CVE-2006-6164 1 Openbsd 1 Openbsd 2025-04-09 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-2008-3844 2 Openbsd, Redhat 4 Openssh, Enterprise Linux, Enterprise Linux Desktop and 1 more 2025-04-09 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-2007-1352 8 Mandrakesoft, Openbsd, Redhat and 5 more 14 Mandrake Linux, Mandrake Linux Corporate Server, Mandrake Multi Network Firewall and 11 more 2025-04-09 N/A
Integer overflow in the FontFileInitTable function in X.Org libXfont before 20070403 allows remote authenticated users to execute arbitrary code via a long first line in the fonts.dir file, which results in a heap overflow.
CVE-2009-0687 4 Midnightbsd, Mirbsd, Netbsd and 1 more 4 Midnightbsd, Miros, Netbsd and 1 more 2025-04-09 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-2006-6397 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2025-04-09 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-2008-4109 2 Debian, Openbsd 2 Linux, Openssh 2025-04-09 N/A
A certain Debian patch for OpenSSH before 4.3p2-9etch3 on etch; before 4.6p1-1 on sid and lenny; and on other distributions such as SUSE uses functions that are not async-signal-safe in the signal handler for login timeouts, which allows remote attackers to cause a denial of service (connection slot exhaustion) via multiple login attempts. NOTE: this issue exists because of an incorrect fix for CVE-2006-5051.
CVE-2009-0780 1 Openbsd 1 Openbsd 2025-04-09 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-2006-4924 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2025-04-09 N/A
sshd in OpenSSH before 4.4, when using the version 1 SSH protocol, allows remote attackers to cause a denial of service (CPU consumption) via an SSH packet that contains duplicate blocks, which is not properly handled by the CRC compensation attack detector.
CVE-2009-3572 1 Openbsd 1 Openbsd 2025-04-09 N/A
OpenBSD 4.4, 4.5, and 4.6, when running on an i386 kernel, does not properly handle XMM exceptions, which allows local users to cause a denial of service (kernel panic) via unspecified vectors.
CVE-2009-0537 2 Microsoft, Openbsd 2 Interix, Openbsd 2025-04-09 N/A
Integer overflow in the fts_build function in fts.c in libc in (1) OpenBSD 4.4 and earlier and (2) Microsoft Interix 6.0 build 10.0.6030.0 allows context-dependent attackers to cause a denial of service (application crash) via a deep directory tree, related to the fts_level structure member, as demonstrated by (a) du, (b) rm, (c) chmod, and (d) chgrp on OpenBSD; and (e) SearchIndexer.exe on Vista Enterprise.
CVE-2008-4609 12 Bsd, Bsdi, Cisco and 9 more 22 Bsd, Bsd Os, Catalyst Blade Switch 3020 and 19 more 2025-04-09 N/A
The TCP implementation in (1) Linux, (2) platforms based on BSD Unix, (3) Microsoft Windows, (4) Cisco products, and probably other operating systems allows remote attackers to cause a denial of service (connection queue exhaustion) via multiple vectors that manipulate information in the TCP state table, as demonstrated by sockstress.
CVE-2006-5550 2 Freebsd, Openbsd 2 Freebsd, Openbsd 2025-04-09 N/A
The kernel in FreeBSD 6.1 and OpenBSD 4.0 allows local users to cause a denial of service via unspecified vectors involving certain ioctl requests to /dev/crypto.
CVE-2007-2242 5 Freebsd, Ietf, Netbsd and 2 more 5 Freebsd, Ipv6, Netbsd and 2 more 2025-04-09 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.
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 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-2008-3831 4 Debian, Linux, Openbsd and 1 more 5 Linux, Linux Kernel, Linux and 2 more 2025-04-09 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-2008-4247 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2025-04-09 N/A
ftpd in OpenBSD 4.3, FreeBSD 7.0, NetBSD 4.0, Solaris, and possibly other operating systems interprets long commands from an FTP client as multiple commands, which allows remote attackers to conduct cross-site request forgery (CSRF) attacks and execute arbitrary FTP commands via a long ftp:// URI that leverages an existing session from the FTP client implementation in a web browser.
CVE-1999-0061 4 Bsdi, Freebsd, Linux and 1 more 4 Bsd Os, Freebsd, Linux Kernel and 1 more 2025-04-03 N/A
File creation and deletion, and remote execution, in the BSD line printer daemon (lpd).
CVE-2000-1010 2 Openbsd, Redhat 2 Openbsd, Linux 2025-04-03 N/A
Format string vulnerability in talkd in OpenBSD and possibly other BSD-based OSes allows remote attackers to execute arbitrary commands via a user name that contains format characters.
CVE-2002-2188 1 Openbsd 1 Openbsd 2025-04-03 N/A
OpenBSD before 3.2 allows local users to cause a denial of service (kernel crash) via a call to getrlimit(2) with invalid arguments, possibly due to an integer signedness error.
CVE-2004-0171 2 Freebsd, Openbsd 2 Freebsd, Openbsd 2025-04-03 N/A
FreeBSD 5.1 and earlier, and Mac OS X before 10.3.4, allows remote attackers to cause a denial of service (resource exhaustion of memory buffers and system crash) via a large number of out-of-sequence TCP packets, which prevents the operating system from creating new connections.
