| CVE-2019-25049 | 2 Linux, Openbsd | 2 Linux Kernel, Libressl | 2024-11-21 | 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-2019-25048 | 2 Linux, Openbsd | 2 Linux Kernel, Libressl | 2024-11-21 | 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-2019-19726 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 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-2019-19522 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 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-2019-19521 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 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-2019-19520 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 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-2019-19519 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 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-2019-14899 | 4 Apple, Freebsd, Linux and 1 more | 8 Ipados, Iphone Os, Mac Os X and 5 more | 2024-11-21 | 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. | |||||
| CVE-2018-8970 | 1 Openbsd | 1 Libressl | 2024-11-21 | 5.8 MEDIUM | 7.4 HIGH |
| The int_x509_param_set_hosts function in lib/libcrypto/x509/x509_vpm.c in LibreSSL 2.7.0 before 2.7.1 does not support a certain special case of a zero name length, which causes silent omission of hostname verification, and consequently allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate. NOTE: the LibreSSL documentation indicates that this special case is supported, but the BoringSSL documentation does not. | |||||
| CVE-2018-20685 | 9 Canonical, Debian, Fujitsu and 6 more | 30 Ubuntu Linux, Debian Linux, M10-1 and 27 more | 2024-11-21 | 2.6 LOW | 5.3 MEDIUM |
| In OpenSSH 7.9, scp.c in the scp client allows remote SSH servers to bypass intended access restrictions via the filename of . or an empty filename. The impact is modifying the permissions of the target directory on the client side. | |||||
| CVE-2018-15919 | 2 Netapp, Openbsd | 7 Cloud Backup, Cn1610, Cn1610 Firmware and 4 more | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| Remotely observable behaviour in auth-gss2.c in OpenSSH through 7.8 could be used by remote attackers to detect existence of users on a target system when GSS2 is in use. NOTE: the discoverer states 'We understand that the OpenSSH developers do not want to treat such a username enumeration (or "oracle") as a vulnerability.' | |||||
| CVE-2018-15473 | 7 Canonical, Debian, Netapp and 4 more | 24 Ubuntu Linux, Debian Linux, Aff Baseboard Management Controller and 21 more | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| OpenSSH through 7.7 is prone to a user enumeration vulnerability due to not delaying bailout for an invalid authenticating user until after the packet containing the request has been fully parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c. | |||||
| CVE-2018-14775 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 4.9 MEDIUM | 5.5 MEDIUM |
| tss_alloc in sys/arch/i386/i386/gdt.c in OpenBSD 6.2 and 6.3 has a Local Denial of Service (system crash) due to incorrect I/O port access control on the i386 architecture. | |||||
| CVE-2018-12434 | 1 Openbsd | 1 Libressl | 2024-11-21 | 1.9 LOW | 4.7 MEDIUM |
| LibreSSL before 2.6.5 and 2.7.x before 2.7.4 allows a memory-cache side-channel attack on DSA and ECDSA signatures, aka the Return Of the Hidden Number Problem or ROHNP. To discover a key, the attacker needs access to either the local machine or a different virtual machine on the same physical host. | |||||
| CVE-2016-20012 | 2 Netapp, Openbsd | 5 Clustered Data Ontap, Hci Management Node, Ontap Select Deploy Administration Utility and 2 more | 2024-11-21 | 4.3 MEDIUM | 5.3 MEDIUM |
| 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-2016-10708 | 4 Canonical, Debian, Netapp and 1 more | 12 Ubuntu Linux, Debian Linux, Cloud Backup and 9 more | 2024-11-21 | 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-2015-5334 | 2 Openbsd, Opensuse | 2 Libressl, Opensuse | 2024-11-21 | 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-2015-5333 | 2 Openbsd, Opensuse | 2 Libressl, Opensuse | 2024-11-21 | 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-2012-5663 | 1 Openbsd | 1 Textproc\/isearch | 2024-11-21 | 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-2012-1577 | 3 Debian, Dietlibc Project, Openbsd | 3 Debian Linux, Dietlibc, Openbsd | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| lib/libc/stdlib/random.c in OpenBSD returns 0 when seeded with 0. | |||||
