CVSS v3.1 |
| Sysinstall in FreeBSD 2.2.1 and earlier, when configuring anonymous FTP, creates the ftp user without a password and with /bin/date as the shell, which could allow attackers to gain access to certain system resources. |
| time server daemon timed allows remote attackers to cause a denial of service via malformed packets. |
| 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. |
| licq before 1.0.3 allows remote attackers to execute arbitrary commands via shell metacharacters in a URL. |
| cpio on FreeBSD 2.1.0, Debian GNU/Linux 3.0, and possibly other operating systems, uses a 0 umask when creating files using the -O (archive) or -F options, which creates the files with mode 0666 and allows local users to read or overwrite those files. |
| Buffer overflow in BSD line printer daemon (in.lpd or lpd) in various BSD-based operating systems allows remote attackers to execute arbitrary code via an incomplete print job followed by a request to display the printer queue. |
| FreeBSD mmap function allows users to modify append-only or immutable files. |
| ICMP messages to broadcast addresses are allowed, allowing for a Smurf attack that can cause a denial of service. |
| KDE kppp allows local users to create a directory in an arbitrary location via the HOME environmental variable. |
| Selective Acknowledgement (SACK) in FreeBSD 5.3 and 5.4 does not properly handle an incoming selective acknowledgement when there is insufficient memory, which might allow remote attackers to cause a denial of service (infinite loop). |
| FreeBSD 4.x through 4.11 and 5.x through 5.4 allows remote attackers to modify certain TCP options via a TCP packet with the SYN flag set for an already established session. |
| A logic error in the IP fragment cache functionality in pf in FreeBSD 5.3, 5.4, and 6.0, and OpenBSD, when a 'scrub fragment crop' or 'scrub fragment drop-ovl' rule is being used, allows remote attackers to cause a denial of service (crash) via crafted packets that cause a packet fragment to be inserted twice. |
| FTP servers can allow an attacker to connect to arbitrary ports on machines other than the FTP client, aka FTP bounce. |
| The NVMe driver queue processing is vulernable to guest-induced infinite loops. |
| A missing null-termination character in the last element of an nvlist array string can lead to writing outside the allocated buffer. |
| 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. |
| 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. |
| The command ctl_persistent_reserve_out allows the caller to specify an arbitrary size which will be passed to the kernel's memory allocator. |
| The fetch(3) library uses environment variables for passing certain information, including the revocation file pathname. The environment variable name used by fetch(1) to pass the filename to the library was incorrect, in effect ignoring the option.
Fetch would still connect to a host presenting a certificate included in the revocation file passed to the --crl option. |
