CVE-2007-1365 | 1 Openbsd | 1 Openbsd | 2025-04-09 | 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-2006-5051 | 4 Apple, Debian, Openbsd and 1 more | 5 Mac Os X, Mac Os X Server, Debian Linux and 2 more | 2025-04-09 | 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-2006-4925 | 1 Openbsd | 1 Openssh | 2025-04-09 | N/A |
packet.c in ssh in OpenSSH allows remote attackers to cause a denial of service (crash) by sending an invalid protocol sequence with USERAUTH_SUCCESS before NEWKEYS, which causes newkeys[mode] to be NULL. | ||||
CVE-2006-5052 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-09 | N/A |
Unspecified vulnerability in portable OpenSSH before 4.4, when running on some platforms, allows remote attackers to determine the validity of usernames via unknown vectors involving a GSSAPI "authentication abort." | ||||
CVE-2006-4924 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-09 | N/A |
sshd in OpenSSH before 4.4, when using the version 1 SSH protocol, allows remote attackers to cause a denial of service (CPU consumption) via an SSH packet that contains duplicate blocks, which is not properly handled by the CRC compensation attack detector. | ||||
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-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-2002-0083 | 9 Conectiva, Engardelinux, Immunix and 6 more | 11 Linux, Secure Linux, Immunix and 8 more | 2025-04-03 | 9.8 Critical |
Off-by-one error in the channel code of OpenSSH 2.0 through 3.0.2 allows local users or remote malicious servers to gain privileges. | ||||
CVE-2000-0993 | 3 Freebsd, Netbsd, Openbsd | 3 Freebsd, Netbsd, Openbsd | 2025-04-03 | N/A |
Format string vulnerability in pw_error function in BSD libutil library allows local users to gain root privileges via a malformed password in commands such as chpass or passwd. | ||||
CVE-2001-1585 | 1 Openbsd | 1 Openssh | 2025-04-03 | N/A |
SSH protocol 2 (aka SSH-2) public key authentication in the development snapshot of OpenSSH 2.3.1, available from 2001-01-18 through 2001-02-08, does not perform a challenge-response step to ensure that the client has the proper private key, which allows remote attackers to bypass authentication as other users by supplying a public key from that user's authorized_keys file. | ||||
CVE-2001-1507 | 1 Openbsd | 1 Openssh | 2025-04-03 | N/A |
OpenSSH before 3.0.1 with Kerberos V enabled does not properly authenticate users, which could allow remote attackers to login unchallenged. | ||||
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-1999-1010 | 1 Openbsd | 1 Openssh | 2025-04-03 | N/A |
An SSH 1.2.27 server allows a client to use the "none" cipher, even if it is not allowed by the server policy. | ||||
CVE-2001-1459 | 1 Openbsd | 1 Openssh | 2025-04-03 | N/A |
OpenSSH 2.9 and earlier does not initiate a Pluggable Authentication Module (PAM) session if commands are executed with no pty, which allows local users to bypass resource limits (rlimits) set in pam.d. | ||||
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-2000-0962 | 1 Openbsd | 1 Openbsd | 2025-04-03 | N/A |
The IPSEC implementation in OpenBSD 2.7 does not properly handle empty AH/ESP packets, which allows remote attackers to cause a denial of service. | ||||
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-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. |
