1.47 tb 54: This is a partial list of new features and systems included in OpenBSD 3.3.
1.18 deraadt 55: For a comprehensive list, see the <a href="plus33.html">changelog</a> leading
1.1 miod 56: to 3.3.
57: <p>

59: <ul>
60: <li>Integration of the
1.30 david 61: <a href="http://www.research.ibm.com/trl/projects/security/ssp/">ProPolice</a>
1.26 deraadt 62: stack protection technology, by Hiroaki Etoh, into the system
63: compiler. This protection is enabled by default. With this change,
64: function prologues are modified to rearrange the stack: a random
65: canary is placed before the return address, and buffer variables are
66: moved closer to the canary so that regular variables are below, and
67: harder to smash. The function epilogue then checks if the canary is
68: still intact. If it is not, the process is terminated. This change
69: makes it very hard for an attacker to modify the return address used
70: when returning from a function.
1.2 deraadt 71: <p>
1.1 miod 72:
1.22 deraadt 73: <li>W^X (pronounced: "W xor X") on architectures capable of
1.10 deraadt 74: pure execute-bit support in the MMU (sparc, sparc64, alpha,
75: hppa). This is a fine-grained memory permissions layout, ensuring that
76: memory which can be written to by application programs can not be
1.22 deraadt 77: executable at the same time and vice versa. This raises the bar on
78: potential buffer overflows and other attacks: as a result, an attacker
79: is unable to write code anywhere in memory where it can be executed.
1.26 deraadt 80: (NOTE: i386 and powerpc do not support W^X in 3.3; however, 3.3-current
81: already supports it on i386, and both these processors are expected to
1.47 tb 82: support this change in 3.4).
1.1 miod 83: <p>
84:
1.2 deraadt 85: <li>Still more reduction in setuid and setgid binaries, and more chroot
1.22 deraadt 86: use throughout the system. While some programs are still setuid or
87: setgid, almost all of them grab a resource and then quickly revoke
88: privilege.
1.1 miod 89: <p>
90:
1.22 deraadt 91: <li>The X window server and xconsole now use privilege separation,
92: for better security. Also, xterm has been modified to do privilege
93: revocation. xdm runs as a special user and group, to further constrain
94: what might go wrong.
1.1 miod 95: <p>
96:
97: <li>As usual, improvements to the documentation, notably the man pages and
1.7 jsyn 98: the Web FAQ. An increasingly large part of the website is available in several
1.1 miod 99: languages.
100: <p>
101:
102: <li>More complete collection and better tested set of "ports".
103: setuid/setgid ports have been significantly reduced as well. Many of the
104: ones that remain setuid have been modified to revoke privileges as early
105: as possible.
106: <p>
107:
108: <li>Over 2000 pre-built and tested packages.
109: <p>
110:
111: <li>Significant improvements to the pthread library.
112: <p>
113:

124: <li>TCP window scaling support

1.22 deraadt 129: a spam deferral daemon, which SMTP connections can be redirected to.
130: This daemon handles connections based on black lists and white lists,
131: tar-pits the connections, and ensures that the spammer knows why their
132: mail has not been accepted.

211: Play with your BIOS options to enable booting from a CD. The OpenBSD/i386
212: release is on CD1. If your BIOS does not support booting from CD, you will need
213: to create a boot floppy to install from. To create a boot floppy write
214: <i>CD1:3.3/i386/floppy33.fs</i> to a floppy and boot via the floppy drive.
215:
216: <p>
217: Use <i>CD1:3.3/i386/floppyB33.fs</i> instead for greater scsi controller
218: support, or <i>CD1:3.3/i386/floppyC33.fs</i> for better laptop support.
219:
220: <p>
221: If you are planning on dual booting OpenBSD with another OS, you will need to read the included INSTALL.i386 document.
222:
223: <p>
224: To make a boot floppy under MS-DOS, use the "rawrite" utility located
1.46 sthen 225: at <i>CD:/3.3/tools/rawrite.exe</i>. To make the boot floppy under a Unix OS, use the <a href="http://man.openbsd.org/?query=dd&sektion=1">dd(1)</a> utility. The following is an example usage of <a href="http://man.openbsd.org/?query=dd&sektion=1">dd(1)</a>, where the device could be "floppy", "rfd0c", or "rfd0a".
