CVE-2016-6522 | 1 Openbsd | 1 Openbsd | 2025-04-20 | 4.9 MEDIUM | 5.5 MEDIUM |
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. | |||||

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-2017-15906 | 5 Debian, Netapp, Openbsd and 2 more | 22 Debian Linux, Active Iq Unified Manager, Cloud Backup and 19 more | 2025-04-20 | 5.0 MEDIUM | 5.3 MEDIUM |

CVE-2016-6210 | 1 Openbsd | 1 Openssh | 2025-04-20 | 4.3 MEDIUM | 5.9 MEDIUM |
sshd in OpenSSH before 7.3, when SHA256 or SHA512 are used for user password hashing, uses BLOWFISH hashing on a static password when the username does not exist, which allows remote attackers to enumerate users by leveraging the timing difference between responses when a large password is provided. | |||||
CVE-2016-6244 | 1 Openbsd | 1 Openbsd | 2025-04-20 | 7.8 HIGH | 7.5 HIGH |
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-2017-8301 | 1 Openbsd | 1 Libressl | 2025-04-20 | 2.6 LOW | 5.3 MEDIUM |
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-2016-6245 | 1 Openbsd | 1 Openbsd | 2025-04-20 | 4.9 MEDIUM | 5.5 MEDIUM |
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-2017-5850 | 1 Openbsd | 1 Openbsd | 2025-04-20 | 7.8 HIGH | 7.5 HIGH |
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-2016-1908 | 4 Debian, Openbsd, Oracle and 1 more | 9 Debian Linux, Openssh, Linux and 6 more | 2025-04-20 | 7.5 HIGH | 9.8 CRITICAL |
The client in OpenSSH before 7.2 mishandles failed cookie generation for untrusted X11 forwarding and relies on the local X11 server for access-control decisions, which allows remote X11 clients to trigger a fallback and obtain trusted X11 forwarding privileges by leveraging configuration issues on this X11 server, as demonstrated by lack of the SECURITY extension on this X11 server. | |||||
CVE-2016-6240 | 1 Openbsd | 1 Openbsd | 2025-04-20 | 7.2 HIGH | 7.8 HIGH |
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-2016-6241 | 1 Openbsd | 1 Openbsd | 2025-04-20 | 7.2 HIGH | 7.8 HIGH |
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-2016-6239 | 1 Openbsd | 1 Openbsd | 2025-04-20 | 4.9 MEDIUM | 5.5 MEDIUM |
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-2016-6247 | 1 Openbsd | 1 Openbsd | 2025-04-20 | 4.9 MEDIUM | 5.5 MEDIUM |
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-2015-7687 | 2 Fedoraproject, Openbsd | 2 Fedora, Opensmtpd | 2025-04-20 | 7.5 HIGH | 9.8 CRITICAL |
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-2015-8325 | 3 Canonical, Debian, Openbsd | 5 Ubuntu Core, Ubuntu Linux, Ubuntu Touch and 2 more | 2025-04-12 | 7.2 HIGH | 7.8 HIGH |
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. | |||||

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. | |||||
