| CVE-2014-7250 | 4 Bsd, Freebsd, Netbsd and 1 more | 4 Bsd, Freebsd, Netbsd and 1 more | 2025-04-12 | N/A |
| The TCP stack in 4.3BSD Net/2, as used in FreeBSD 5.4, NetBSD possibly 2.0, and OpenBSD possibly 3.6, does not properly implement the session timer, which allows remote attackers to cause a denial of service (resource consumption) via crafted packets. | ||||
| CVE-2014-9424 | 1 Openbsd | 1 Libressl | 2025-04-12 | N/A |
| Double free vulnerability in the ssl_parse_clienthello_use_srtp_ext function in d1_srtp.c in LibreSSL before 2.1.2 allows remote attackers to cause a denial of service or possibly have unspecified other impact by triggering a certain length-verification error during processing of a DTLS handshake. | ||||
| CVE-2014-2653 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-12 | N/A |
| The verify_host_key function in sshconnect.c in the client in OpenSSH 6.6 and earlier allows remote servers to trigger the skipping of SSHFP DNS RR checking by presenting an unacceptable HostCertificate. | ||||
| CVE-2015-5600 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-12 | N/A |
| The kbdint_next_device function in auth2-chall.c in sshd in OpenSSH through 6.9 does not properly restrict the processing of keyboard-interactive devices within a single connection, which makes it easier for remote attackers to conduct brute-force attacks or cause a denial of service (CPU consumption) via a long and duplicative list in the ssh -oKbdInteractiveDevices option, as demonstrated by a modified client that provides a different password for each pam element on this list. | ||||
| CVE-2015-6564 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-12 | N/A |
| Use-after-free vulnerability in the mm_answer_pam_free_ctx function in monitor.c in sshd in OpenSSH before 7.0 on non-OpenBSD platforms might allow local users to gain privileges by leveraging control of the sshd uid to send an unexpectedly early MONITOR_REQ_PAM_FREE_CTX request. | ||||
| CVE-2016-10012 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-12 | N/A |
| The shared memory manager (associated with pre-authentication compression) in sshd in OpenSSH before 7.4 does not ensure that a bounds check is enforced by all compilers, which might allows local users to gain privileges by leveraging access to a sandboxed privilege-separation process, related to the m_zback and m_zlib data structures. | ||||
| CVE-2014-9278 | 2 Openbsd, Redhat | 3 Openssh, Enterprise Linux, Fedora | 2025-04-12 | N/A |
| The OpenSSH server, as used in Fedora and Red Hat Enterprise Linux 7 and when running in a Kerberos environment, allows remote authenticated users to log in as another user when they are listed in the .k5users file of that user, which might bypass intended authentication requirements that would force a local login. | ||||
| CVE-2016-10011 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-12 | N/A |
| authfile.c in sshd in OpenSSH before 7.4 does not properly consider the effects of realloc on buffer contents, which might allow local users to obtain sensitive private-key information by leveraging access to a privilege-separated child process. | ||||
| CVE-2015-8325 | 4 Canonical, Debian, Openbsd and 1 more | 6 Ubuntu Core, Ubuntu Linux, Ubuntu Touch and 3 more | 2025-04-12 | N/A |
| The do_setup_env function in session.c in sshd in OpenSSH through 7.2p2, when the UseLogin feature is enabled and PAM is configured to read .pam_environment files in user home directories, allows local users to gain privileges by triggering a crafted environment for the /bin/login program, as demonstrated by an LD_PRELOAD environment variable. | ||||
| CVE-2016-10009 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-12 | N/A |
| Untrusted search path vulnerability in ssh-agent.c in ssh-agent in OpenSSH before 7.4 allows remote attackers to execute arbitrary local PKCS#11 modules by leveraging control over a forwarded agent-socket. | ||||
| CVE-2014-1692 | 1 Openbsd | 1 Openssh | 2025-04-11 | 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-2011-5000 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-11 | N/A |
| The ssh_gssapi_parse_ename function in gss-serv.c in OpenSSH 5.8 and earlier, when gssapi-with-mic authentication is enabled, allows remote authenticated users to cause a denial of service (memory consumption) via a large value in a certain length field. NOTE: there may be limited scenarios in which this issue is relevant. | ||||
| CVE-2011-4327 | 1 Openbsd | 1 Openssh | 2025-04-11 | N/A |
| ssh-keysign.c in ssh-keysign in OpenSSH before 5.8p2 on certain platforms executes ssh-rand-helper with unintended open file descriptors, which allows local users to obtain sensitive key information via the ptrace system call. | ||||
| CVE-2010-4478 | 1 Openbsd | 1 Openssh | 2025-04-11 | N/A |
| OpenSSH 5.6 and earlier, when J-PAKE is enabled, does not properly validate the public parameters in the J-PAKE protocol, which allows remote attackers to bypass the need for knowledge of the shared secret, and successfully authenticate, by sending crafted values in each round of the protocol, a related issue to CVE-2010-4252. | ||||
| CVE-2011-2895 | 6 Freebsd, Freetype, Netbsd and 3 more | 7 Freebsd, Freetype, Netbsd and 4 more | 2025-04-11 | N/A |
| The LZW decompressor in (1) the BufCompressedFill function in fontfile/decompress.c in X.Org libXfont before 1.4.4 and (2) compress/compress.c in 4.3BSD, as used in zopen.c in OpenBSD before 3.8, FreeBSD, NetBSD 4.0.x and 5.0.x before 5.0.3 and 5.1.x before 5.1.1, FreeType 2.1.9, and other products, does not properly handle code words that are absent from the decompression table when encountered, which allows context-dependent attackers to trigger an infinite loop or a heap-based buffer overflow, and possibly execute arbitrary code, via a crafted compressed stream, a related issue to CVE-2006-1168 and CVE-2011-2896. | ||||
| CVE-2011-0539 | 1 Openbsd | 1 Openssh | 2025-04-11 | N/A |
| The key_certify function in usr.bin/ssh/key.c in OpenSSH 5.6 and 5.7, when generating legacy certificates using the -t command-line option in ssh-keygen, does not initialize the nonce field, which might allow remote attackers to obtain sensitive stack memory contents or make it easier to conduct hash collision attacks. | ||||
| CVE-2011-1013 | 3 Linux, Openbsd, Redhat | 4 Linux Kernel, Openbsd, Enterprise Linux and 1 more | 2025-04-11 | 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-2011-2168 | 1 Openbsd | 1 Openbsd | 2025-04-11 | N/A |
| Multiple integer overflows in the glob implementation in libc in OpenBSD before 4.9 might allow context-dependent attackers to have an unspecified impact via a crafted string, related to the GLOB_APPEND and GLOB_DOOFFS flags, a different issue than CVE-2011-0418. | ||||
| CVE-2010-4755 | 3 Freebsd, Netbsd, Openbsd | 4 Freebsd, Netbsd, Openbsd and 1 more | 2025-04-11 | N/A |
| The (1) remote_glob function in sftp-glob.c and the (2) process_put function in sftp.c in OpenSSH 5.8 and earlier, as used in FreeBSD 7.3 and 8.1, NetBSD 5.0.2, OpenBSD 4.7, and other products, allow remote authenticated users to cause a denial of service (CPU and memory consumption) via crafted glob expressions that do not match any pathnames, as demonstrated by glob expressions in SSH_FXP_STAT requests to an sftp daemon, a different vulnerability than CVE-2010-2632. | ||||
| CVE-2012-0814 | 1 Openbsd | 1 Openssh | 2025-04-11 | 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. | ||||
