! 033: SECURITY FIX: September 11, 2001 ! All architectures
! A security hole exists in uuxqt(8) ! that may allow an attacker to run arbitrary commands as user uucp and ! use this to gain root access. ! The UUCP execution daemon, uuxqt(8), has a bug in its command line ! parsing routine may allow arbitrary commands to be run. Because ! some UUCP commands are run as root (and daemon) from cron it is possible ! to leverage compromise of the UUCP user to gain root. !
! A source code patch exists which remedies this problem.
!
! 032: SECURITY FIX: August 29, 2001 All architectures
! A security hole exists in lpd(8) ! that may allow an attacker with line printer access to gain root ! privileges. A machine must be running lpd to be vulnerable (OpenBSD ! does not start lpd by default). Only machines with line printer ! access (ie: listed in either /etc/hosts.lpd or /etc/hosts.equiv) ! may be used to mount an attack. !
! A source code patch exists which remedies this problem.

! 031: SECURITY FIX: August 21, 2001 ! All architectures
! A security hole exists in sendmail(8) ! that may allow an attacker on the local host to gain root privileges by ! specifying out-of-bounds debug parameters. !
! A source code patch exists which remedies this problem.

! 030: SECURITY FIX: June 15, 2001 All architectures
! A race condition exists in the kernel execve(2) implementation that opens a small window of vulnerability for a non-privileged user to ptrace(2) attach to a suid/sgid process. !
! A source code patch exists which remedies this problem.
!
! 029: SECURITY FIX: May 30, 2001 All architectures
! Programs using the fts(3) ! routines (such as rm, find, and most programs that take a -R ! flag) can be tricked into changing into the wrong directory if the ! parent dir is changed out from underneath it. This is similar to ! the old fts bug but happens when popping out of directories, as ! opposed to descending into them. ! A source code patch exists which remedies this problem. ! This is the second version of the patch.
!
! 028: SECURITY FIX: May 29, 2001 All architectures
! The signal handlers in sendmail(8) contain code that is unsafe in the ! context of a signal handler. This leads to potentially serious ! race conditions. At the moment this is a theoretical attack only ! and can only be exploited on the local host (if at all).
! A source code patch exists which remedies this problem. - It updates sendmail to version 8.11.4.
