CVSS v3.1 |
| Buffer overflow in FreeBSD lpd through long DNS hostnames. |
| mmap function in BSD allows local attackers in the kmem group to modify memory through devices. |
| The system configuration control (sysctl) facility in BSD based operating systems OpenBSD 2.2 and earlier, and FreeBSD 2.2.5 and earlier, does not properly restrict source routed packets even when the (1) dosourceroute or (2) forwarding variables are set, which allows remote attackers to spoof TCP connections. |
| The open() function in FreeBSD allows local attackers to write to arbitrary files. |
| FreeBSD mmap function allows users to modify append-only or immutable files. |
| Jolt ICMP attack causes a denial of service in Windows 95 and Windows NT systems. |
| A buffer overflow in lsof allows local users to obtain root privilege. |
| ICMP messages to broadcast addresses are allowed, allowing for a Smurf attack that can cause a denial of service. |
| The rwho/rwhod service is running, which exposes machine status and user information. |
| OpenBSD, BSDI, and other Unix operating systems allow users to set chflags and fchflags on character and block devices. |
| ip_input.c in BSD-derived TCP/IP implementations allows remote attackers to cause a denial of service (crash or hang) via crafted packets. |
| The command ctl_persistent_reserve_out allows the caller to specify an arbitrary size which will be passed to the kernel's memory allocator. |
| In some cases, the ktrace facility will log the contents of kernel structures to userspace. In one such case, ktrace dumps a variable-sized sockaddr to userspace. There, the full sockaddr is copied, even when it is shorter than the full size. This can result in up to 14 uninitialized bytes of kernel memory being copied out to userspace.
It is possible for an unprivileged userspace program to leak 14 bytes of a kernel heap allocation to userspace. |
| When etcupdate encounters conflicts while merging files, it saves a version containing conflict markers in /var/db/etcupdate/conflicts. This version does not preserve the mode of the input file, and is world-readable. This applies to files that would normally have restricted visibility, such as /etc/master.passwd.
An unprivileged local user may be able to read encrypted root and user passwords from the temporary master.passwd file created in /var/db/etcupdate/conflicts. This is possible only when conflicts within the password file arise during an update, and the unprotected file is deleted when conflicts are resolved. |
| On 64-bit systems, the implementation of VOP_VPTOFH() in the cd9660, tarfs and ext2fs filesystems overflows the destination FID buffer by 4 bytes, a stack buffer overflow.
A NFS server that exports a cd9660, tarfs, or ext2fs file system can be made to panic by mounting and accessing the export with an NFS client. Further exploitation (e.g., bypassing file permission checking or remote kernel code execution) is potentially possible, though this has not been demonstrated. In particular, release kernels are compiled with stack protection enabled, and some instances of the overflow are caught by this mechanism, causing a panic. |
| In ICMPv6 Neighbor Discovery (ND), the ID is always 0. When pf is configured to allow ND and block incoming Echo Requests, a crafted Echo Request packet after a Neighbor Solicitation (NS) can trigger an Echo Reply. The packet has to come from the same host as the NS and have a zero as identifier to match the state created by the Neighbor Discovery and allow replies to be generated.
ICMPv6 packets with identifier value of zero bypass firewall rules written on the assumption that the incoming packets are going to create a state in the state table. |
| The NVMe driver queue processing is vulernable to guest-induced infinite loops. |
| The hda driver is vulnerable to a buffer over-read from a guest-controlled value. |
| The virtio_vq_recordon function is subject to a time-of-check to time-of-use (TOCTOU) race condition. |
| The NVMe driver function nvme_opc_get_log_page is vulnerable to a buffer over-read from a guest-controlled value. |
