CVSS v3.1 |
| FreeBSD, NetBSD, and OpenBSD allow an attacker to cause a denial of service by creating a large number of socket pairs using the socketpair function, setting a large buffer size via setsockopt, then writing large buffers. |
| NetBSD on a multi-homed host allows ARP packets on one network to modify ARP entries on another connected network. |
| ftpd in NetBSD 1.4.2 does not properly parse entries in /etc/ftpchroot and does not chroot the specified users, which allows those users to access other files outside of their home directory. |
| The undocumented semconfig system call in BSD freezes the state of semaphores, which allows local users to cause a denial of service of the semaphore system by using the semconfig call. |
| The BSD profil system call allows a local user to modify the internal data space of a program via profiling and execve. |
| FreeBSD mmap function allows users to modify append-only or immutable files. |
| NetBSD 1.4.2 and earlier allows local users to cause a denial of service by repeatedly running certain system calls in the kernel which do not yield the CPU, aka "cpu-hog". |
| Buffer overflow in trek on NetBSD 1.5 through 1.5.3 allows local users to gain privileges via long keyboard input. |
| The SVR4 /dev/wabi special device file in NetBSD 1.3.3 and earlier allows a local user to read or write arbitrary files on the disk associated with that device. |
| mmap function in BSD allows local attackers in the kmem group to modify memory through devices. |
| Buffer overflow in (1) mrinfo, (2) mtrace, and (3) pppd in NetBSD 1.4.x through 1.6 allows local users to gain privileges by executing the programs after filling the file descriptor tables, which produces file descriptors larger than FD_SETSIZE, which are not checked by FD_SET(). |
| tip on multiple BSD-based operating systems allows local users to cause a denial of service (execution prevention) by using flock() to lock the /var/log/acculog file. |
| 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. |
| Buffer overflow in tryelf() in readelf.c of the file command allows attackers to execute arbitrary code as the user running file, possibly via a large entity size value in an ELF header (elfhdr.e_shentsize). |
| Off-by-one error in the fb_realpath() function, as derived from the realpath function in BSD, may allow attackers to execute arbitrary code, as demonstrated in wu-ftpd 2.5.0 through 2.6.2 via commands that cause pathnames of length MAXPATHLEN+1 to trigger a buffer overflow, including (1) STOR, (2) RETR, (3) APPE, (4) DELE, (5) MKD, (6) RMD, (7) STOU, or (8) RNTO. |
| The iBCS2 system call translator for statfs in NetBSD 1.5 through 1.5.3 and FreeBSD 4 up to 4.8-RELEASE-p2 and 5 up to 5.1-RELEASE-p1 allows local users to read portions of kernel memory (memory disclosure) via a large length parameter, which copies additional kernel memory into userland memory. |
| The shmat system call in the System V Shared Memory interface for FreeBSD 5.2 and earlier, NetBSD 1.3 and earlier, and OpenBSD 2.6 and earlier, does not properly decrement a shared memory segment's reference count when the vm_map_find function fails, which could allow local users to gain read or write access to a portion of kernel memory and gain privileges. |
| OpenBSD 3.4 and NetBSD 1.6 and 1.6.1 allow remote attackers to cause a denial of service (crash) by sending an IPv6 packet with a small MTU to a listening port and then issuing a TCP connect to that port. |
| Multiple syscalls in the compat subsystem for NetBSD before 2.0 allow local users to cause a denial of service (kernel crash) via a large signal number to (1) xxx_sys_kill, (2) xxx_sys_sigaction, and possibly other translation functions. |
| NetBSD 1.4 through 1.6 beta allows local users to cause a denial of service (kernel panic) via a series of calls to the TIOCSCTTY ioctl, which causes an integer overflow in a structure counter and sets the counter to zero, which frees memory that is still in use by other processes. |
