CVSS v3.1 |
| FTP servers can allow an attacker to connect to arbitrary ports on machines other than the FTP client, aka FTP bounce. |
| FreeBSD kernel 5.4-STABLE and 6.0 does not completely initialize a buffer before making it available to userland, which could allow local users to read portions of kernel memory. |
| A logic error in FreeBSD kernel 5.4-STABLE and 6.0 causes the kernel to calculate an incorrect buffer length, which causes more data to be copied to userland than intended, which could allow local users to read portions of kernel memory. |
| Local user gains root privileges via buffer overflow in rdist, via expstr() function. |
| Sendmail decode alias can be used to overwrite sensitive files. |
| The asynchronous I/O facility in 4.4 BSD kernel does not check user credentials when setting the recipient of I/O notification, which allows local users to cause a denial of service by using certain ioctl and fcntl calls to cause the signal to be sent to an arbitrary process ID. |
| Vulnerability in union file system in FreeBSD 2.2 and earlier, and possibly other operating systems, allows local users to cause a denial of service (system reload) via a series of certain mount_union commands. |
| Buffer overflow in ppp program in FreeBSD 2.1 and earlier allows local users to gain privileges via a long HOME environment variable. |
| libedit searches for the .editrc file in the current directory instead of the user's home directory, which may allow local users to execute arbitrary commands by installing a modified .editrc in another directory. |
| IP fragmentation denial of service in FreeBSD allows a remote attacker to cause a crash. |
| 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. |
| KDE klock allows local users to kill arbitrary processes by specifying an arbitrary PID in the .kss.pid file. |
| A missing null-termination character in the last element of an nvlist array string can lead to writing outside the allocated buffer. |
| Malicious software running in a guest VM can exploit the buffer overflow to achieve code execution on the host in the bhyve userspace process, which typically runs as root. Note that bhyve runs in a Capsicum sandbox, so malicious code is constrained by the capabilities available to the bhyve process. |
| An insufficient boundary validation in the USB code could lead to an out-of-bounds read on the heap, which could potentially lead to an arbitrary write and remote code execution. |
| 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 function nvme_opc_get_log_page is vulnerable to a buffer over-read from a guest-controlled value. |
