|---|---|---|---|---|---|
| CVE-2003-0078 | 3 Freebsd, Openbsd, Openssl | 3 Freebsd, Openbsd, Openssl | 2025-04-03 | 5.0 MEDIUM | N/A |
| ssl3_get_record in s3_pkt.c for OpenSSL before 0.9.7a and 0.9.6 before 0.9.6i does not perform a MAC computation if an incorrect block cipher padding is used, which causes an information leak (timing discrepancy) that may make it easier to launch cryptographic attacks that rely on distinguishing between padding and MAC verification errors, possibly leading to extraction of the original plaintext, aka the "Vaudenay timing attack." | |||||
| CVE-1999-0724 | 1 Openbsd | 1 Openbsd | 2025-04-03 | 4.6 MEDIUM | N/A |
| Buffer overflow in OpenBSD procfs and fdescfs file systems via uio_offset in the readdir() function. | |||||
| CVE-2004-0482 | 1 Openbsd | 1 Openbsd | 2025-04-03 | 4.6 MEDIUM | N/A |
| Multiple integer overflows in (1) procfs_cmdline.c, (2) procfs_fpregs.c, (3) procfs_linux.c, (4) procfs_regs.c, (5) procfs_status.c, and (6) procfs_subr.c in procfs for OpenBSD 3.5 and earlier allow local users to read sensitive kernel memory and possibly perform other unauthorized activities. | |||||
| CVE-1999-1214 | 5 Bsd, Freebsd, Netbsd and 2 more | 5 Bsd, Freebsd, Netbsd and 2 more | 2025-04-03 | 2.1 LOW | N/A |
| The asynchronous I/O facility in 4.4 BSD kernel does not check user credentials when setting the recipient of I/O notification, which allows local users to cause a denial of service by using certain ioctl and fcntl calls to cause the signal to be sent to an arbitrary process ID. | |||||
| CVE-2000-0574 | 2 Openbsd, Washington University | 2 Ftpd, Wu-ftpd | 2025-04-03 | 5.0 MEDIUM | N/A |
| FTP servers such as OpenBSD ftpd, NetBSD ftpd, ProFTPd and Opieftpd do not properly cleanse untrusted format strings that are used in the setproctitle function (sometimes called by set_proc_title), which allows remote attackers to cause a denial of service or execute arbitrary commands. | |||||
| CVE-2000-0914 | 1 Openbsd | 1 Openbsd | 2025-04-03 | 5.0 MEDIUM | N/A |
| OpenBSD 2.6 and earlier allows remote attackers to cause a denial of service by flooding the server with ARP requests. | |||||
| CVE-2005-0740 | 1 Openbsd | 1 Openbsd | 2025-04-03 | 5.0 MEDIUM | N/A |
| The TCP stack (tcp_input.c) in OpenBSD 3.5 and 3.6 allows remote attackers to cause a denial of service (system panic) via crafted values in the TCP timestamp option, which causes invalid arguments to be used when calculating the retransmit timeout. | |||||
| CVE-2003-0190 | 3 Openbsd, Openpkg, Siemens | 6 Openssh, Openpkg, Scalance X204rna and 3 more | 2025-04-03 | 5.0 MEDIUM | N/A |
| OpenSSH-portable (OpenSSH) 3.6.1p1 and earlier with PAM support enabled immediately sends an error message when a user does not exist, which allows remote attackers to determine valid usernames via a timing attack. | |||||
| CVE-2005-0637 | 1 Openbsd | 1 Openbsd | 2025-04-03 | 5.0 MEDIUM | N/A |
| The copy functions in locore.s such as copyout in OpenBSD 3.5 and 3.6, and possibly other BSD based operating systems, may allow attackers to exceed certain address boundaries and modify kernel memory. | |||||
| CVE-2002-1420 | 1 Openbsd | 1 Openbsd | 2025-04-03 | 7.2 HIGH | N/A |
| Integer signedness error in select() on OpenBSD 3.1 and earlier allows local users to overwrite arbitrary kernel memory via a negative value for the size parameter, which satisfies the boundary check as a signed integer, but is later used as an unsigned integer during a data copying operation. | |||||
| CVE-2002-0557 | 1 Openbsd | 1 Openbsd | 2025-04-03 | 7.5 HIGH | N/A |
| Vulnerability in OpenBSD 3.0, when using YP with netgroups in the password database, causes (1) rexec or (2) rsh to run another user's shell, or (3) atrun to change to a different user's directory, possibly due to memory allocation failures or an incorrect call to auth_approval(). | |||||
| CVE-2023-27567 | 1 Openbsd | 1 Openbsd | 2025-03-06 | N/A | 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 | N/A | 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 | N/A | 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-2023-51767 | 3 Fedoraproject, Openbsd, Redhat | 3 Fedora, Openssh, Enterprise Linux | 2024-11-21 | N/A | 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. | |||||
| CVE-2023-51385 | 2 Debian, Openbsd | 2 Debian Linux, Openssh | 2024-11-21 | N/A | 6.5 MEDIUM |
| In ssh in OpenSSH before 9.6, OS command injection might occur if a user name or host name has shell metacharacters, and this name is referenced by an expansion token in certain situations. For example, an untrusted Git repository can have a submodule with shell metacharacters in a user name or host name. | |||||
| CVE-2023-51384 | 2 Debian, Openbsd | 2 Debian Linux, Openssh | 2024-11-21 | N/A | 5.5 MEDIUM |
| In ssh-agent in OpenSSH before 9.6, certain destination constraints can be incompletely applied. When destination constraints are specified during addition of PKCS#11-hosted private keys, these constraints are only applied to the first key, even if a PKCS#11 token returns multiple keys. | |||||
| CVE-2023-40216 | 1 Openbsd | 1 Openbsd | 2024-11-21 | N/A | 5.5 MEDIUM |
| OpenBSD 7.3 before errata 014 is missing an argument-count bounds check in console terminal emulation. This could cause incorrect memory access and a kernel crash after receiving crafted DCS or CSI terminal escape sequences. | |||||
| CVE-2023-38408 | 2 Fedoraproject, Openbsd | 2 Fedora, Openssh | 2024-11-21 | N/A | 9.8 CRITICAL |
| The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path, leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an incomplete fix for CVE-2016-10009. | |||||
| CVE-2023-38283 | 2 Openbgpd, Openbsd | 2 Openbgpd, Openbsd | 2024-11-21 | N/A | 5.3 MEDIUM |
| In OpenBGPD before 8.1, incorrect handling of BGP update data (length of path attributes) set by a potentially distant remote actor may cause the system to incorrectly reset a session. This is fixed in OpenBSD 7.3 errata 006. | |||||
