| CVE-2023-27567 | 1 Openbsd | 1 Openbsd | 2023-03-10 | 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-2019-14899 | 4 Apple, Freebsd, Linux and 1 more | 8 Ipados, Iphone Os, Mac Os X and 5 more | 2023-03-01 | 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-2019-16905 | 3 Netapp, Openbsd, Siemens | 7 Cloud Backup, Steelstore Cloud Integrated Storage, Openssh and 4 more | 2023-02-28 | 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-2020-15778 | 3 Broadcom, Netapp, Openbsd | 10 Fabric Operating System, A700s, A700s Firmware and 7 more | 2023-02-24 | 6.8 MEDIUM | 7.8 HIGH |
| ** DISPUTED ** scp in OpenSSH through 8.3p1 allows command injection in the scp.c toremote function, as demonstrated by backtick characters in the destination argument. NOTE: the vendor reportedly has stated that they intentionally omit validation of "anomalous argument transfers" because that could "stand a great chance of breaking existing workflows." | |||||
| CVE-2019-6110 | 4 Netapp, Openbsd, Siemens and 1 more | 9 Element Software, Ontap Select Deploy, Storage Automation Store and 6 more | 2023-02-23 | 4.0 MEDIUM | 6.8 MEDIUM |
| In OpenSSH 7.9, due to accepting and displaying arbitrary stderr output from the server, a malicious server (or Man-in-The-Middle attacker) can manipulate the client output, for example to use ANSI control codes to hide additional files being transferred. | |||||
| CVE-2019-6109 | 9 Canonical, Debian, Fedoraproject and 6 more | 28 Ubuntu Linux, Debian Linux, Fedora and 25 more | 2023-02-23 | 4.0 MEDIUM | 6.8 MEDIUM |
| An issue was discovered in OpenSSH 7.9. Due to missing character encoding in the progress display, a malicious server (or Man-in-The-Middle attacker) can employ crafted object names to manipulate the client output, e.g., by using ANSI control codes to hide additional files being transferred. This affects refresh_progress_meter() in progressmeter.c. | |||||
| CVE-2018-20685 | 9 Canonical, Debian, Fujitsu and 6 more | 30 Ubuntu Linux, Debian Linux, M10-1 and 27 more | 2023-02-23 | 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-2018-15473 | 7 Canonical, Debian, Netapp and 4 more | 24 Ubuntu Linux, Debian Linux, Aff Baseboard Management Controller and 21 more | 2023-02-23 | 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-2021-41617 | 5 Fedoraproject, Netapp, Openbsd and 2 more | 14 Fedora, Active Iq Unified Manager, Aff 500f and 11 more | 2023-02-14 | 4.4 MEDIUM | 7.0 HIGH |
| sshd in OpenSSH 6.2 through 8.x before 8.8, when certain non-default configurations are used, allows privilege escalation because supplemental groups are not initialized as expected. Helper programs for AuthorizedKeysCommand and AuthorizedPrincipalsCommand may run with privileges associated with group memberships of the sshd process, if the configuration specifies running the command as a different user. | |||||
| CVE-2012-0814 | 1 Openbsd | 1 Openssh | 2023-02-12 | 3.5 LOW | N/A |
| The auth_parse_options function in auth-options.c in sshd in OpenSSH before 5.7 provides debug messages containing authorized_keys command options, which allows remote authenticated users to obtain potentially sensitive information by reading these messages, as demonstrated by the shared user account required by Gitolite. NOTE: this can cross privilege boundaries because a user account may intentionally have no shell or filesystem access, and therefore may have no supported way to read an authorized_keys file in its own home directory. | |||||
| CVE-2008-3831 | 3 Debian, Linux, Openbsd | 3 Linux, Linux Kernel, Linux | 2023-02-12 | 4.7 MEDIUM | N/A |
| The i915 driver in (1) drivers/char/drm/i915_dma.c in the Linux kernel 2.6.24 on Debian GNU/Linux and (2) sys/dev/pci/drm/i915_drv.c in OpenBSD does not restrict the DRM_I915_HWS_ADDR ioctl to the Direct Rendering Manager (DRM) master, which allows local users to cause a denial of service (memory corruption) via a crafted ioctl call, related to absence of the DRM_MASTER and DRM_ROOT_ONLY flags in the ioctl's configuration. | |||||
| CVE-2011-1013 | 2 Linux, Openbsd | 2 Linux Kernel, Openbsd | 2023-02-12 | 7.2 HIGH | N/A |
| Integer signedness error in the drm_modeset_ctl function in (1) drivers/gpu/drm/drm_irq.c in the Direct Rendering Manager (DRM) subsystem in the Linux kernel before 2.6.38 and (2) sys/dev/pci/drm/drm_irq.c in the kernel in OpenBSD before 4.9 allows local users to trigger out-of-bounds write operations, and consequently cause a denial of service (system crash) or possibly have unspecified other impact, via a crafted num_crtcs (aka vb_num) structure member in an ioctl argument. | |||||
| CVE-2014-1692 | 1 Openbsd | 1 Openssh | 2023-02-12 | 7.5 HIGH | N/A |
| The hash_buffer function in schnorr.c in OpenSSH through 6.4, when Makefile.inc is modified to enable the J-PAKE protocol, does not initialize certain data structures, which might allow remote attackers to cause a denial of service (memory corruption) or have unspecified other impact via vectors that trigger an error condition. | |||||
| CVE-2019-19726 | 1 Openbsd | 1 Openbsd | 2023-01-30 | 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-2004-0687 | 4 Openbsd, Suse, X.org and 1 more | 4 Openbsd, Suse Linux, X11r6 and 1 more | 2023-01-20 | 7.5 HIGH | N/A |
| Multiple stack-based buffer overflows in (1) xpmParseColors in parse.c, (2) ParseAndPutPixels in create.c, and (3) ParsePixels in parse.c for libXpm before 6.8.1 allow remote attackers to execute arbitrary code via a malformed XPM image file. | |||||
| CVE-2008-4609 | 12 Bsd, Bsdi, Cisco and 9 more | 22 Bsd, Bsd Os, Catalyst Blade Switch 3020 and 19 more | 2022-12-14 | 7.1 HIGH | N/A |
| The TCP implementation in (1) Linux, (2) platforms based on BSD Unix, (3) Microsoft Windows, (4) Cisco products, and probably other operating systems allows remote attackers to cause a denial of service (connection queue exhaustion) via multiple vectors that manipulate information in the TCP state table, as demonstrated by sockstress. | |||||
| CVE-2016-0778 | 5 Apple, Hp, Openbsd and 2 more | 6 Mac Os X, Virtual Customer Access System, Openssh and 3 more | 2022-12-13 | 4.6 MEDIUM | 8.1 HIGH |
| The (1) roaming_read and (2) roaming_write functions in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2, when certain proxy and forward options are enabled, do not properly maintain connection file descriptors, which allows remote servers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact by requesting many forwardings. | |||||
| CVE-2016-1907 | 1 Openbsd | 1 Openssh | 2022-12-13 | 5.0 MEDIUM | 5.3 MEDIUM |
| The ssh_packet_read_poll2 function in packet.c in OpenSSH before 7.1p2 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via crafted network traffic. | |||||
| CVE-2016-10010 | 1 Openbsd | 1 Openssh | 2022-12-13 | 6.9 MEDIUM | 7.0 HIGH |
| sshd in OpenSSH before 7.4, when privilege separation is not used, creates forwarded Unix-domain sockets as root, which might allow local users to gain privileges via unspecified vectors, related to serverloop.c. | |||||
| CVE-2017-15906 | 5 Debian, Netapp, Openbsd and 2 more | 22 Debian Linux, Active Iq Unified Manager, Cloud Backup and 19 more | 2022-12-13 | 5.0 MEDIUM | 5.3 MEDIUM |
| The process_open function in sftp-server.c in OpenSSH before 7.6 does not properly prevent write operations in readonly mode, which allows attackers to create zero-length files. | |||||
