<strong>002: RELIABILITY FIX: June 15, 2005</strong>

<a href="https://man.openbsd.org/OpenBSD-3.7/ipsec.4">ipsec(4)</a>

<strong>003: SECURITY FIX: June 20, 2005</strong>
&nbsp; <i>All architectures</i><br>
Due to a race condition in its command pathname handling, a user with
<a href="https://man.openbsd.org/OpenBSD-3.7/sudo.8">sudo(8)</a>

is followed by an entry that grants <code>sudo ALL</code> privileges to
another user.

<strong>009: RELIABILITY FIX: January 13, 2006</strong>
&nbsp; <i>i386 architecture</i><br>
Change the implementation of i386 W^X so that the "execute line" can move around.
Before it was limited to being either at 512MB (below which all code normally
lands) or at the top of the stack. Now the line can float as
<a href="https://man.openbsd.org/OpenBSD-3.7/mprotect.2">mprotect(2)</a>
and
<a href="https://man.openbsd.org/OpenBSD-3.7/mmap.2">mmap(2)</a>
requests need it to. This is now implemented using only GDT selectors
instead of the LDT so that it is more robust as well.

<strong>011: SECURITY FIX: February 12, 2006</strong>
&nbsp; <i>All architectures</i><br>
Josh Bressers has reported a weakness in OpenSSH caused due to the insecure use of the
<a href="https://man.openbsd.org/OpenBSD-3.7/system.3">system(3)</a>
function in
<a href="https://man.openbsd.org/OpenBSD-3.7/scp.1">scp(1)</a>
when performing copy operations using filenames that are supplied by the user from the command line.
This can be exploited to execute shell commands with privileges of the user running
<a href="https://man.openbsd.org/OpenBSD-3.7/scp.1">scp(1)</a>.

<li id="sendmail">
<strong>012: SECURITY FIX: March 25, 2006</strong>

A race condition has been reported to exist in the handling by sendmail of
asynchronous signals. A remote attacker may be able to execute arbitrary code with the
privileges of the user running sendmail, typically root.
