CVE-2020-26142 | 1 Openbsd | 1 Openbsd | 2023-12-10 | 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-2019-25048 | 2 Linux, Openbsd | 2 Linux Kernel, Libressl | 2023-12-10 | 5.8 MEDIUM | 7.1 HIGH |
LibreSSL 2.9.1 through 3.2.1 has a heap-based buffer over-read in do_print_ex (called from asn1_item_print_ctx and ASN1_item_print). | |||||
CVE-2010-4816 | 1 Openbsd | 1 Openbsd | 2023-12-10 | 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-2019-25049 | 2 Linux, Openbsd | 2 Linux Kernel, Libressl | 2023-12-10 | 5.8 MEDIUM | 7.1 HIGH |
LibreSSL 2.9.1 through 3.2.1 has an out-of-bounds read in asn1_item_print_ctx (called from asn1_template_print_ctx). | |||||
CVE-2021-28041 | 4 Fedoraproject, Netapp, Openbsd and 1 more | 11 Fedora, Cloud Backup, Hci Compute Node and 8 more | 2023-12-10 | 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-2020-14145 | 2 Netapp, Openbsd | 10 Active Iq Unified Manager, Aff A700s, Aff A700s Firmware and 7 more | 2023-12-10 | 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-2020-16088 | 1 Openbsd | 1 Openbsd | 2023-12-10 | 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-2019-19522 | 1 Openbsd | 1 Openbsd | 2023-12-10 | 7.2 HIGH | 7.8 HIGH |
OpenBSD 6.6, in a non-default configuration where S/Key or YubiKey authentication is enabled, allows local users to become root by leveraging membership in the auth group. This occurs because root's file can be written to /etc/skey or /var/db/yubikey, and need not be owned by root. | |||||
CVE-2011-3336 | 4 Apple, Freebsd, Openbsd and 1 more | 4 Mac Os X, Freebsd, Openbsd and 1 more | 2023-12-10 | 7.8 HIGH | 7.5 HIGH |
regcomp in the BSD implementation of libc is vulnerable to denial of service due to stack exhaustion. | |||||
CVE-2012-1577 | 3 Debian, Dietlibc Project, Openbsd | 3 Debian Linux, Dietlibc, Openbsd | 2023-12-10 | 7.5 HIGH | 9.8 CRITICAL |
lib/libc/stdlib/random.c in OpenBSD returns 0 when seeded with 0. | |||||
CVE-2015-5334 | 2 Openbsd, Opensuse | 2 Libressl, Opensuse | 2023-12-10 | 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-2019-16905 | 3 Netapp, Openbsd, Siemens | 7 Cloud Backup, Steelstore Cloud Integrated Storage, Openssh and 4 more | 2023-12-10 | 4.4 MEDIUM | 7.8 HIGH |
OpenSSH 7.7 through 7.9 and 8.x before 8.1, when compiled with an experimental key type, has a pre-authentication integer overflow if a client or server is configured to use a crafted XMSS key. This leads to memory corruption and local code execution because of an error in the XMSS key parsing algorithm. NOTE: the XMSS implementation is considered experimental in all released OpenSSH versions, and there is no supported way to enable it when building portable OpenSSH. | |||||
CVE-2015-5333 | 2 Openbsd, Opensuse | 2 Libressl, Opensuse | 2023-12-10 | 5.0 MEDIUM | 7.5 HIGH |
Memory leak in the OBJ_obj2txt function in LibreSSL before 2.3.1 allows remote attackers to cause a denial of service (memory consumption) via a large number of ASN.1 object identifiers in X.509 certificates. | |||||
CVE-2019-19726 | 1 Openbsd | 1 Openbsd | 2023-12-10 | 7.2 HIGH | 7.8 HIGH |
OpenBSD through 6.6 allows local users to escalate to root because a check for LD_LIBRARY_PATH in setuid programs can be defeated by setting a very small RLIMIT_DATA resource limit. When executing chpass or passwd (which are setuid root), _dl_setup_env in ld.so tries to strip LD_LIBRARY_PATH from the environment, but fails when it cannot allocate memory. Thus, the attacker is able to execute their own library code as root. | |||||
CVE-2012-5663 | 1 Openbsd | 1 Textproc\/isearch | 2023-12-10 | 5.0 MEDIUM | 7.5 HIGH |
The isearch package (textproc/isearch) before 1.47.01nb1 uses the tempnam() function to create insecure temporary files into a publicly-writable area (/tmp). | |||||
CVE-2020-7247 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2023-12-10 | 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-2019-19521 | 1 Openbsd | 1 Openbsd | 2023-12-10 | 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-2019-19519 | 1 Openbsd | 1 Openbsd | 2023-12-10 | 4.6 MEDIUM | 7.8 HIGH |
In OpenBSD 6.6, local users can use the su -L option to achieve any login class (often excluding root) because there is a logic error in the main function in su/su.c. | |||||
CVE-2019-19520 | 1 Openbsd | 1 Openbsd | 2023-12-10 | 4.6 MEDIUM | 7.8 HIGH |
xlock in OpenBSD 6.6 allows local users to gain the privileges of the auth group by providing a LIBGL_DRIVERS_PATH environment variable, because xenocara/lib/mesa/src/loader/loader.c mishandles dlopen. | |||||
CVE-2019-14899 | 4 Apple, Freebsd, Linux and 1 more | 8 Ipados, Iphone Os, Mac Os X and 5 more | 2023-12-10 | 4.9 MEDIUM | 7.4 HIGH |
A vulnerability was discovered in Linux, FreeBSD, OpenBSD, MacOS, iOS, and Android that allows a malicious access point, or an adjacent user, to determine if a connected user is using a VPN, make positive inferences about the websites they are visiting, and determine the correct sequence and acknowledgement numbers in use, allowing the bad actor to inject data into the TCP stream. This provides everything that is needed for an attacker to hijack active connections inside the VPN tunnel. |
