CVSS v3.1 |
| kernfs_xread in kernfs_vnops.c in NetBSD before 20050831 does not check for a negative offset when reading the message buffer, which allows local users to read arbitrary kernel memory. |
| NetBSD 2.0 before 2.0.4, 2.1 before 2.1.1, and 3, when the kernel is compiled with "options DIAGNOSTIC," allows local users to cause a denial of service (kernel assertion panic) via a negative linger time in the SO_LINGER socket option. |
| 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. |
| Multiple TCP implementations could allow remote attackers to cause a denial of service (bandwidth and CPU exhaustion) by setting the maximum segment size (MSS) to a very small number and requesting large amounts of data, which generates more packets with less TCP-level data that amplify network traffic and consume more server CPU to process. |
| 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. |
| Multiple ethernet Network Interface Card (NIC) device drivers do not pad frames with null bytes, which allows remote attackers to obtain information from previous packets or kernel memory by using malformed packets, as demonstrated by Etherleak. |
| NetBSD 2.0 before 20050316 and NetBSD-current before 20050112 allow local users to cause a denial of service (infinite loop and system hang) by calling the F_CLOSEM fcntl with a parameter value of 0. |
| mmap function in BSD allows local attackers in the kmem group to modify memory through devices. |
| 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, NetBSD 2.0 through 2.1, and NetBSD-current before 20051031 allows local users to gain privileges by attaching a debugger to a setuid/setgid (P_SUGID) process that performs an exec without a reset of real credentials. |
| Teardrop IP denial of service. |
| Local users can perform a denial of service in NetBSD 1.3.3 and earlier versions by creating an unusual symbolic link with the ln command, triggering a bug in VFS. |
| TCP, when using a large Window Size, makes it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP. |
| A flaw exists in NetBSD's implementation of the stack guard page that allows attackers to bypass it resulting in arbitrary code execution using certain setuid binaries. This affects NetBSD 7.1 and possibly earlier versions. |
| NetBSD maps the run-time link-editor ld.so directly below the stack region, even if ASLR is enabled, this allows attackers to more easily manipulate memory leading to arbitrary code execution. This affects NetBSD 7.1 and possibly earlier versions. |
| The NetBSD qsort() function is recursive, and not randomized, an attacker can construct a pathological input array of N elements that causes qsort() to deterministically recurse N/4 times. This allows attackers to consume arbitrary amounts of stack memory and manipulate stack memory to assist in arbitrary code execution attacks. This affects NetBSD 7.1 and possibly earlier versions. |
| mail.local in NetBSD versions 6.0 through 6.0.6, 6.1 through 6.1.5, and 7.0 allows local users to change ownership of or append data to arbitrary files on the target system via a symlink attack on the user mailbox. |
| CGI handling flaw in bozohttpd in NetBSD 6.0 through 6.0.6, 6.1 through 6.1.5, and 7.0 allows remote attackers to execute arbitrary code via crafted arguments, which are handled by a non-CGI aware program. |
| The fetch_url function in usr.bin/ftp/fetch.c in tnftp, as used in NetBSD 5.1 through 5.1.4, 5.2 through 5.2.2, 6.0 through 6.0.6, and 6.1 through 6.1.5 allows remote attackers to execute arbitrary commands via a | (pipe) character at the end of an HTTP redirect. |
| The TCP stack in 4.3BSD Net/2, as used in FreeBSD 5.4, NetBSD possibly 2.0, and OpenBSD possibly 3.6, does not properly implement the session timer, which allows remote attackers to cause a denial of service (resource consumption) via crafted packets. |
