CVSS v3.1 |
| The implementation of SYN cookies (syncookies) in FreeBSD 4.5 through 5.0-RELEASE-p3 uses only 32-bit internal keys when generating syncookies, which makes it easier for remote attackers to conduct brute force ISN guessing attacks and spoof legitimate traffic. |
| fingerd in FreeBSD 4.1.1 allows remote attackers to read arbitrary files by specifying the target file name instead of a regular user name. |
| 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. |
| fts routines in FreeBSD 4.3 and earlier, NetBSD before 1.5.2, and OpenBSD 2.9 and earlier can be forced to change (chdir) into a different directory than intended when the directory above the current directory is moved, which could cause scripts to perform dangerous actions on the wrong directories. |
| pcnfsd (aka rpc.pcnfsd) allows local users to change file permissions, or execute arbitrary commands through arguments in the RPC call. |
| The TCP implementation in various BSD operating systems (tcp_input.c) does not properly block connections to broadcast addresses, which could allow remote attackers to bypass intended filters via packets with a unicast link layer address and an IP broadcast address. |
| The prescan function in Sendmail 8.12.9 allows remote attackers to execute arbitrary code via buffer overflow attacks, as demonstrated using the parseaddr function in parseaddr.c. |
| FreeBSD mmap function allows users to modify append-only or immutable files. |
| FreeBSD 5.1 and earlier, and Mac OS X before 10.3.4, allows remote attackers to cause a denial of service (resource exhaustion of memory buffers and system crash) via a large number of out-of-sequence TCP packets, which prevents the operating system from creating new connections. |
| rmuser utility in FreeBSD 4.2 and 4.3 creates a copy of the master.passwd file with world-readable permissions while updating the original file, which could allow local users to gain privileges by reading the copied file while rmuser is running, obtain the password hashes, and crack the passwords. |
| Buffer overflow in FreeBSD lpd through long DNS hostnames. |
| Buffer overflow and denial of service in Sendmail 8.7.5 and earlier through GECOS field gives root access to local users. |
| The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference. |
| OpenSSH on FreeBSD 5.3 and 5.4, when used with OpenPAM, does not properly handle when a forked child process terminates during PAM authentication, which allows remote attackers to cause a denial of service (client connection refusal) by connecting multiple times to the SSH server, waiting for the password prompt, then disconnecting. |
| Kerberos 5 su (k5su) in FreeBSD 4.4 and earlier relies on the getlogin system call to determine if the user running k5su is root, which could allow a root-initiated process to regain its privileges after it has dropped them. |
| ICMP messages to broadcast addresses are allowed, allowing for a Smurf attack that can cause a denial of service. |
| Sendmail decode alias can be used to overwrite sensitive files. |
| Buffer overflow in FreeBSD xmindpath allows local users to gain privileges via -f argument. |
| Heap corruption vulnerability in the "at" program allows local users to execute arbitrary code via a malformed execution time, which causes at to free the same memory twice. |
| Buffer overflow in FreeBSD seyon via HOME environmental variable, -emulator argument, -modems argument, or the GUI. |
