CVE-2008-1148 8 Apple, Cosmicperl, Darwin and 5 more 9 Mac Os X, Mac Os X Server, Directory Pro and 6 more 2025-04-09 N/A
A certain pseudo-random number generator (PRNG) algorithm that uses ADD with 0 random hops (aka "Algorithm A0"), as used in OpenBSD 3.5 through 4.2 and NetBSD 1.6.2 through 4.0, allows remote attackers to guess sensitive values such as (1) DNS transaction IDs or (2) IP fragmentation IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as DNS cache poisoning, injection into TCP packets, and OS fingerprinting.
CVE-2008-4609 12 Bsd, Bsdi, Cisco and 9 more 22 Bsd, Bsd Os, Catalyst Blade Switch 3020 and 19 more 2025-04-09 N/A
The TCP implementation in (1) Linux, (2) platforms based on BSD Unix, (3) Microsoft Windows, (4) Cisco products, and probably other operating systems allows remote attackers to cause a denial of service (connection queue exhaustion) via multiple vectors that manipulate information in the TCP state table, as demonstrated by sockstress.
CVE-2006-6164 1 Openbsd 1 Openbsd 2025-04-09 N/A
The _dl_unsetenv function in loader.c in the ELF ld.so in OpenBSD 3.9 and 4.0 does not properly remove duplicate environment variables, which allows local users to pass dangerous variables such as LD_PRELOAD to loading processes, which might be leveraged to gain privileges.
CVE-2006-4436 1 Openbsd 1 Openbsd 2025-04-03 N/A
isakmpd in OpenBSD 3.8, 3.9, and possibly earlier versions, creates Security Associations (SA) with a replay window of size 0 when isakmpd acts as a responder during SA negotiation, which allows remote attackers to replay IPSec packets and bypass the replay protection.
CVE-2002-1345 3 Ncftp Software, Openbsd, Sun 4 Ncftp, Openbsd, Solaris and 1 more 2025-04-03 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-2001-1047 1 Openbsd 1 Openbsd 2025-04-03 N/A
Race condition in OpenBSD VFS allows local users to cause a denial of service (kernel panic) by (1) creating a pipe in one thread and causing another thread to set one of the file descriptors to NULL via a close, or (2) calling dup2 on a file descriptor in one process, then setting the descriptor to NULL via a close in another process that is created via rfork.
CVE-2004-2163 1 Openbsd 1 Openbsd 2025-04-03 N/A
login_radius on OpenBSD 3.2, 3.5, and possibly other versions does not verify the shared secret in a response packet from a RADIUS server, which allows remote attackers to bypass authentication by spoofing server replies.
CVE-2000-0997 2 Netbsd, Openbsd 2 Netbsd, Openbsd 2025-04-03 N/A
Format string vulnerabilities in eeprom program in OpenBSD, NetBSD, and possibly other operating systems allows local attackers to gain root privileges.
CVE-1999-0323 4 Bsdi, Freebsd, Netbsd and 1 more 4 Bsd Os, Freebsd, Netbsd and 1 more 2025-04-03 N/A
FreeBSD mmap function allows users to modify append-only or immutable files.
CVE-2004-1799 1 Openbsd 1 Openbsd 2025-04-03 N/A
PF in certain OpenBSD versions, when stateful filtering is enabled, does not limit packets for a session to the original interface, which allows remote attackers to bypass intended packet filters via spoofed packets to other interfaces.
CVE-2000-0313 1 Openbsd 1 Openbsd 2025-04-03 N/A
Vulnerability in OpenBSD 2.6 allows a local user to change interface media configurations.
CVE-1999-0062 1 Openbsd 1 Openbsd 2025-04-03 N/A
The chpass command in OpenBSD allows a local user to gain root access through file descriptor leakage.
CVE-2005-0960 1 Openbsd 1 Openbsd 2025-04-03 N/A
Multiple vulnerabilities in the SACK functionality in (1) tcp_input.c and (2) tcp_usrreq.c OpenBSD 3.5 and 3.6 allow remote attackers to cause a denial of service (memory exhaustion or system crash).
CVE-2001-1244 7 Freebsd, Hp, Linux and 4 more 9 Freebsd, Hp-ux, Vvos and 6 more 2025-04-03 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 2025-04-03 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-2004-0416 6 Cvs, Gentoo, Openbsd and 3 more 6 Cvs, Linux, Openbsd and 3 more 2025-04-03 N/A
Double free vulnerability for the error_prog_name string in CVS 1.12.x through 1.12.8, and 1.11.x through 1.11.16, may allow remote attackers to execute arbitrary code.
CVE-2002-2180 1 Openbsd 1 Openbsd 2025-04-03 N/A
The setitimer(2) system call in OpenBSD 2.0 through 3.1 does not properly check certain arguments, which allows local users to write to kernel memory and possibly gain root privileges, possibly via an integer signedness error.
CVE-2004-0112 24 4d, Apple, Avaya and 21 more 65 Webstar, Mac Os X, Mac Os X Server and 62 more 2025-04-03 N/A
The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read.
CVE-2000-0310 1 Openbsd 1 Openbsd 2025-04-03 N/A
IP fragment assembly in OpenBSD 2.4 allows a remote attacker to cause a denial of service by sending a large number of fragmented packets.
CVE-1999-0485 1 Openbsd 1 Openbsd 2025-04-03 N/A
Remote attackers can cause a system crash through ipintr() in ipq in OpenBSD.
