Background + +bhyve(8) is a hypervisor that supports running a variety of guest +operating systems in virtual machines. Newer UEFI code in Red Hat +Enterprise Linux (RHEL) 8.4 and later (as well as applicable variants) +will not boot in newly installed guests. + +II. Problem Description + +By default, NVMe data transfer operations use a scatter-gather list in +which all entries point to a fixed-size memory region. For example, if +the memory page size is 4KB, a 2MB IO requires 512 entries. Lists +themselves are also fixed in size (default is 512 entries). + +Because the list size is fixed, the last entry is special. If the IO +requires more than 512 entries, the last entry in the list contains the +address of the next list of entries. But if the IO requires exactly 512 +entries, the last entry points to data. + +The NVMe emulation missed this logic and unconditionally treated the +last entry as a pointer to the next list. + +III. Impact + +When a RHEL 8.4 and later (or variants) are installed as guests within +bhyve(8) on emulated NVMe storage, the system will not boot due to a +newer UEFI driver that is included with these distributions. + +IV.

It implements a number of device +models using the VirtIO interface to exchange data between the guest and +the host. + +II. Problem Description + +Certain VirtIO-based device models failed to handle errors when fetching +I/O descriptors. Such errors could be triggered by a malicious guest. +As a result, the device model code could be tricked into operating on +uninitialized I/O vectors, leading to memory corruption. + +III. Impact + +A malicious guest may be able to crash the bhyve process. It may be +possible to exploit the memory corruption bugs to achieve arbitrary code +execution in the bhyve process. + +IV. Workaround + +No workaround is available. Virtual machines are unaffected unless they +use one or more of the following device models: + +* virtio-console +* virtio-rnd +* virtio-scsi (available starting in FreeBSD 12.0) +* virtio-9p (available starting in FreeBSD 13.0) + +V.

Background + +libfetch(3) is a multi-protocol file transfer library included with FreeBSD +and used by the fetch(1) command-line tool, pkg(8) package manager, and +others. + +II. Problem Description + +The passive mode in FTP communication allows an out of boundary read while +libfetch uses strtol to parse the relevant numbers into address bytes. It +does not check if the line ends prematurely. If it does, the for-loop +condition checks for *p == '\0' one byte too late because p++ was already +performed. + +III. Impact + +The connection buffer size can be controlled by a malicious FTP server +because the size is increased until a newline is encountered (or no more +characters are read). This also allows to move the buffer into more +interesting areas within the address space, potentially parsing relevant +numbers for the attacker. Since these bytes become available to the server +in form of a new TCP connection to a constructed port number or even part of +the IPv6 address this is a potential information leak. + +IV.
