• 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.
  

• 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.
  

• 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.
  

• 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.
  

• 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.
  

• 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.
  

• 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.
  

• 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.
  

• 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.
  

• 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.
  

• 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.
  

• 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.
  

• 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.
