|---|---|---|---|---|---|
| CVE-2008-1146 | 8 Apple, Cosmicperl, Darwin and 5 more | 9 Mac Os X, Mac Os X Server, Directory Pro and 6 more | 2025-04-09 | 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-2008-1483 | 1 Openbsd | 1 Openssh | 2025-04-09 | 6.9 MEDIUM | N/A |
| OpenSSH 4.3p2, and probably other versions, allows local users to hijack forwarded X connections by causing ssh to set DISPLAY to :10, even when another process is listening on the associated port, as demonstrated by opening TCP port 6010 (IPv4) and sniffing a cookie sent by Emacs. | |||||
| CVE-2009-2904 | 3 Fedoraproject, Openbsd, Redhat | 5 Fedora, Openssh, Enterprise Linux and 2 more | 2025-04-09 | 6.9 MEDIUM | N/A |
| A certain Red Hat modification to the ChrootDirectory feature in OpenSSH 4.8, as used in sshd in OpenSSH 4.3 in Red Hat Enterprise Linux (RHEL) 5.4 and Fedora 11, allows local users to gain privileges via hard links to setuid programs that use configuration files within the chroot directory, related to requirements for directory ownership. | |||||
| CVE-2008-1057 | 1 Openbsd | 1 Openbsd | 2025-04-09 | 7.8 HIGH | N/A |
| The ip6_check_rh0hdr function in netinet6/ip6_input.c in OpenBSD 4.2 allows attackers to cause a denial of service (panic) via malformed IPv6 routing headers. | |||||
| CVE-2006-6730 | 2 Netbsd, Openbsd | 2 Netbsd, Openbsd | 2025-04-09 | 6.6 MEDIUM | N/A |
| OpenBSD and NetBSD permit usermode code to kill the display server and write to the X.Org /dev/xf86 device, which allows local users with root privileges to reduce securelevel by replacing the System Management Mode (SMM) handler via a write to an SMRAM address within /dev/xf86 (aka the video card memory-mapped I/O range), and then launching the new handler via a System Management Interrupt (SMI), as demonstrated by a write to Programmed I/O port 0xB2. | |||||
| CVE-2007-4305 | 5 Netbsd, Openbsd, Sysjail and 2 more | 5 Netbsd, Openbsd, Sysjail and 2 more | 2025-04-09 | 6.2 MEDIUM | N/A |
| Multiple race conditions in the (1) Sudo monitor mode and (2) Sysjail policies in Systrace on NetBSD and OpenBSD allow local users to defeat system call interposition, and consequently bypass access control policy and auditing. | |||||
| CVE-2006-5051 | 3 Apple, Debian, Openbsd | 4 Mac Os X, Mac Os X Server, Debian Linux and 1 more | 2025-04-09 | 9.3 HIGH | 8.1 HIGH |
| Signal handler race condition in OpenSSH before 4.4 allows remote attackers to cause a denial of service (crash), and possibly execute arbitrary code if GSSAPI authentication is enabled, via unspecified vectors that lead to a double-free. | |||||
| CVE-2008-1058 | 1 Openbsd | 1 Openbsd | 2025-04-09 | 7.8 HIGH | N/A |
| The tcp_respond function in netinet/tcp_subr.c in OpenBSD 4.1 and 4.2 allows attackers to cause a denial of service (panic) via crafted TCP packets. NOTE: some of these details are obtained from third party information. | |||||
| CVE-2006-6397 | 3 Freebsd, Netbsd, Openbsd | 3 Freebsd, Netbsd, Openbsd | 2025-04-09 | 4.4 MEDIUM | N/A |
| Integer overflow in banner/banner.c in FreeBSD, NetBSD, and OpenBSD might allow local users to modify memory via a long banner. NOTE: CVE and multiple third parties dispute this issue. Since banner is not setuid, an exploit would not cross privilege boundaries in normal operations. This issue is not a vulnerability | |||||
| CVE-2008-1657 | 1 Openbsd | 1 Openssh | 2025-04-09 | 6.5 MEDIUM | N/A |
| OpenSSH 4.4 up to versions before 4.9 allows remote authenticated users to bypass the sshd_config ForceCommand directive by modifying the .ssh/rc session file. | |||||
| CVE-2006-5218 | 2 Netbsd, Openbsd | 2 Netbsd, Openbsd | 2025-04-09 | 4.6 MEDIUM | N/A |
| Integer overflow in the systrace_preprepl function (STRIOCREPLACE) in systrace in OpenBSD 3.9 and NetBSD 3 allows local users to cause a denial of service (crash), gain privileges, or read arbitrary kernel memory via large numeric arguments to the systrace ioctl. | |||||
| CVE-2006-4925 | 1 Openbsd | 1 Openssh | 2025-04-09 | 5.0 MEDIUM | N/A |
| packet.c in ssh in OpenSSH allows remote attackers to cause a denial of service (crash) by sending an invalid protocol sequence with USERAUTH_SUCCESS before NEWKEYS, which causes newkeys[mode] to be NULL. | |||||
| CVE-2006-6164 | 1 Openbsd | 1 Openbsd | 2025-04-09 | 7.2 HIGH | N/A |
| The _dl_unsetenv function in loader.c in the ELF ld.so in OpenBSD 3.9 and 4.0 does not properly remove duplicate environment variables, which allows local users to pass dangerous variables such as LD_PRELOAD to loading processes, which might be leveraged to gain privileges. | |||||
| CVE-2007-2243 | 1 Openbsd | 1 Openssh | 2025-04-09 | 5.0 MEDIUM | N/A |
| OpenSSH 4.6 and earlier, when ChallengeResponseAuthentication is enabled, allows remote attackers to determine the existence of user accounts by attempting to authenticate via S/KEY, which displays a different response if the user account exists, a similar issue to CVE-2001-1483. | |||||
| CVE-2008-3831 | 3 Debian, Linux, Openbsd | 3 Linux, Linux Kernel, Linux | 2025-04-09 | 4.7 MEDIUM | N/A |
| The i915 driver in (1) drivers/char/drm/i915_dma.c in the Linux kernel 2.6.24 on Debian GNU/Linux and (2) sys/dev/pci/drm/i915_drv.c in OpenBSD does not restrict the DRM_I915_HWS_ADDR ioctl to the Direct Rendering Manager (DRM) master, which allows local users to cause a denial of service (memory corruption) via a crafted ioctl call, related to absence of the DRM_MASTER and DRM_ROOT_ONLY flags in the ioctl's configuration. | |||||
| CVE-2008-3844 | 2 Openbsd, Redhat | 3 Openssh, Enterprise Linux, Enterprise Linux Desktop | 2025-04-09 | 9.3 HIGH | N/A |
| Certain Red Hat Enterprise Linux (RHEL) 4 and 5 packages for OpenSSH, as signed in August 2008 using a legitimate Red Hat GPG key, contain an externally introduced modification (Trojan Horse) that allows the package authors to have an unknown impact. NOTE: since the malicious packages were not distributed from any official Red Hat sources, the scope of this issue is restricted to users who may have obtained these packages through unofficial distribution points. As of 20080827, no unofficial distributions of this software are known. | |||||
| CVE-2007-2242 | 4 Freebsd, Ietf, Netbsd and 1 more | 4 Freebsd, Ipv6, Netbsd and 1 more | 2025-04-09 | 7.8 HIGH | N/A |
| The IPv6 protocol allows remote attackers to cause a denial of service via crafted IPv6 type 0 route headers (IPV6_RTHDR_TYPE_0) that create network amplification between two routers. | |||||

| OpenSSH before 5.1 sets the SO_REUSEADDR socket option when the X11UseLocalhost configuration setting is disabled, which allows local users on some platforms to hijack the X11 forwarding port via a bind to a single IP address, as demonstrated on the HP-UX platform. | |||||
| CVE-2009-0687 | 4 Midnightbsd, Mirbsd, Netbsd and 1 more | 4 Midnightbsd, Miros, Netbsd and 1 more | 2025-04-09 | 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-2009-0780 | 1 Openbsd | 1 Openbsd | 2025-04-09 | 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. | |||||
