CVE-2017-1000372 1 Openbsd 1 Openbsd 2025-04-20 N/A
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-2016-6241 1 Openbsd 1 Openbsd 2025-04-20 N/A
Integer overflow in the amap_alloc1 function in OpenBSD 5.8 and 5.9 allows local users to execute arbitrary code with kernel privileges via a large size value.
CVE-2016-6244 1 Openbsd 1 Openbsd 2025-04-20 N/A
The sys_thrsigdivert function in kern/kern_sig.c in the OpenBSD kernel 5.9 allows remote attackers to cause a denial of service (panic) via a negative "ts.tv_sec" value.
CVE-2016-6522 1 Openbsd 1 Openbsd 2025-04-20 N/A
Integer overflow in the uvm_map_isavail function in uvm/uvm_map.c in OpenBSD 5.9 allows local users to cause a denial of service (kernel panic) via a crafted mmap call, which triggers the new mapping to overlap with an existing mapping.
CVE-2016-6239 1 Openbsd 1 Openbsd 2025-04-20 N/A
The mmap extension __MAP_NOFAULT in OpenBSD 5.8 and 5.9 allows attackers to cause a denial of service (kernel panic and crash) via a large size value.
CVE-2016-6240 1 Openbsd 1 Openbsd 2025-04-20 N/A
Integer truncation error in the amap_alloc function in OpenBSD 5.8 and 5.9 allows local users to execute arbitrary code with kernel privileges via a large size value.
CVE-2016-6242 1 Openbsd 1 Openbsd 2025-04-20 N/A
OpenBSD 5.8 and 5.9 allows local users to cause a denial of service (assertion failure and kernel panic) via a large ident value in a kevent system call.
CVE-2016-6245 1 Openbsd 1 Openbsd 2025-04-20 N/A
OpenBSD 5.8 and 5.9 allows local users to cause a denial of service (kernel panic) via a large size in a getdents system call.
CVE-2016-6246 1 Openbsd 1 Openbsd 2025-04-20 N/A
OpenBSD 5.8 and 5.9 allows certain local users with kern.usermount privileges to cause a denial of service (kernel panic) by mounting a tmpfs with a VNOVAL in the (1) username, (2) groupname, or (3) device name of the root node.
CVE-2016-6247 1 Openbsd 1 Openbsd 2025-04-20 N/A
OpenBSD 5.8 and 5.9 allows certain local users to cause a denial of service (kernel panic) by unmounting a filesystem with an open vnode on the mnt_vnodelist.
CVE-2016-6350 1 Openbsd 1 Openbsd 2025-04-20 N/A
OpenBSD 5.8 and 5.9 allows local users to cause a denial of service (NULL pointer dereference and panic) via a sysctl call with a path starting with 10,9.
CVE-2017-8301 1 Openbsd 1 Libressl 2025-04-20 N/A
LibreSSL 2.5.1 to 2.5.3 lacks TLS certificate verification if SSL_get_verify_result is relied upon for a later check of a verification result, in a use case where a user-provided verification callback returns 1, as demonstrated by acceptance of invalid certificates by nginx.
CVE-2016-6515 3 Fedoraproject, Openbsd, Redhat 3 Fedora, Openssh, Enterprise Linux 2025-04-12 N/A
The auth_password function in auth-passwd.c in sshd in OpenSSH before 7.3 does not limit password lengths for password authentication, which allows remote attackers to cause a denial of service (crypt CPU consumption) via a long string.
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-2016-0778 6 Apple, Hp, Openbsd and 3 more 7 Mac Os X, Virtual Customer Access System, Openssh and 4 more 2025-04-12 N/A
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-2016-10010 1 Openbsd 1 Openssh 2025-04-12 N/A
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-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-2016-3115 3 Openbsd, Oracle, Redhat 3 Openssh, Vm Server, Enterprise Linux 2025-04-12 N/A
Multiple CRLF injection vulnerabilities in session.c in sshd in OpenSSH before 7.2p2 allow remote authenticated users to bypass intended shell-command restrictions via crafted X11 forwarding data, related to the (1) do_authenticated1 and (2) session_x11_req functions.
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-2014-9278 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.
