1 CVE-2017-1000373 400 Exec Code 2017-06-19 2017-08-11
6.4
None Remote Low Not required None Partial Partial
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.
2 CVE-2017-1000372 284 Exec Code Bypass 2017-06-19 2017-06-29
7.5
None Remote Low Not required Partial Partial Partial
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.
3 CVE-2017-5850 399 DoS 2017-03-27 2017-03-31
7.8
None Remote Low Not required None None Complete
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.
4 CVE-2016-6522 190 DoS Overflow 2017-03-07 2017-03-08
4.9
None Local Low Not required None None Complete
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.
5 CVE-2016-6350 476 DoS 2017-03-07 2017-03-08
4.9
None Local Low Not required None None Complete
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.
6 CVE-2016-6247 20 DoS 2017-03-07 2017-03-08
4.9
None Local Low Not required None None Complete
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.
7 CVE-2016-6246 20 DoS 2017-03-07 2017-03-08
4.9
None Local Low Not required None None Complete
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.
8 CVE-2016-6245 DoS 2017-03-07 2017-03-08
4.9
None Local Low Not required None None Complete
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.
9 CVE-2016-6244 20 DoS 2017-03-07 2017-03-08
7.8
None Remote Low Not required None None Complete
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.
10 CVE-2016-6243 20 DoS 2017-03-07 2017-03-08
4.9
None Local Low Not required None None Complete
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.
11 CVE-2016-6242 189 DoS 2017-03-07 2017-03-08
4.9
None Local Low Not required None None Complete
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.
12 CVE-2016-6241 190 Exec Code Overflow 2017-03-07 2017-08-31
7.2
None Local Low Not required Complete Complete Complete
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.
13 CVE-2016-6240 189 Exec Code 2017-03-07 2017-08-31
7.2
None Local Low Not required Complete Complete Complete
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.
14 CVE-2016-6239 20 DoS 2017-03-07 2017-08-31
4.9
None Local Low Not required None None Complete
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.
