An improper bounds check makes it possible for a local user to cause a crash
by passing the
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=semctl&apropos=0&sektion=2&manpath=OpenBSD+Current&arch=i386&format=html">semctl(2)</a> and
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=semop&apropos=0&sektion=2&manpath=OpenBSD+Current&arch=i386&format=html">semop(2)</a> functions
certain arguments.

A user with write permission to <tt>httpd.conf</tt> or a <tt>.htaccess</tt>
file can crash
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=httpd&sektion=8">httpd(8)</a>
or potentially run arbitrary code as the user <tt>www</tt> (although it
is believed that ProPolice will prevent code execution).

The use of certain ASN.1 encodings or malformed public keys may allow an
attacker to mount a denial of service attack against applications linked with
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssl&sektion=3">ssl(3)</a>.
This does not affect OpenSSH.<br>

<li><font color="#009000"><strong>001: DOCUMENTATION FIX: November 1, 2003</strong></font><br>
The CD insert documentation has an incorrect example for package installation.<br>
Where it is written:<p>
<strong>
# pkg_add ftp://ftp.openbsd.org/pub/OpenBSD/3.4/packages/i386</strong><p>
It should instead read:<p>
<strong>
# pkg_add ftp://ftp.openbsd.org/pub/OpenBSD/3.4/packages/i386/</strong><p>
The extra <strong>/</strong> at the end is important. We do not make
patch files available for things printed on paper.

It may be possible for a local user to overrun the stack in

ProPolice catches this, turning a potential privilege escalation into a denial
of service. iBCS2 emulation does not need to be enabled via
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sysctl&sektion=8&apropos=0&manpath=OpenBSD+Current&arch=i386">sysctl(8)</a>
for this to happen.
