Patches for the OpenBSD base system are distributed as unified diffs.
Each patch contains usage instructions.
All the following patches are also available in one
tar.gz file
for convenience.
Patches for supported releases are also incorporated into the
-stable branch.
-
001: SECURITY FIX: June 7, 2005
All architectures
Fix a buffer overflow, memory leaks, and NULL pointer dereference in
cvs(1)
. None of these issues are known to be exploitable.
CAN-2005-0753
.
A source code patch exists which remedies this problem.
-
002: RELIABILITY FIX: June 15, 2005
All architectures
As discovered by Stefan Miltchev calling
getsockopt(2)
to get
ipsec(4)
credentials for a socket can result in a kernel panic.
A source code patch exists which remedies this problem.
-
003: SECURITY FIX: June 20, 2005
All architectures
Due to a race condition in its command pathname handling, a user with
sudo(8)
privileges may be able to run arbitrary commands if the user's entry
is followed by an entry that grants sudo ALL privileges to
another user.
A source code patch exists which remedies this problem.
-
004: SECURITY FIX: July 6, 2005
All architectures
A buffer overflow has been found in
compress(3)
which may be exploitable.
A source code patch exists which remedies this problem.
-
005: SECURITY FIX: July 21, 2005
All architectures
A buffer overflow has been found in
compress(3)
which may be exploitable.
Please note that this fixes a different buffer overflow than the previous zlib patch.
A source code patch exists which remedies this problem.
-
006: RELIABILITY FIX: November 5, 2005
All architectures
Due to wrong advertisement of RFC 3947 compliance interoperability problems with
isakmpd(8)
may occur.
A source code patch exists which remedies this problem.
-
007: SECURITY FIX: January 5, 2006
All architectures
A buffer overflow has been found in the Perl interpreter with the sprintf function which
may be exploitable under certain conditions.
A source code patch exists which remedies this problem.
-
008: SECURITY FIX: January 5, 2006
All architectures
Do not allow users to trick suid programs into re-opening files via /dev/fd.
A source code patch exists which remedies this problem.
-
009: RELIABILITY FIX: January 13, 2006
i386 architecture
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
mprotect(2)
and
mmap(2)
requests need it to. This is now implemented using only GDT selectors
instead of the LDT so that it is more robust as well.
A source code patch exists which remedies this problem.
-
010: RELIABILITY FIX: January 13, 2006
i386 architecture
Constrain
i386_set_ioperm(2)
so even root is blocked from accessing the ioports
unless the machine is running at lower securelevels or with an open X11 aperture.
A source code patch exists which remedies this problem.
-
011: SECURITY FIX: February 12, 2006
All architectures
Josh Bressers has reported a weakness in OpenSSH caused due to the insecure use of the
system(3)
function in
scp(1)
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
scp(1).
A source code patch exists which remedies this problem.
-
012: SECURITY FIX: March 25, 2006
All architectures
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.
A source code patch exists which remedies this problem.
-
013: SECURITY FIX: May 2, 2006
All architectures
A security vulnerability has been found in the X.Org server –
CVE-2006-1526.
Clients authorized to connect to the X server are able to crash it and to execute
malicious code within the X server.
A source code patch exists which remedies this problem.
