| CVE-2007-1365 | 1 Openbsd | 1 Openbsd | 2025-04-09 | 10.0 HIGH | N/A |
| Buffer overflow in kern/uipc_mbuf2.c in OpenBSD 3.9 and 4.0 allows remote attackers to execute arbitrary code via fragmented IPv6 packets due to "incorrect mbuf handling for ICMP6 packets." NOTE: this was originally reported as a denial of service. | |||||
| CVE-2008-1215 | 3 Freebsd, Netbsd, Openbsd | 3 Freebsd, Netbsd, Openbsd | 2025-04-09 | 4.6 MEDIUM | N/A |
| Stack-based buffer overflow in the command_Expand_Interpret function in command.c in ppp (aka user-ppp), as distributed in FreeBSD 6.3 and 7.0, OpenBSD 4.1 and 4.2, and the net/userppp package for NetBSD, allows local users to gain privileges via long commands containing "~" characters. | |||||
| CVE-2009-3572 | 1 Openbsd | 1 Openbsd | 2025-04-09 | 4.9 MEDIUM | N/A |
| OpenBSD 4.4, 4.5, and 4.6, when running on an i386 kernel, does not properly handle XMM exceptions, which allows local users to cause a denial of service (kernel panic) via unspecified vectors. | |||||
| CVE-2008-1483 | 1 Openbsd | 1 Openssh | 2025-04-09 | 6.9 MEDIUM | N/A |
| OpenSSH 4.3p2, and probably other versions, allows local users to hijack forwarded X connections by causing ssh to set DISPLAY to :10, even when another process is listening on the associated port, as demonstrated by opening TCP port 6010 (IPv4) and sniffing a cookie sent by Emacs. | |||||
| CVE-2006-5051 | 3 Apple, Debian, Openbsd | 4 Mac Os X, Mac Os X Server, Debian Linux and 1 more | 2025-04-09 | 9.3 HIGH | 8.1 HIGH |
| Signal handler race condition in OpenSSH before 4.4 allows remote attackers to cause a denial of service (crash), and possibly execute arbitrary code if GSSAPI authentication is enabled, via unspecified vectors that lead to a double-free. | |||||
| CVE-2008-5161 | 2 Openbsd, Ssh | 5 Openssh, Tectia Client, Tectia Connector and 2 more | 2025-04-09 | 2.6 LOW | N/A |
| Error handling in the SSH protocol in (1) SSH Tectia Client and Server and Connector 4.0 through 4.4.11, 5.0 through 5.2.4, and 5.3 through 5.3.8; Client and Server and ConnectSecure 6.0 through 6.0.4; Server for Linux on IBM System z 6.0.4; Server for IBM z/OS 5.5.1 and earlier, 6.0.0, and 6.0.1; and Client 4.0-J through 4.3.3-J and 4.0-K through 4.3.10-K; and (2) OpenSSH 4.7p1 and possibly other versions, when using a block cipher algorithm in Cipher Block Chaining (CBC) mode, makes it easier for remote attackers to recover certain plaintext data from an arbitrary block of ciphertext in an SSH session via unknown vectors. | |||||
| CVE-2007-1351 | 7 Mandrakesoft, Openbsd, Redhat and 4 more | 11 Mandrake Linux, Mandrake Linux Corporate Server, Mandrake Multi Network Firewall and 8 more | 2025-04-09 | 8.5 HIGH | N/A |
| Integer overflow in the bdfReadCharacters function in bdfread.c in (1) X.Org libXfont before 20070403 and (2) freetype 2.3.2 and earlier allows remote authenticated users to execute arbitrary code via crafted BDF fonts, which result in a heap overflow. | |||||
| CVE-2007-5365 | 5 Debian, Openbsd, Redhat and 2 more | 7 Debian Linux, Openbsd, Enterprise Linux and 4 more | 2025-04-09 | 7.2 HIGH | N/A |
| Stack-based buffer overflow in the cons_options function in options.c in dhcpd in OpenBSD 4.0 through 4.2, and some other dhcpd implementations based on ISC dhcp-2, allows remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a DHCP request specifying a maximum message size smaller than the minimum IP MTU. | |||||
| CVE-2006-6730 | 2 Netbsd, Openbsd | 2 Netbsd, Openbsd | 2025-04-09 | 6.6 MEDIUM | N/A |
| OpenBSD and NetBSD permit usermode code to kill the display server and write to the X.Org /dev/xf86 device, which allows local users with root privileges to reduce securelevel by replacing the System Management Mode (SMM) handler via a write to an SMRAM address within /dev/xf86 (aka the video card memory-mapped I/O range), and then launching the new handler via a System Management Interrupt (SMI), as demonstrated by a write to Programmed I/O port 0xB2. | |||||
| CVE-2020-7247 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2025-04-03 | 10.0 HIGH | 9.8 CRITICAL |
| smtp_mailaddr in smtp_session.c in OpenSMTPD 6.6, as used in OpenBSD 6.6 and other products, allows remote attackers to execute arbitrary commands as root via a crafted SMTP session, as demonstrated by shell metacharacters in a MAIL FROM field. This affects the "uncommented" default configuration. The issue exists because of an incorrect return value upon failure of input validation. | |||||
| CVE-2001-1559 | 1 Openbsd | 1 Openbsd | 2025-04-03 | 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-2003-0955 | 1 Openbsd | 1 Openbsd | 2025-04-03 | 4.6 MEDIUM | N/A |
| OpenBSD kernel 3.3 and 3.4 allows local users to cause a denial of service (kernel panic) and possibly execute arbitrary code in 3.4 via a program with an invalid header that is not properly handled by (1) ibcs2_exec.c in the iBCS2 emulation (compat_ibcs2) or (2) exec_elf.c, which leads to a stack-based buffer overflow. | |||||
| CVE-2002-2222 | 2 Freebsd, Openbsd | 2 Ports Collection, Openbsd | 2025-04-03 | 5.1 MEDIUM | N/A |
| isakmpd/message.c in isakmpd in FreeBSD before isakmpd-20020403_1, and in OpenBSD 3.1, allows remote attackers to cause a denial of service (crash) by sending Internet Key Exchange (IKE) payloads out of sequence. | |||||
| CVE-2002-0701 | 2 Freebsd, Openbsd | 2 Freebsd, Openbsd | 2025-04-03 | 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-2003-0682 | 1 Openbsd | 1 Openssh | 2025-04-03 | 7.5 HIGH | N/A |
| "Memory bugs" in OpenSSH 3.7.1 and earlier, with unknown impact, a different set of vulnerabilities than CVE-2003-0693 and CVE-2003-0695. | |||||
| CVE-2006-4435 | 1 Openbsd | 1 Openbsd | 2025-04-03 | 4.9 MEDIUM | N/A |
| OpenBSD 3.8, 3.9, and possibly earlier versions allows context-dependent attackers to cause a denial of service (kernel panic) by allocating more semaphores than the default. | |||||
| CVE-2001-0572 | 2 Openbsd, Ssh | 2 Openssh, Ssh | 2025-04-03 | 7.5 HIGH | N/A |
| The SSH protocols 1 and 2 (aka SSH-2) as implemented in OpenSSH and other packages have various weaknesses which can allow a remote attacker to obtain the following information via sniffing: (1) password lengths or ranges of lengths, which simplifies brute force password guessing, (2) whether RSA or DSA authentication is being used, (3) the number of authorized_keys in RSA authentication, or (4) the lengths of shell commands. | |||||
| CVE-2003-0695 | 1 Openbsd | 1 Openssh | 2025-04-03 | 7.5 HIGH | N/A |
| Multiple "buffer management errors" in OpenSSH before 3.7.1 may allow attackers to cause a denial of service or execute arbitrary code using (1) buffer_init in buffer.c, (2) buffer_free in buffer.c, or (3) a separate function in channels.c, a different vulnerability than CVE-2003-0693. | |||||
| CVE-2004-0819 | 1 Openbsd | 1 Openbsd | 2025-04-03 | 5.0 MEDIUM | N/A |
| The bridge functionality in OpenBSD 3.4 and 3.5, when running a gateway configured as a bridging firewall with the link2 option for IPSec enabled, allows remote attackers to cause a denial of service (crash) via an ICMP echo (ping) packet. | |||||
| CVE-2002-0575 | 1 Openbsd | 1 Openssh | 2025-04-03 | 7.5 HIGH | N/A |
| Buffer overflow in OpenSSH before 2.9.9, and 3.x before 3.2.1, with Kerberos/AFS support and KerberosTgtPassing or AFSTokenPassing enabled, allows remote and local authenticated users to gain privileges. | |||||
