lesson in why choosing good passwords is still important, but it has nothing to do with Linux security.

The report authors note that the expected lifetime of Linux systems has increased - an interesting development, given that the net has not exactly become a friendlier place. The authors guess, as usual, that the relative popularity of Windows makes it a more attractive target. They also note, however, that default Linux installations have become more secure over time. Certainly much effort has gone toward that end; it is nice to see that it is having an effect.

iptables: missing initialization

Package(s):iptables CVE #(s):CAN-2004-0986
Created:November 1, 2004 Updated:February 11, 2005
Description: Faheem Mitha noticed that the iptables command, an administration tool for IPv4 packet filtering and NAT, did not always load the required modules on its own as it was supposed to. This could lead to firewall rules not being loaded on system startup. This caused a failure in connection with rules provided by lokkit at least.

kernel-utils: setuid vulnerability

Package(s):kernel-utils CVE #(s):CAN-2003-0019
Created:February 7, 2003 Updated:January 21, 2005
Description: The kernel-utils package contains several utilities that can be used to control the kernel or machine hardware. In Red Hat Linux 8.0 this package contains user mode linux (UML) utilities.

The uml_net utility in kernel-utils packages with Red Hat Linux 8.0 was incorrectly shipped setuid root. This could allow local users to control certain network interfaces, add and remove arp entries and routes, and put interfaces in and out of promiscuous mode.

All users of the kernel-utils package should update to these packages that contain a version of uml_net that is not setuid root.

Alternatively, as a work-around to this vulnerability issue the following command as root:

chmod -s /usr/bin/uml_net

libgd2: buffer overflows in PNG handling

Package(s):libgd2 CVE #(s):CAN-2004-0990 CAN-2004-0941
Created:October 29, 2004 Updated:June 28, 2006
Description: Several buffer overflows have been discovered in libgd's PNG handling functions.
If an attacker tricked a user into loading a malicious PNG image, they could leverage this into executing arbitrary code in the context of the user opening image. Most importantly, this library is commonly used in PHP. One possible target would be a PHP driven photo website that lets users upload images. Therefore this vulnerability might lead to privilege escalation to a web server's privileges.
Multiple buffer overflows in the gd graphics library (libgd) 2.0.21 and earlier may allow remote attackers to execute arbitrary code via malformed image files that trigger the overflows due to improper calls to the gdMalloc function.
