CVE-1999-0396 | 2 Netbsd, Openbsd | 2 Netbsd, Openbsd | 2022-08-17 | 2.6 LOW | N/A |
A race condition between the select() and accept() calls in NetBSD TCP servers allows remote attackers to cause a denial of service. | |||||
CVE-1999-0303 | 4 Digital, Netbsd, Openbsd and 1 more | 5 Osf 1, Netbsd, Openbsd and 2 more | 2022-08-17 | 4.6 MEDIUM | N/A |

CVE-1999-0061 | 4 Bsdi, Freebsd, Linux and 1 more | 4 Bsd Os, Freebsd, Linux Kernel and 1 more | 2022-08-17 | 5.1 MEDIUM | N/A |
File creation and deletion, and remote execution, in the BSD line printer daemon (lpd). | |||||
CVE-2021-36368 | 2 Debian, Openbsd | 2 Debian Linux, Openssh | 2022-07-01 | 2.6 LOW | 3.7 LOW |
** DISPUTED ** An issue was discovered in OpenSSH before 8.9. If a client is using public-key authentication with agent forwarding but without -oLogLevel=verbose, and an attacker has silently modified the server to support the None authentication option, then the user cannot determine whether FIDO authentication is going to confirm that the user wishes to connect to that server, or that the user wishes to allow that server to connect to a different server on the user's behalf. NOTE: the vendor's position is "this is not an authentication bypass, since nothing is being bypassed." | |||||
CVE-2021-28041 | 4 Fedoraproject, Netapp, Openbsd and 1 more | 11 Fedora, Cloud Backup, Hci Compute Node and 8 more | 2022-05-20 | 4.6 MEDIUM | 7.1 HIGH |
ssh-agent in OpenSSH before 8.5 has a double free that may be relevant in a few less-common scenarios, such as unconstrained agent-socket access on a legacy operating system, or the forwarding of an agent to an attacker-controlled host. | |||||
CVE-2022-27882 | 1 Openbsd | 1 Openbsd | 2022-05-12 | 5.0 MEDIUM | 7.5 HIGH |
slaacd in OpenBSD 6.9 and 7.0 before 2022-03-22 has an integer signedness error and resultant heap-based buffer overflow triggerable by a crafted IPv6 router advertisement. NOTE: privilege separation and pledge can prevent exploitation. | |||||
CVE-2022-27881 | 1 Openbsd | 1 Openbsd | 2022-05-12 | 5.0 MEDIUM | 7.5 HIGH |
engine.c in slaacd in OpenBSD 6.9 and 7.0 before 2022-02-21 has a buffer overflow triggerable by an IPv6 router advertisement with more than seven nameservers. NOTE: privilege separation and pledge can prevent exploitation. | |||||
CVE-2020-7247 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2022-04-29 | 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-2020-14145 | 2 Netapp, Openbsd | 10 Active Iq Unified Manager, Aff A700s, Aff A700s Firmware and 7 more | 2022-04-28 | 4.3 MEDIUM | 5.9 MEDIUM |
The client side in OpenSSH 5.7 through 8.4 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client). NOTE: some reports state that 8.5 and 8.6 are also affected. | |||||
CVE-2016-20012 | 2 Netapp, Openbsd | 5 Clustered Data Ontap, Hci Management Node, Ontap Select Deploy Administration Utility and 2 more | 2022-04-18 | 4.3 MEDIUM | 5.3 MEDIUM |
** DISPUTED ** OpenSSH through 8.7 allows remote attackers, who have a suspicion that a certain combination of username and public key is known to an SSH server, to test whether this suspicion is correct. This occurs because a challenge is sent only when that combination could be valid for a login session. NOTE: the vendor does not recognize user enumeration as a vulnerability for this product. | |||||
CVE-2001-0554 | 9 Debian, Freebsd, Ibm and 6 more | 11 Debian Linux, Freebsd, Aix and 8 more | 2022-01-21 | 10.0 HIGH | N/A |
Buffer overflow in BSD-based telnetd telnet daemon on various operating systems allows remote attackers to execute arbitrary commands via a set of options including AYT (Are You There), which is not properly handled by the telrcv function. | |||||
CVE-2020-16088 | 1 Openbsd | 1 Openbsd | 2022-01-04 | 7.5 HIGH | 9.8 CRITICAL |
iked in OpenIKED, as used in OpenBSD through 6.7, allows authentication bypass because ca.c has the wrong logic for checking whether a public key matches. | |||||
CVE-2020-26142 | 1 Openbsd | 1 Openbsd | 2021-12-03 | 2.6 LOW | 5.3 MEDIUM |
An issue was discovered in the kernel in OpenBSD 6.6. The WEP, WPA, WPA2, and WPA3 implementations treat fragmented frames as full frames. An adversary can abuse this to inject arbitrary network packets, independent of the network configuration. | |||||
CVE-2004-0079 | 23 4d, Apple, Avaya and 20 more | 66 Webstar, Mac Os X, Mac Os X Server and 63 more | 2021-11-08 | 5.0 MEDIUM | N/A |
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-2004-0081 | 23 4d, Apple, Avaya and 20 more | 66 Webstar, Mac Os X, Mac Os X Server and 63 more | 2021-11-08 | 5.0 MEDIUM | N/A |
OpenSSL 0.9.6 before 0.9.6d does not properly handle unknown message types, which allows remote attackers to cause a denial of service (infinite loop), as demonstrated using the Codenomicon TLS Test Tool. | |||||
CVE-2004-0112 | 23 4d, Apple, Avaya and 20 more | 65 Webstar, Mac Os X, Mac Os X Server and 62 more | 2021-11-08 | 5.0 MEDIUM | N/A |
The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read. | |||||
CVE-2021-41581 | 1 Openbsd | 1 Libressl | 2021-09-29 | 4.3 MEDIUM | 5.5 MEDIUM |
x509_constraints_parse_mailbox in lib/libcrypto/x509/x509_constraints.c in LibreSSL through 3.4.0 has a stack-based buffer over-read. When the input exceeds DOMAIN_PART_MAX_LEN, the buffer lacks '\0' termination. | |||||
CVE-2010-4816 | 1 Openbsd | 1 Openbsd | 2021-09-20 | 5.0 MEDIUM | 7.5 HIGH |
It was found in FreeBSD 8.0, 6.3 and 4.9, and OpenBSD 4.6 that a null pointer dereference in ftpd/popen.c may lead to remote denial of service of the ftpd service. | |||||
CVE-2016-10708 | 4 Canonical, Debian, Netapp and 1 more | 12 Ubuntu Linux, Debian Linux, Cloud Backup and 9 more | 2021-09-14 | 5.0 MEDIUM | 7.5 HIGH |
sshd in OpenSSH before 7.4 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an out-of-sequence NEWKEYS message, as demonstrated by Honggfuzz, related to kex.c and packet.c. | |||||
CVE-2019-8460 | 1 Openbsd | 1 Openbsd | 2021-08-02 | 5.0 MEDIUM | 7.5 HIGH |
OpenBSD kernel version <= 6.5 can be forced to create long chains of TCP SACK holes that causes very expensive calls to tcp_sack_option() for every incoming SACK packet which can lead to a denial of service. |
