Openbsd: >> Openbsd >> 2.9 Security Vulnerabilities
Race condition in exec in OpenBSD 4.0 and earlier, NetBSD 1.5.2 and earlier, and FreeBSD 4.4 and earlier allows local users to gain privileges by attaching a debugger to a process before the kernel has determined that the process is setuid or setgid.

The setitimer(2) system call in OpenBSD 2.0 through 3.1 does not properly check certain arguments, which allows local users to write to kernel memory and possibly gain root privileges, possibly via an integer signedness error.

syslogd on OpenBSD 2.9 through 3.2 does not change the source IP address of syslog packets when the machine's IP addressed is changed without rebooting, e.g. via ifconfig, which can cause incorrect information to be sent to the syslog server.

OpenBSD 2.9 through 3.1 allows local users to cause a denial of service (resource exhaustion) and gain root privileges by filling the kernel's file descriptor table and closing file descriptors 0, 1, or 2 before executing a privileged process, which is not properly handled when OpenBSD fails to open an alternate descriptor.

ktrace in BSD-based operating systems allows the owner of a process with special privileges to trace the process after its privileges have been lowered, which may allow the owner to obtain sensitive information that the process obtained while it was running with the extra privileges.

mail in OpenBSD 2.9 and 3.0 processes a tilde (~) escape character in a message even when it is not in interactive mode, which could allow local users to gain root privileges via calls to mail in cron.

The TCP implementation in various BSD operating systems (tcp_input.c) does not properly block connections to broadcast addresses, which could allow remote attackers to bypass intended filters via packets with a unicast link layer address and an IP broadcast address.

The uipc system calls (uipc_syscalls.c) in OpenBSD 2.9 and 3.0 provide user mode return instead of versus rval kernel mode values to the fdrelease function, which allows local users to cause a denial of service and trigger a null dereference.
