38: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
39: Vulnerabilities have been found in the X11, Xt, Xaw and Xmu
40: libraries. These affect xterm and all other setuid-root programs that
41: use these libraries. The problems are associated with buffer overflows
42: in code that processes user-supplied data. The Xt library problems
43: include those fixed in TOG's recent public patch 3 for X11R6.3. All
44: releases of XFree86 up to and including 3.3.2 patch 1 and the version
45: distributed with OpenBSD are vulnerable to some or all of these
46: problems.
1.121 deraadt 47: These problems are fixed in XFree86 patch 2.
48: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/XFree86-3.3.2.2.patch>
49: A source patch</a> for these problems, specifically adapted to the
50: OpenBSD 2.3 X11 tree, is available now.
1.120 matthieu 51: <p>
1.116 deraadt 52: <a name=kill></a>
53: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
54: The kill(2) system call previously would permit a large set of signals to
55: be delivered to setuid or setgid processes. If such processes were using
56: those signals in dubious ways, this could have resulted in security
57: problems of various kinds.
58: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/kill.patch>
1.125 deraadt 59: The fourth revision of a source code patch which solves the problem is
1.117 deraadt 60: available.</a>
1.116 deraadt 61: <p>
1.108 deraadt 62: <a name=immutable></a>
63: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
1.109 deraadt 64: A possible new security problem exists if you rely on securelevels and
65: immutable or append-only files or character devices. The fix does not
66: permit mmap'ing of immutable or append-only files which are otherwise
67: writeable, as the VM system will bypass the meaning of the file flags
68: when writes happen to the file.
1.108 deraadt 69: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/immutable.patch>
70: A source code patch exists which remedies this problem.</a>
71: <p>
1.102 deraadt 72: <a name=ipsec></a>
73: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
74: If IPSEC communication is attempted by starting photurisd(8) (which is
1.103 deraadt 75: disabled by default), a system crash may be evoked from remote if
76: an attacker uses some classes of invalid packets.
1.102 deraadt 77: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/ipsec.patch>
78: A source code patch exists which remedies this problem.</a>

1.99 matthieu 80: <a name=xterm-xaw></a>
81: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
82: As stated in CERT advisory VB-98.04, there are buffer
1.103 deraadt 83: overrun problems in <strong>xterm</strong> related to the input-Method,
84: preeditType, and *Keymap resources. Additional buffer overruns exist in
85: the <strong>Xaw</strong> library related to the inputMethod and
86: preeditType resources. The xterm(1) problem represents a security
87: vulnerability for any platform where xterm is installed setuid-root
88: (as is the case for all OpenBSD platforms). The Xaw problem represents
89: a security vulnerability for any setuid-root program that uses the Xaw
90: library (including xterm). Patch1 from XFree86 3.3.2 corrects
91: these problems.
1.99 matthieu 92: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/xterm-xaw.patch>
1.101 deraadt 93: We provide a version of this patch file specifically for the OpenBSD 2.3 tree</a>.
1.107 deraadt 94: We also provide tar files which replace the xterm(1) binary and the libXaw
95: libraries on your system. These are expected to be extracted in
96: <strong>/usr/X11R6</strong> using the command
97: <strong>"tar xvfpz Xawfix.tgz"</strong>.

116: The pctr(4) driver has bugs that permit any user to crash the machine,
117: if the CPU is not an Intel CPU. This problem has been properly fixed
118: since, but fixes are hard to apply to the 2.2 or 2.3 releases. To avoid
119: the problem, recompile your kernel without the pctr(4) device driver.
