|---|---|---|---|---|---|
| CVE-2023-38408 | 2 Fedoraproject, Openbsd | 2 Fedora, Openssh | 2023-12-22 | 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-2023-28531 | 2 Netapp, Openbsd | 4 Brocade Fabric Operating System, Hci Bootstrap Os, Solidfire Element Os and 1 more | 2023-12-22 | N/A | 9.8 CRITICAL |
| ssh-add in OpenSSH before 9.3 adds smartcard keys to ssh-agent without the intended per-hop destination constraints. The earliest affected version is 8.9. | |||||
| 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-2020-16088 | 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-2015-5334 | 2 Openbsd, Opensuse | 2 Libressl, Opensuse | 2020-01-30 | 7.5 HIGH | 9.8 CRITICAL |
| Off-by-one error in the OBJ_obj2txt function in LibreSSL before 2.3.1 allows remote attackers to cause a denial of service (program crash) or possible execute arbitrary code via a crafted X.509 certificate, which triggers a stack-based buffer overflow. Note: this vulnerability exists because of an incorrect fix for CVE-2014-3508. | |||||
| CVE-2012-1577 | 3 Debian, Dietlibc Project, Openbsd | 3 Debian Linux, Dietlibc, Openbsd | 2019-12-17 | 7.5 HIGH | 9.8 CRITICAL |
| lib/libc/stdlib/random.c in OpenBSD returns 0 when seeded with 0. | |||||
| CVE-2019-19521 | 1 Openbsd | 1 Openbsd | 2019-12-12 | 7.5 HIGH | 9.8 CRITICAL |
| libc in OpenBSD 6.6 allows authentication bypass via the -schallenge username, as demonstrated by smtpd, ldapd, or radiusd. This is related to gen/auth_subr.c and gen/authenticate.c in libc (and login/login.c and xenocara/app/xenodm/greeter/verify.c). | |||||
| CVE-2017-1000372 | 1 Openbsd | 1 Openbsd | 2019-10-03 | 7.5 HIGH | 9.8 CRITICAL |
| A flaw exists in OpenBSD's implementation of the stack guard page that allows attackers to bypass it resulting in arbitrary code execution using setuid binaries such as /usr/bin/at. This affects OpenBSD 6.1 and possibly earlier versions. | |||||
| CVE-2016-1908 | 1 Openbsd | 1 Openssh | 2018-09-11 | 7.5 HIGH | 9.8 CRITICAL |
| The client in OpenSSH before 7.2 mishandles failed cookie generation for untrusted X11 forwarding and relies on the local X11 server for access-control decisions, which allows remote X11 clients to trigger a fallback and obtain trusted X11 forwarding privileges by leveraging configuration issues on this X11 server, as demonstrated by lack of the SECURITY extension on this X11 server. | |||||
| CVE-2015-7687 | 2 Fedoraproject, Openbsd | 2 Fedora, Opensmtpd | 2017-11-01 | 7.5 HIGH | 9.8 CRITICAL |
| Use-after-free vulnerability in OpenSMTPD before 5.7.2 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via vectors involving req_ca_vrfy_smtp and req_ca_vrfy_mta. | |||||
