CVE-2002-1221 3 Freebsd, Isc, Openbsd 3 Freebsd, Bind, Openbsd 2025-04-03 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-2001-0361 2 Openbsd, Ssh 2 Openssh, Ssh 2025-04-03 N/A
Implementations of SSH version 1.5, including (1) OpenSSH up to version 2.3.0, (2) AppGate, and (3) ssh-1 up to version 1.2.31, in certain configurations, allow a remote attacker to decrypt and/or alter traffic via a "Bleichenbacher attack" on PKCS#1 version 1.5.
CVE-2003-1562 1 Openbsd 1 Openssh 2025-04-03 N/A
sshd in OpenSSH 3.6.1p2 and earlier, when PermitRootLogin is disabled and using PAM keyboard-interactive authentication, does not insert a delay after a root login attempt with the correct password, which makes it easier for remote attackers to use timing differences to determine if the password step of a multi-step authentication is successful, a different vulnerability than CVE-2003-0190.
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-2004-0175 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2025-04-03 N/A
Directory traversal vulnerability in scp for OpenSSH before 3.4p1 allows remote malicious servers to overwrite arbitrary files. NOTE: this may be a rediscovery of CVE-2000-0992.
CVE-2000-0309 1 Openbsd 1 Openbsd 2025-04-03 N/A
The i386 trace-trap handling in OpenBSD 2.4 with DDB enabled allows a local user to cause a denial of service.
CVE-2000-0751 3 Netbsd, Openbsd, Redhat 3 Netbsd, Openbsd, Linux 2025-04-03 N/A
mopd (Maintenance Operations Protocol loader daemon) does not properly cleanse user-injected format strings, which allows remote attackers to execute arbitrary commands.
CVE-2000-1208 4 Immunix, Netbsd, Openbsd and 1 more 4 Immunix, Netbsd, Openbsd and 1 more 2025-04-03 N/A
Format string vulnerability in startprinting() function of printjob.c in BSD-based lpr lpd package may allow local users to gain privileges via an improper syslog call that uses format strings from the checkremote() call.
CVE-2001-0378 1 Openbsd 1 Openbsd 2025-04-03 N/A
readline prior to 4.1, in OpenBSD 2.8 and earlier, creates history files with insecure permissions, which allows a local attacker to recover potentially sensitive information via readline history files.
CVE-2002-0640 2 Openbsd, Redhat 3 Openssh, Enterprise Linux, Linux 2025-04-03 N/A
Buffer overflow in sshd in OpenSSH 2.3.1 through 3.3 may allow remote attackers to execute arbitrary code via a large number of responses during challenge response authentication when OpenBSD is using PAM modules with interactive keyboard authentication (PAMAuthenticationViaKbdInt).
CVE-2001-0144 2 Openbsd, Ssh 2 Openssh, Ssh 2025-04-03 N/A
CORE SDI SSH1 CRC-32 compensation attack detector allows remote attackers to execute arbitrary commands on an SSH server or client via an integer overflow.
CVE-2001-0268 2 Netbsd, Openbsd 2 Netbsd, Openbsd 2025-04-03 N/A
The i386_set_ldt system call in NetBSD 1.5 and earlier, and OpenBSD 2.8 and earlier, when the USER_LDT kernel option is enabled, does not validate a call gate target, which allows local users to gain root privileges by creating a segment call gate in the Local Descriptor Table (LDT) with a target that specifies an arbitrary kernel address.
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-2023-27567 1 Openbsd 1 Openbsd 2025-03-06 7.5 High
In OpenBSD 7.2, a TCP packet with destination port 0 that matches a pf divert-to rule can crash the kernel.
CVE-2022-48437 1 Openbsd 2 Libressl, Openbsd 2025-02-10 5.3 Medium
An issue was discovered in x509/x509_verify.c in LibreSSL before 3.6.1, and in OpenBSD before 7.2 errata 001. x509_verify_ctx_add_chain does not store errors that occur during leaf certificate verification, and therefore an incorrect error is returned. This behavior occurs when there is an installed verification callback that instructs the verifier to continue upon detecting an invalid certificate.
CVE-2021-46880 1 Openbsd 2 Libressl, Openbsd 2025-02-07 9.8 Critical
x509/x509_verify.c in LibreSSL before 3.4.2, and OpenBSD before 7.0 errata 006, allows authentication bypass because an error for an unverified certificate chain is sometimes discarded.
CVE-2023-35784 1 Openbsd 2 Libressl, Openbsd 2024-12-17 9.8 Critical
A double free or use after free could occur after SSL_clear in OpenBSD 7.2 before errata 026 and 7.3 before errata 004, and in LibreSSL before 3.6.3 and 3.7.x before 3.7.3. NOTE: OpenSSL is not affected.
CVE-2024-11148 1 Openbsd 1 Openbsd 2024-12-06 7.5 High
In OpenBSD 7.4 before errata 006 and OpenBSD 7.3 before errata 020, httpd(8) is vulnerable to a NULL dereference when handling a malformed fastcgi request.
CVE-2023-52558 1 Openbsd 1 Openbsd 2024-11-21 7.5 High
In OpenBSD 7.4 before errata 002 and OpenBSD 7.3 before errata 019, a network buffer that had to be split at certain length that could crash the kernel after receiving specially crafted escape sequences.
CVE-2023-51767 3 Fedoraproject, Openbsd, Redhat 3 Fedora, Openssh, Enterprise Linux 2024-11-21 7.0 High
OpenSSH through 9.6, when common types of DRAM are used, might allow row hammer attacks (for authentication bypass) because the integer value of authenticated in mm_answer_authpassword does not resist flips of a single bit. NOTE: this is applicable to a certain threat model of attacker-victim co-location in which the attacker has user privileges.
