CVSS v3.1 |
| Buffer overflow in trek on NetBSD 1.5 through 1.5.3 allows local users to gain privileges via long keyboard input. |
| 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). |
| 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. |
| 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. |
| Multiple buffer overflows in NetBSD kernel may allow local users to execute arbitrary code and gain privileges. |
| The (1) clcs and (2) emuxki drivers in NetBSD 1.6 through 2.0.2 allow local users to cause a denial of service (kernel crash) by using the set-parameters ioctl on an audio device to change the block size and set the pause state to "unpaused" in the same ioctl, which causes a divide-by-zero error. |
| Integer overflow in the FreeBSD compatibility code (freebsd_misc.c) in NetBSD-current, NetBSD-3, NetBSD-2.0, and NetBSD-2 before 20050913; and NetBSD-1.6 before 20050914; allows local users to cause a denial of service (heap corruption or system crash) and possibly gain root privileges. |
| NetBSD 1.6 up to 3.0, when a user has "set record" in .mailrc with the default umask set, creates the record file with 0644 permissions, which allows local users to read the record file. |
| The bridge ioctl (if_bridge code) in NetBSD 1.6 through 3.0 does not clear sensitive memory before copying ioctl results to the requesting process, which allows local users to obtain portions of kernel memory. |
| The elf_load_file function in NetBSD 2.0 through 3.0 allows local users to cause a denial of service (kernel crash) via an ELF interpreter that does not have a PT_LOAD section in its header, which triggers a null dereference. |
| The kernel in NetBSD-current before September 28, 2005 allows local users to cause a denial of service (system crash) by using the SIOCGIFALIAS ioctl to gather information on a non-existent alias of a network interface, which causes a NULL pointer dereference. |
| NetBSD 1.6, 2.0, 2.1 and 3.0 allows local users to cause a denial of service (memory exhaustion) by using the sysctl system call to lock a large buffer into physical memory. |
| The ip6_savecontrol function in NetBSD 2.0 through 3.0, under certain configurations, does not check to see if IPv4-mapped sockets are being used before processing IPv6 socket options, which allows local users to cause a denial of service (crash) by creating an IPv4-mapped IPv6 socket with the SO_TIMESTAMP socket option set, then sending an IPv4 packet through the socket. |
| Operating systems with shared memory implementations based on BSD 4.4 code allow a user to conduct a denial of service and bypass memory limits (e.g., as specified with rlimits) using mmap or shmget to allocate memory and cause page faults. |
| traceroute in NetBSD 1.3.3 and Linux systems allows local users to flood other systems by providing traceroute with a large waittime (-w) option, which is not parsed properly and sets the time delay for sending packets to zero. |
| NetBSD 1.4.2 and earlier allows remote attackers to cause a denial of service by sending a packet with an unaligned IP timestamp option. |
| 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". |
| KTH Kerberos IV allows local users to change the configuration of a Kerberos server running at an elevated privilege by specifying an alternate directory using with the KRBCONFDIR environmental variable, which allows the user to gain additional privileges. |
| One-byte buffer overflow in replydirname function in BSD-based ftpd allows remote attackers to gain root privileges. |
| The i386_set_ldt system call in NetBSD 1.5 and earlier, and OpenBSD 2.8 and earlier, when the USER_LDT kernel option is enabled, does not validate a call gate target, which allows local users to gain root privileges by creating a segment call gate in the Local Descriptor Table (LDT) with a target that specifies an arbitrary kernel address. |
