CVE-2017-5850 1 Openbsd 1 Openbsd 2025-04-20 N/A
httpd in OpenBSD allows remote attackers to cause a denial of service (memory consumption) via a series of requests for a large file using an HTTP Range header.
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-2015-7687 2 Fedoraproject, Openbsd 2 Fedora, Opensmtpd 2025-04-20 N/A
Use-after-free vulnerability in OpenSMTPD before 5.7.2 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via vectors involving req_ca_vrfy_smtp and req_ca_vrfy_mta.
CVE-2017-1000373 1 Openbsd 1 Openbsd 2025-04-20 N/A
The OpenBSD qsort() function is recursive, and not randomized, an attacker can construct a pathological input array of N elements that causes qsort() to deterministically recurse N/4 times. This allows attackers to consume arbitrary amounts of stack memory and manipulate stack memory to assist in arbitrary code execution attacks. This affects OpenBSD 6.1 and possibly earlier versions.
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-2016-6243 1 Openbsd 1 Openbsd 2025-04-20 N/A
thrsleep in kern/kern_synch.c in OpenBSD 5.8 and 5.9 allows local users to cause a denial of service (kernel panic) via a crafted value in the tsp parameter of the __thrsleep 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-2016-6350 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-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-2016-6241 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-2016-10011 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-2016-0777 6 Apple, Hp, Openbsd and 3 more 8 Mac Os X, Remote Device Access Virtual Customer Access System, Openssh and 5 more 2025-04-12 N/A
The resend_bytes function in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2 allows remote servers to obtain sensitive information from process memory by requesting transmission of an entire buffer, as demonstrated by reading a private key.
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-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-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-2016-8858 1 Openbsd 1 Openssh 2025-04-12 N/A
The kex_input_kexinit function in kex.c in OpenSSH 6.x and 7.x through 7.3 allows remote attackers to cause a denial of service (memory consumption) by sending many duplicate KEXINIT requests. NOTE: a third party reports that "OpenSSH upstream does not consider this as a security issue."
CVE-2014-2532 3 Openbsd, Oracle, Redhat 3 Openssh, Communications User Data Repository, Enterprise Linux 2025-04-12 N/A
sshd in OpenSSH before 6.6 does not properly support wildcards on AcceptEnv lines in sshd_config, which allows remote attackers to bypass intended environment restrictions by using a substring located before a wildcard character.
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-2016-1907 1 Openbsd 1 Openssh 2025-04-12 N/A
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-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.
