CVE-2002-0574 1 Freebsd 1 Freebsd 2024-11-20 5.0 MEDIUM N/A
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.
CVE-2002-0572 3 Freebsd, Openbsd, Sun 4 Freebsd, Openbsd, Solaris and 1 more 2024-11-20 7.2 HIGH N/A
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.
CVE-2002-0518 1 Freebsd 1 Freebsd 2024-11-20 5.0 MEDIUM N/A
The SYN cache (syncache) and SYN cookie (syncookie) mechanism in FreeBSD 4.5 and earlier allows remote attackers to cause a denial of service (crash) (1) via a SYN packet that is accepted using syncookies that causes a null pointer to be referenced for the socket's TCP options, or (2) by killing and restarting a process that listens on the same socket, which does not properly clear the old inpcb pointer on restart.
CVE-2002-0414 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2024-11-20 7.5 HIGH N/A
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.
CVE-2002-0391 4 Freebsd, Microsoft, Openbsd and 1 more 7 Freebsd, Windows 2000, Windows Nt and 4 more 2024-11-20 10.0 HIGH 9.8 CRITICAL
Integer overflow in xdr_array function in RPC servers for operating systems that use libc, glibc, or other code based on SunRPC including dietlibc, allows remote attackers to execute arbitrary code by passing a large number of arguments to xdr_array through RPC services such as rpc.cmsd and dmispd.
CVE-2002-0381 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2024-11-20 5.0 MEDIUM N/A
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.
CVE-2002-0062 5 Debian, Freebsd, Gnu and 2 more 5 Debian Linux, Freebsd, Ncurses and 2 more 2024-11-20 7.2 HIGH N/A
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."
CVE-2002-0004 8 Caldera, Debian, Freebsd and 5 more 9 Openlinux Server, Openlinux Workstation, Debian Linux and 6 more 2024-11-20 7.2 HIGH N/A
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.
CVE-2001-1244 7 Freebsd, Hp, Linux and 4 more 9 Freebsd, Hp-ux, Vvos and 6 more 2024-11-20 5.0 MEDIUM N/A
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.
CVE-2001-1185 1 Freebsd 1 Freebsd 2024-11-20 6.2 MEDIUM N/A
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.
CVE-2001-1180 1 Freebsd 1 Freebsd 2024-11-20 7.2 HIGH N/A
FreeBSD 4.3 does not properly clear shared signal handlers when executing a process, which allows local users to gain privileges by calling rfork with a shared signal handler, having the child process execute a setuid program, and sending a signal to the child.
CVE-2001-1166 1 Freebsd 1 Freebsd 2024-11-20 5.0 MEDIUM N/A
linprocfs on FreeBSD 4.3 and earlier does not properly restrict access to kernel memory, which allows one process with debugging rights on a privileged process to read restricted memory from that process.
CVE-2001-1155 1 Freebsd 1 Freebsd 2024-11-20 7.5 HIGH 9.8 CRITICAL
TCP Wrappers (tcp_wrappers) in FreeBSD 4.1.1 through 4.3 with the PARANOID ACL option enabled does not properly check the result of a reverse DNS lookup, which could allow remote attackers to bypass intended access restrictions via DNS spoofing.
CVE-2001-1145 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2024-11-20 6.2 MEDIUM N/A
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.
CVE-2001-1034 1 Freebsd 1 Freebsd 2024-11-20 7.2 HIGH N/A
Format string vulnerability in Hylafax on FreeBSD allows local users to execute arbitrary code via format specifiers in the -h hostname argument for (1) faxrm or (2) faxalter.
CVE-2001-1029 2 Freebsd, Openbsd 2 Freebsd, Openssh 2024-11-20 2.1 LOW N/A
libutil in OpenSSH on FreeBSD 4.4 and earlier does not drop privileges before verifying the capabilities for reading the copyright and welcome files, which allows local users to bypass the capabilities checks and read arbitrary files by specifying alternate copyright or welcome files.
CVE-2001-1017 1 Freebsd 1 Freebsd 2024-11-20 7.2 HIGH N/A
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.
CVE-2001-0969 1 Freebsd 1 Freebsd 2024-11-20 10.0 HIGH N/A
ipfw in FreeBSD does not properly handle the use of "me" in its rules when point to point interfaces are used, which causes ipfw to allow connections from arbitrary remote hosts.
CVE-2001-0796 2 Freebsd, Sgi 2 Freebsd, Irix 2024-11-20 5.0 MEDIUM N/A
SGI IRIX 6.5 through 6.5.12f and possibly earlier versions, and FreeBSD 3.0, allows remote attackers to cause a denial of service via a malformed IGMP multicast packet with a small response delay.
CVE-2001-0710 2 Freebsd, Netbsd 2 Freebsd, Netbsd 2024-11-20 5.0 MEDIUM N/A
NetBSD 1.5 and earlier and FreeBSD 4.3 and earlier allows a remote attacker to cause a denial of service by sending a large number of IP fragments to the machine, exhausting the mbuf pool.
