<ul>
<li><a name="cron"></a>
<font color="#009000"><strong>SECURITY FIX: Aug 30, 1999</strong></font><br>
In cron(8), make sure argv[] is NULL terminated in the fake popen() and
run sendmail as the user, not as root.
<a href="ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.5/common/012_cron.patch">
A source code patch exists which remedies this problem.</a>
<p>
<li><a name="miscfs"></a>
<font color="#009000"><strong>SECURITY FIX: Aug 12, 1999</strong></font><br>
The procfs and fdescfs filesystems had an overrun in their handling
of uio_offset in their readdir() routines. (These filesystems are not
enabled by default).
<a href="ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.5/common/011_miscfs.patch">
A source code patch exists which remedies this problem.</a>
<p>
<li><a name="profil"></a>
<font color="#009000"><strong>SECURITY FIX: Aug 9, 1999</strong></font><br>
Stop profiling (see profil(2)) when we execve() a new process.

<p>
<li><a name="ipsec_in_use"></a>
<font color="#009000"><strong>SECURITY FIX: Aug 6, 1999</strong></font><br>
Packets that should have been handled by IPsec may be transmitted
as cleartext. PF_KEY SA expirations may leak kernel resources.
<a
href="ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.5/common/009_ipsec_in_use.patch">

<p>
<li><a name="rc"></a>
<font color="#009000"><strong>SECURITY FIX: Aug 5, 1999</strong></font><br>
In /etc/rc, use mktemp(1) for motd re-writing, and change the find(1)
to use -execdir.
<a href="ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.5/common/008_rc.patch">
A source code patch exists which remedies this problem.</a>
<p>
<li><a name="chflags"></a>
<font color="#009000"><strong>SECURITY FIX: Jul 30, 1999</strong></font><br>
Do not permit regular users to chflags(2) or fchflags(2) on character or
block devices which they may currently be the owner of.

<p>
<li><a name="nroff"></a>
<font color="#009000"><strong>SECURITY FIX: Jul 27, 1999</strong></font><br>
Cause groff(1) to be invoked with the -S flag, when called by nroff(1),
to avoid various groff features which may be security issues.  On the
whole, this is not really a security issue, but it was discussed on
BUGTRAQ as if it is.

<li><a name="fts"></a>
<font color="#009000"><strong>RELIABILITY FIX: May 19, 1999</strong></font><br>
Programs using fts(3) could dump core when given a directory structure
with a very large number of entries.

<p>
<li><a name="tcpsack"></a>
<font color="#009000"><strong>RELIABILITY FIX: May 19, 1999</strong></font><br>
Sequence numbers could wrap with TCP_SACK and TCP_NEWRENO, resulting in
failure to retransmit correctly.

Retransmitted TCP packets could get corrupted when flowing over an
IPSEC ESP tunnel.

<li><a name="bmap"></a>
<font color="#009000"><strong>RELIABILITY FIX</strong></font><br>
A local user can crash the system by reading a file larger than 64meg 
from an ext2fs partition.

<p>
<li><a name="pfkey"></a>
<font color="#009000"><strong>RELIABILITY FIX</strong></font><br>
PF_KEY socket operations leak internal kernel resources, so that a
system running an IPsec key management daemon like photurisd or isakmpd
will cause the networking subsystem to stop working after a finite amount
of time.

<font color="#009000"><strong>Y2K FIX: Aug 30, 1999</strong></font><br>
This patch corrects various OpenBSD/i386 2.5 problems with Y2K. The 2.6
release (released at 1 Dec 1999) has this problem solved. This patch is
just a workaround.

the kernel crashed.

The mac68k install utils were mistakenly left off the CD and out of
the FTP install directories.  These tools have now been added to the
FTP install directories.  See
