CVE-2006-5218 | 2 Netbsd, Openbsd | 2 Netbsd, Openbsd | 2025-04-09 | N/A |
Integer overflow in the systrace_preprepl function (STRIOCREPLACE) in systrace in OpenBSD 3.9 and NetBSD 3 allows local users to cause a denial of service (crash), gain privileges, or read arbitrary kernel memory via large numeric arguments to the systrace ioctl. | ||||
CVE-2007-2242 | 5 Freebsd, Ietf, Netbsd and 2 more | 5 Freebsd, Ipv6, Netbsd and 2 more | 2025-04-09 | N/A |
The IPv6 protocol allows remote attackers to cause a denial of service via crafted IPv6 type 0 route headers (IPV6_RTHDR_TYPE_0) that create network amplification between two routers. | ||||
CVE-2008-4109 | 2 Debian, Openbsd | 2 Linux, Openssh | 2025-04-09 | N/A |
A certain Debian patch for OpenSSH before 4.3p2-9etch3 on etch; before 4.6p1-1 on sid and lenny; and on other distributions such as SUSE uses functions that are not async-signal-safe in the signal handler for login timeouts, which allows remote attackers to cause a denial of service (connection slot exhaustion) via multiple login attempts. NOTE: this issue exists because of an incorrect fix for CVE-2006-5051. | ||||
CVE-2007-2243 | 1 Openbsd | 1 Openssh | 2025-04-09 | N/A |
OpenSSH 4.6 and earlier, when ChallengeResponseAuthentication is enabled, allows remote attackers to determine the existence of user accounts by attempting to authenticate via S/KEY, which displays a different response if the user account exists, a similar issue to CVE-2001-1483. | ||||
CVE-2007-3102 | 3 Fedora Project, Openbsd, Redhat | 3 Fedora Core, Openssh, Enterprise Linux | 2025-04-09 | N/A |
Unspecified vulnerability in the linux_audit_record_event function in OpenSSH 4.3p2, as used on Fedora Core 6 and possibly other systems, allows remote attackers to write arbitrary characters to an audit log via a crafted username. NOTE: some of these details are obtained from third party information. | ||||
CVE-2007-4305 | 5 Netbsd, Openbsd, Sysjail and 2 more | 5 Netbsd, Openbsd, Sysjail and 2 more | 2025-04-09 | N/A |
Multiple race conditions in the (1) Sudo monitor mode and (2) Sysjail policies in Systrace on NetBSD and OpenBSD allow local users to defeat system call interposition, and consequently bypass access control policy and auditing. | ||||
CVE-2006-6730 | 2 Netbsd, Openbsd | 2 Netbsd, Openbsd | 2025-04-09 | 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-2007-4752 | 2 Openbsd, Redhat | 3 Openssh, Enterprise Linux, Rhel Eus | 2025-04-09 | N/A |
ssh in OpenSSH before 4.7 does not properly handle when an untrusted cookie cannot be created and uses a trusted X11 cookie instead, which allows attackers to violate intended policy and gain privileges by causing an X client to be treated as trusted. | ||||
CVE-2007-5365 | 5 Debian, Openbsd, Redhat and 2 more | 7 Debian Linux, Openbsd, Enterprise Linux and 4 more | 2025-04-09 | 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-2020-7247 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2025-04-03 | 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-2001-1415 | 1 Openbsd | 1 Openbsd | 2025-04-03 | N/A |
vi.recover in OpenBSD before 3.1 allows local users to remove arbitrary zero-byte files such as device nodes. | ||||
CVE-2001-1382 | 1 Openbsd | 1 Openssh | 2025-04-03 | N/A |
The "echo simulation" traffic analysis countermeasure in OpenSSH before 2.9.9p2 sends an additional echo packet after the password and carriage return is entered, which could allow remote attackers to determine that the countermeasure is being used. | ||||
CVE-2000-0992 | 2 Openbsd, Ssh | 2 Openssh, Ssh | 2025-04-03 | N/A |
Directory traversal vulnerability in scp in sshd 1.2.xx allows a remote malicious scp server to overwrite arbitrary files via a .. (dot dot) attack. | ||||
CVE-2001-1380 | 2 Openbsd, Redhat | 2 Openssh, Linux | 2025-04-03 | N/A |
OpenSSH before 2.9.9, while using keypairs and multiple keys of different types in the ~/.ssh/authorized_keys2 file, may not properly handle the "from" option associated with a key, which could allow remote attackers to login from unauthorized IP addresses. | ||||
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-2005-0356 | 9 Alaxala, Cisco, F5 and 6 more | 76 Alaxala Networks, Agent Desktop, Aironet Ap1200 and 73 more | 2025-04-03 | N/A |
Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old. | ||||
CVE-2004-0079 | 23 4d, Apple, Avaya and 20 more | 67 Webstar, Mac Os X, Mac Os X Server and 64 more | 2025-04-03 | 7.5 High |
The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference. | ||||
CVE-2003-0955 | 1 Openbsd | 1 Openbsd | 2025-04-03 | 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-2004-1653 | 1 Openbsd | 1 Openssh | 2025-04-03 | N/A |
The default configuration for OpenSSH enables AllowTcpForwarding, which could allow remote authenticated users to perform a port bounce, when configured with an anonymous access program such as AnonCVS. | ||||
CVE-2004-1471 | 6 Cvs, Freebsd, Gentoo and 3 more | 6 Cvs, Freebsd, Linux and 3 more | 2025-04-03 | N/A |
Format string vulnerability in wrapper.c in CVS 1.12.x through 1.12.8, and 1.11.x through 1.11.16 allows remote attackers with CVSROOT commit access to cause a denial of service (application crash) and possibly execute arbitrary code via format string specifiers in a wrapper line. |
