FreeBSD Security Advisory - The e1000 network adapters permit a variety of modifications to an Ethernet packet when it is being transmitted. These include the insertion of IP and TCP checksums, insertion of an Ethernet VLAN header, and TCP segmentation offload ("TSO"). The e1000 device model uses an on-stack buffer to generate the modified packet header when simulating these modifications on transmitted packets. When TCP segmentation offload is requested for a transmitted packet, the e1000 device model used a guest-provided value to determine the size of the on-stack buffer without validation. The subsequent header generation could overflow an incorrectly sized buffer or indirect a pointer composed of stack garbage. A misbehaving bhyve guest could overwrite memory in the bhyve process on the host.

FreeBSD Security Advisory - Due do a missing check in the code of m_pulldown(9) data returned may not be contiguous as requested by the caller. Extra checks in the IPv6 code catch the error condition and trigger a kernel panic leading to a remote DoS (denial-of-service) attack with certain Ethernet interfaces. At this point it is unknown if any other than the IPv6 code paths can trigger a similar condition.

FreeBSD Security Advisory - The kernel driver for /dev/midistat implements a handler for read(2). This handler is not thread-safe, and a multi-threaded program can exploit races in the handler to cause it to copy out kernel memory outside the boundaries of midistat's data buffer. The races allow a program to read kernel memory within a 4GB window centered at midistat's data buffer. The buffer is allocated each time the device is opened, so an attacker is not limited to a static 4GB region of memory. On 32-bit platforms, an attempt to trigger the race may cause a page fault in kernel mode, leading to a panic.

FreeBSD Security Advisory - System calls operating on file descriptors obtain a reference to relevant struct file which due to a programming error was not always put back, which in turn could be used to overflow the counter of affected struct file. A local user can use this flaw to obtain access to files, directories, sockets, etc., opened by processes owned by other users. If obtained struct file represents a directory from outside of user's jail, it can be used to access files outside of the jail. If the user in question is a jailed root they can obtain root privileges on the host system.

FreeBSD Security Advisory - From time to time Intel releases new CPU microcode to address functional issues and security vulnerabilities. Such a release is also known as a Micro Code Update (MCU), and is a component of a broader Intel Platform Update (IPU). FreeBSD distributes CPU microcode via the devcpu-data port and package.

FreeBSD Security Advisory - Intel discovered a previously published erratum on some Intel platforms can be exploited by malicious software to potentially cause a denial of service by triggering a machine check that will crash or hang the system. Malicious guest operating systems may be able to crash the host.

FreeBSD Security Advisory - A programming error allows an attacker who can specify a URL with a username and/or password components to overflow libfetch(3) buffers. An attacker in control of the URL to be fetched (possibly via HTTP redirect) may cause a heap buffer overflow, resulting in program misbehavior or malicious code execution.

FreeBSD Security Advisory - A missing check means that an attacker can reinject an old packet and it will be accepted and processed by the IPsec endpoint. The impact depends on the higher-level protocols in use over IPsec. For example, an attacker who can capture and inject packets could cause an action that was intentionally performed once to be repeated.

FreeBSD Security Advisory - The kernel can create a core dump file when a process crashes that contains process state, for debugging. Due to incorrect initialization of a stack data structure, up to 20 bytes of kernel data stored previously stored on the stack will be exposed to a crashing user process. Sensitive kernel data may be disclosed.
