CVSS v3.1 |
| NetBSD contains a use-after-free and double-free vulnerability in msg_recv_copyin() within the COMPAT_NETBSD32 compatibility layer due to a missing return statement before the cleanup label on the success path. Any local user able to execute a 32-bit binary on a 64-bit NetBSD system can trigger a kernel panic or memory corruption by calling recvmsg() with msg_iovlen between 9 and IOV_MAX, causing the kernel to access a freed iovec buffer and subsequently free the same allocation a second time. |
| NetBSD contains an information disclosure vulnerability in mm_open() within sys/dev/mm.c that allows unprivileged local users to obtain real kernel virtual addresses by opening world-accessible devices such as /dev/null or /dev/zero, which incorrectly receive the PK_KMEM process flag. Attackers can exploit this misconfigured flag to bypass the CANSEE_KPTR obfuscation mechanism and read kernel virtual addresses for sensitive kernel structures including struct proc, kauth_cred, filedesc, and vmspace via sysctl KERN_PROC queries. |
| A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period. |
| NetBSD's hdaudio(4) driver in sys/dev/hdaudio/hdaudio.c contains a missing access control vulnerability that allows unprivileged local attackers to invoke the HDAUDIO_FGRP_SETCONFIG ioctl without elevated permissions by exploiting the absence of an access check on /dev/hdaudioN device nodes. Attackers can repeatedly issue HDAUDIO_FGRP_SETCONFIG from one thread while keeping DMA and IRQs live from a second thread to trigger a use-after-free race condition in hdafg_detach() between stream_stop() and stream_disestablish(), where a latched DMA interrupt dereferences a freed callback pointer, resulting in outcomes ranging from audio-subsystem denial of service and kernel panic to potential local kernel privilege escalation. |
| The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, aka the "POODLE" issue. |
| A certain pseudo-random number generator (PRNG) algorithm that uses ADD with 0 random hops (aka "Algorithm A0"), as used in OpenBSD 3.5 through 4.2 and NetBSD 1.6.2 through 4.0, allows remote attackers to guess sensitive values such as (1) DNS transaction IDs or (2) IP fragmentation IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as DNS cache poisoning, injection into TCP packets, and OS fingerprinting. |
| A certain pseudo-random number generator (PRNG) algorithm that uses XOR and 3-bit random hops (aka "Algorithm X3"), as used in OpenBSD 2.8 through 4.2, allows remote attackers to guess sensitive values such as DNS transaction IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as DNS cache poisoning against OpenBSD's modification of BIND. |
| Stack-based buffer overflow in the command_Expand_Interpret function in command.c in ppp (aka user-ppp), as distributed in FreeBSD 6.3 and 7.0, OpenBSD 4.1 and 4.2, and the net/userppp package for NetBSD, allows local users to gain privileges via long commands containing "~" characters. |
| Multiple buffer overflows in the ISO network protocol support in the NetBSD kernel 2.0 through 4.0_BETA2, and NetBSD-current before 20070329, allow local users to execute arbitrary code via long parameters to certain functions, as demonstrated by a long sockaddr structure argument to the clnp_route function. |
| Heap-based buffer overflow in the kernel in NetBSD 3.0, certain versions of FreeBSD and OpenBSD, and possibly other BSD derived operating systems allows local users to have an unknown impact. NOTE: this information is based upon a vague pre-advisory with no actionable information. Details will be updated after 20070329. |
| The NetBSD-current kernel before 20061028 does not properly perform bounds checking of an unspecified userspace parameter in the ptrace system call during a PT_DUMPCORE request, which allows local users to have an unknown impact. |
| Multiple race conditions in the (1) Sudo monitor mode and (2) Sysjail policies in Systrace on NetBSD and OpenBSD allow local users to defeat system call interposition, and consequently bypass access control policy and auditing. |
| A certain pseudo-random number generator (PRNG) algorithm that uses XOR and 2-bit random hops (aka "Algorithm X2"), as used in OpenBSD 2.6 through 3.4, Mac OS X 10 through 10.5.1, FreeBSD 4.4 through 7.0, and DragonFlyBSD 1.0 through 1.10.1, allows remote attackers to guess sensitive values such as IP fragmentation IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as injection into TCP packets and OS fingerprinting. |
| Integer overflow in banner/banner.c in FreeBSD, NetBSD, and OpenBSD might allow local users to modify memory via a long banner. NOTE: CVE and multiple third parties dispute this issue. Since banner is not setuid, an exploit would not cross privilege boundaries in normal operations. This issue is not a vulnerability |
| The IPv6 protocol allows remote attackers to cause a denial of service via crafted IPv6 type 0 route headers (IPV6_RTHDR_TYPE_0) that create network amplification between two routers. |
| Unspecified vulnerability in ptrace in NetBSD-current before 20061027, NetBSD 3.0 and 3.0.1 before 20061027, and NetBSD 2.x before 20061119 allows local users to read kernel memory and obtain sensitive information via certain manipulations of a PT_LWPINFO request, which leads to a memory leak and information leak. |
| The procfs implementation in NetBSD-current before 20061023, NetBSD 3.0 and 3.0.1 before 20061024, and NetBSD 2.x before 20061029 allows local users to cause a denial of service (kernel panic) by attempting to access /emul/linux/proc/0/stat on a procfs filesystem that was mounted with mount_procfs -o linux, which results in a NULL pointer dereference. |
| The if_clone_list function in NetBSD-current before 20061027, NetBSD 3.0 and 3.0.1 before 20061027, and NetBSD 2.x before 20061119 allows local users to read potentially sensitive, uninitialized stack memory via unspecified vectors. |
| Integer overflow in the ktruser function in NetBSD-current before 20061022, NetBSD 3 and 3-0 before 20061024, and NetBSD 2 before 20070209, when the kernel is built with the COMPAT_FREEBSD or COMPAT_DARWIN option, allows local users to cause a denial of service and possibly gain privileges. |
| The accept function in NetBSD-current before 20061023, NetBSD 3.0 and 3.0.1 before 20061024, and NetBSD 2.x before 20061029 allows local users to cause a denial of service (socket consumption) via an invalid (1) name or (2) namelen parameter, which may result in the socket never being closed (aka "a dangling socket"). |
