CVSS v3.1 |
| Memory leak in FreeBSD 4.5 and earlier allows remote attackers to cause a denial of service (memory exhaustion) via ICMP echo packets that trigger a bug in ip_output() in which the reference count for a routing table entry is not decremented, which prevents the entry from being removed. |
| OpenSSL 0.9.4 and OpenSSH for FreeBSD do not properly check for the existence of the /dev/random or /dev/urandom devices, which are absent on FreeBSD Alpha systems, which causes them to produce weak keys which may be more easily broken. |
| FreeBSD 4.5 and earlier, and possibly other BSD-based operating systems, allows local users to write to or read from restricted files by closing the file descriptors 0 (standard input), 1 (standard output), or 2 (standard error), which may then be reused by a called setuid process that intended to perform I/O on normal files. |
| OpenBSD, BSDI, and other Unix operating systems allow users to set chflags and fchflags on character and block devices. |
| KAME-derived implementations of IPsec on NetBSD 1.5.2, FreeBSD 4.5, and other operating systems, does not properly consult the Security Policy Database (SPD), which could cause a Security Gateway (SG) that does not use Encapsulating Security Payload (ESP) to forward forged IPv4 packets. |
| TCP RST denial of service in FreeBSD. |
| FreeBSD, NetBSD, and OpenBSD allow an attacker to cause a denial of service by creating a large number of socket pairs using the socketpair function, setting a large buffer size via setsockopt, then writing large buffers. |
| ip_input.c in BSD-derived TCP/IP implementations allows remote attackers to cause a denial of service (crash or hang) via crafted packets. |
| Sendmail allows local users to write to a file and gain group permissions via a .forward or :include: file. |
| 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. |
| FreeBSD gdc program allows local users to modify files via a symlink attack. |
| Local users can start Sendmail in daemon mode and gain root privileges. |
| Buffer overflow and denial of service in Sendmail 8.7.5 and earlier through GECOS field gives root access to local users. |
| The suidperl and sperl program do not give up root privileges when changing UIDs back to the original users, allowing root access. |
| Buffer overflow in ncurses 5.0, and the ncurses4 compatibility package as used in Red Hat Linux, allows local users to gain privileges, related to "routines for moving the physical cursor and scrolling." |
| Buffer overflow in FreeBSD libmytinfo library allows local users to execute commands via a long TERMCAP environmental variable. |
| Multiple TCP implementations could allow remote attackers to cause a denial of service (bandwidth and CPU exhaustion) by setting the maximum segment size (MSS) to a very small number and requesting large amounts of data, which generates more packets with less TCP-level data that amplify network traffic and consume more server CPU to process. |
| Buffer overflow in FreeBSD gdc program. |
| Integer overflow in the Berkeley Fast File System (FFS) in FreeBSD 4.6.1 RELEASE-p4 and earlier allows local users to access arbitrary file contents within FFS to gain privileges by creating a file that is larger than allowed by the virtual memory system. |
| Some AIO operations in FreeBSD 4.4 may be delayed until after a call to execve, which could allow a local user to overwrite memory of the new process and gain privileges. |
