IPFilter 3.4.16 and earlier does not include sufficient session information in its cache, which allows remote attackers to bypass access restrictions by sending fragmented packets to a restricted port after sending unfragmented packets to an unrestricted port.
CVE-2001-0378 1 Openbsd 1 Openbsd 2017-10-10 2.1 LOW N/A
readline prior to 4.1, in OpenBSD 2.8 and earlier, creates history files with insecure permissions, which allows a local attacker to recover potentially sensitive information via readline history files.

The i386_set_ldt system call in NetBSD 1.5 and earlier, and OpenBSD 2.8 and earlier, when the USER_LDT kernel option is enabled, does not validate a call gate target, which allows local users to gain root privileges by creating a segment call gate in the Local Descriptor Table (LDT) with a target that specifies an arbitrary kernel address.
CVE-2001-0053 3 David Madore, Netbsd, Openbsd 3 Ftpd-bsd, Netbsd, Openbsd 2017-10-10 10.0 HIGH N/A

Format string vulnerability in OpenBSD photurisd allows local users to execute arbitrary commands via a configuration file directory name that contains formatting characters.
CVE-2000-0993 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2017-10-10 7.2 HIGH N/A
Format string vulnerability in pw_error function in BSD libutil library allows local users to gain root privileges via a malformed password in commands such as chpass or passwd.
CVE-2000-0914 1 Openbsd 1 Openbsd 2017-10-10 5.0 MEDIUM N/A
OpenBSD 2.6 and earlier allows remote attackers to cause a denial of service by flooding the server with ARP requests.
CVE-1999-1214 5 Bsd, Freebsd, Netbsd and 2 more 5 Bsd, Freebsd, Netbsd and 2 more 2017-10-10 2.1 LOW N/A
The asynchronous I/O facility in 4.4 BSD kernel does not check user credentials when setting the recipient of I/O notification, which allows local users to cause a denial of service by using certain ioctl and fcntl calls to cause the signal to be sent to an arbitrary process ID.
CVE-2009-0687 4 Midnightbsd, Mirbsd, Netbsd and 1 more 4 Midnightbsd, Miros, Netbsd and 1 more 2017-09-29 7.8 HIGH N/A
The pf_test_rule function in OpenBSD Packet Filter (PF), as used in OpenBSD 4.2 through 4.5, NetBSD 5.0 before RC3, MirOS 10 and earlier, and MidnightBSD 0.3-current allows remote attackers to cause a denial of service (panic) via crafted IP packets that trigger a NULL pointer dereference during translation, related to an IPv4 packet with an ICMPv6 payload.
CVE-2008-2476 6 Force10, Freebsd, Juniper and 3 more 6 Ftos, Freebsd, Jnos and 3 more 2017-09-29 9.3 HIGH N/A
The IPv6 Neighbor Discovery Protocol (NDP) implementation in (1) FreeBSD 6.3 through 7.1, (2) OpenBSD 4.2 and 4.3, (3) NetBSD, (4) Force10 FTOS before E7.7.1.1, (5) Juniper JUNOS, and (6) Wind River VxWorks 5.x through 6.4 does not validate the origin of Neighbor Discovery messages, which allows remote attackers to cause a denial of service (loss of connectivity) or read private network traffic via a spoofed message that modifies the Forward Information Base (FIB).
CVE-2016-6241 1 Openbsd 1 Openbsd 2017-09-01 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-2016-6240 1 Openbsd 1 Openbsd 2017-09-01 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-2016-6239 1 Openbsd 1 Openbsd 2017-09-01 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-2011-2895 5 Freebsd, Freetype, Netbsd and 2 more 5 Freebsd, Freetype, Netbsd and 2 more 2017-08-29 9.3 HIGH 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-2009-0780 1 Openbsd 1 Openbsd 2017-08-17 5.0 MEDIUM N/A
The aspath_prepend function in rde_attr.c in bgpd in OpenBSD 4.3 and 4.4 allows remote attackers to cause a denial of service (application crash) via an Autonomous System (AS) advertisement containing a long AS path.
CVE-2008-1215 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2017-08-08 4.6 MEDIUM N/A
Stack-based buffer overflow in the command_Expand_Interpret function in command.c in ppp (aka user-ppp), as distributed in FreeBSD 6.3 and 7.0, OpenBSD 4.1 and 4.2, and the net/userppp package for NetBSD, allows local users to gain privileges via long commands containing "~" characters.
CVE-2008-1148 8 Apple, Cosmicperl, Darwin and 5 more 9 Mac Os X, Mac Os X Server, Directory Pro and 6 more 2017-08-08 6.8 MEDIUM N/A
A certain pseudo-random number generator (PRNG) algorithm that uses ADD with 0 random hops (aka "Algorithm A0"), as used in OpenBSD 3.5 through 4.2 and NetBSD 1.6.2 through 4.0, allows remote attackers to guess sensitive values such as (1) DNS transaction IDs or (2) IP fragmentation IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as DNS cache poisoning, injection into TCP packets, and OS fingerprinting.
CVE-2008-1146 8 Apple, Cosmicperl, Darwin and 5 more 9 Mac Os X, Mac Os X Server, Directory Pro and 6 more 2017-08-08 6.8 MEDIUM N/A
A certain pseudo-random number generator (PRNG) algorithm that uses XOR and 3-bit random hops (aka "Algorithm X3"), as used in OpenBSD 2.8 through 4.2, allows remote attackers to guess sensitive values such as DNS transaction IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as DNS cache poisoning against OpenBSD's modification of BIND.
CVE-2007-0085 1 Openbsd 1 Openbsd 2017-07-29 6.0 MEDIUM N/A
Unspecified vulnerability in sys/dev/pci/vga_pci.c in the VGA graphics driver for wscons in OpenBSD 3.9 and 4.0, when the kernel is compiled with the PCIAGP option and a non-AGP device is being used, allows local users to gain privileges via unspecified vectors, possibly related to agp_ioctl NULL pointer reference.
