CVE-2002-1915 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2026-06-16 2.1 LOW 5.5 MEDIUM
tip on multiple BSD-based operating systems allows local users to cause a denial of service (execution prevention) by using flock() to lock the /var/log/acculog file.
CVE-2002-1420 1 Openbsd 1 Openbsd 2026-06-16 7.2 HIGH N/A
Integer signedness error in select() on OpenBSD 3.1 and earlier allows local users to overwrite arbitrary kernel memory via a negative value for the size parameter, which satisfies the boundary check as a signed integer, but is later used as an unsigned integer during a data copying operation.
CVE-2002-1345 3 Ncftp Software, Openbsd, Sun 4 Ncftp, Openbsd, Solaris and 1 more 2026-06-16 5.0 MEDIUM N/A
Directory traversal vulnerabilities in multiple FTP clients on UNIX systems allow remote malicious FTP servers to create or overwrite files as the client user via filenames containing /absolute/path or .. (dot dot) sequences.
CVE-2002-1221 3 Freebsd, Isc, Openbsd 3 Freebsd, Bind, Openbsd 2026-06-16 5.0 MEDIUM N/A
BIND 8.x through 8.3.3 allows remote attackers to cause a denial of service (crash) via SIG RR elements with invalid expiry times, which are removed from the internal BIND database and later cause a null dereference.
CVE-2002-1220 3 Freebsd, Isc, Openbsd 3 Freebsd, Bind, Openbsd 2026-06-16 5.0 MEDIUM N/A
BIND 8.3.x through 8.3.3 allows remote attackers to cause a denial of service (termination due to assertion failure) via a request for a subdomain that does not exist, with an OPT resource record with a large UDP payload size.
CVE-2002-1219 3 Freebsd, Isc, Openbsd 3 Freebsd, Bind, Openbsd 2026-06-16 7.5 HIGH N/A
Buffer overflow in named in BIND 4 versions 4.9.10 and earlier, and 8 versions 8.3.3 and earlier, allows remote attackers to execute arbitrary code via a certain DNS server response containing SIG resource records (RR).
CVE-2002-0766 1 Openbsd 1 Openbsd 2026-06-16 7.2 HIGH N/A
OpenBSD 2.9 through 3.1 allows local users to cause a denial of service (resource exhaustion) and gain root privileges by filling the kernel's file descriptor table and closing file descriptors 0, 1, or 2 before executing a privileged process, which is not properly handled when OpenBSD fails to open an alternate descriptor.
CVE-2002-0765 1 Openbsd 2 Openbsd, Openssh 2026-06-16 7.5 HIGH N/A
sshd in OpenSSH 3.2.2, when using YP with netgroups and under certain conditions, may allow users to successfully authenticate and log in with another user's password.
CVE-2002-0701 2 Freebsd, Openbsd 2 Freebsd, Openbsd 2026-06-16 2.1 LOW N/A
ktrace in BSD-based operating systems allows the owner of a process with special privileges to trace the process after its privileges have been lowered, which may allow the owner to obtain sensitive information that the process obtained while it was running with the extra privileges.
CVE-2002-0572 3 Freebsd, Openbsd, Sun 4 Freebsd, Openbsd, Solaris and 1 more 2026-06-16 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-2002-0557 1 Openbsd 1 Openbsd 2026-06-16 7.5 HIGH N/A
Vulnerability in OpenBSD 3.0, when using YP with netgroups in the password database, causes (1) rexec or (2) rsh to run another user's shell, or (3) atrun to change to a different user's directory, possibly due to memory allocation failures or an incorrect call to auth_approval().
CVE-2002-0542 1 Openbsd 1 Openbsd 2026-06-16 7.2 HIGH N/A
mail in OpenBSD 2.9 and 3.0 processes a tilde (~) escape character in a message even when it is not in interactive mode, which could allow local users to gain root privileges via calls to mail in cron.
CVE-2002-0514 1 Openbsd 1 Openbsd 2026-06-16 5.0 MEDIUM N/A
PF in OpenBSD 3.0 with the return-rst rule sets the TTL to 128 in the RST packet, which allows remote attackers to determine if a port is being filtered because the TTL is different than the default TTL.
CVE-2002-0414 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2026-06-16 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 2026-06-16 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 2026-06-16 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-2001-1559 1 Openbsd 1 Openbsd 2026-06-16 2.1 LOW 5.5 MEDIUM
The uipc system calls (uipc_syscalls.c) in OpenBSD 2.9 and 3.0 provide user mode return instead of versus rval kernel mode values to the fdrelease function, which allows local users to cause a denial of service and trigger a null dereference.
CVE-2001-1415 1 Openbsd 1 Openbsd 2026-06-16 4.6 MEDIUM N/A
vi.recover in OpenBSD before 3.1 allows local users to remove arbitrary zero-byte files such as device nodes.
CVE-2001-1244 7 Freebsd, Hp, Linux and 4 more 9 Freebsd, Hp-ux, Vvos and 6 more 2026-06-16 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-2001-1145 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2026-06-16 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.
