CVE-2006-5052 | 1 Openbsd | 1 Openssh | 2025-04-09 | 5.0 MEDIUM | N/A |
Unspecified vulnerability in portable OpenSSH before 4.4, when running on some platforms, allows remote attackers to determine the validity of usernames via unknown vectors involving a GSSAPI "authentication abort." | |||||
CVE-2007-0085 | 1 Openbsd | 1 Openbsd | 2025-04-09 | 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. | |||||
CVE-2008-0384 | 1 Openbsd | 1 Openbsd | 2025-04-09 | 4.9 MEDIUM | N/A |
OpenBSD 4.2 allows local users to cause a denial of service (kernel panic) by calling the SIOCGIFRTLABEL IOCTL on an interface that does not have a route label, which triggers a NULL pointer dereference when the return value from the rtlabel_id2name function is not checked. | |||||
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-2008-3234 | 2 Debian, Openbsd | 2 Debian Linux, Openssh | 2025-04-09 | 6.5 MEDIUM | N/A |
sshd in OpenSSH 4 on Debian GNU/Linux, and the 20070303 OpenSSH snapshot, allows remote authenticated users to obtain access to arbitrary SELinux roles by appending a :/ (colon slash) sequence, followed by the role name, to the username. | |||||
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-2006-5550 | 2 Freebsd, Openbsd | 2 Freebsd, Openbsd | 2025-04-09 | 4.9 MEDIUM | 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-2008-3259 | 1 Openbsd | 1 Openssh | 2025-04-09 | 1.2 LOW | N/A |
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-2008-1057 | 1 Openbsd | 1 Openbsd | 2025-04-09 | 7.8 HIGH | N/A |

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-2006-5794 | 1 Openbsd | 1 Openssh | 2025-04-09 | 7.5 HIGH | N/A |
Unspecified vulnerability in the sshd Privilege Separation Monitor in OpenSSH before 4.5 causes weaker verification that authentication has been successful, which might allow attackers to bypass authentication. NOTE: as of 20061108, it is believed that this issue is only exploitable by leveraging vulnerabilities in the unprivileged process, which are not known to exist. | |||||
CVE-2007-1365 | 1 Openbsd | 1 Openbsd | 2025-04-09 | 10.0 HIGH | N/A |
Buffer overflow in kern/uipc_mbuf2.c in OpenBSD 3.9 and 4.0 allows remote attackers to execute arbitrary code via fragmented IPv6 packets due to "incorrect mbuf handling for ICMP6 packets." NOTE: this was originally reported as a denial of service. | |||||
CVE-2008-1215 | 3 Freebsd, Netbsd, Openbsd | 3 Freebsd, Netbsd, Openbsd | 2025-04-09 | 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-2009-3572 | 1 Openbsd | 1 Openbsd | 2025-04-09 | 4.9 MEDIUM | 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-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-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. | |||||

Error handling in the SSH protocol in (1) SSH Tectia Client and Server and Connector 4.0 through 4.4.11, 5.0 through 5.2.4, and 5.3 through 5.3.8; Client and Server and ConnectSecure 6.0 through 6.0.4; Server for Linux on IBM System z 6.0.4; Server for IBM z/OS 5.5.1 and earlier, 6.0.0, and 6.0.1; and Client 4.0-J through 4.3.3-J and 4.0-K through 4.3.10-K; and (2) OpenSSH 4.7p1 and possibly other versions, when using a block cipher algorithm in Cipher Block Chaining (CBC) mode, makes it easier for remote attackers to recover certain plaintext data from an arbitrary block of ciphertext in an SSH session via unknown vectors. | |||||
CVE-2007-1351 | 7 Mandrakesoft, Openbsd, Redhat and 4 more | 11 Mandrake Linux, Mandrake Linux Corporate Server, Mandrake Multi Network Firewall and 8 more | 2025-04-09 | 8.5 HIGH | N/A |
Integer overflow in the bdfReadCharacters function in bdfread.c in (1) X.Org libXfont before 20070403 and (2) freetype 2.3.2 and earlier allows remote authenticated users to execute arbitrary code via crafted BDF fonts, which result in a heap overflow. | |||||
CVE-2007-5365 | 5 Debian, Openbsd, Redhat and 2 more | 7 Debian Linux, Openbsd, Enterprise Linux and 4 more | 2025-04-09 | 7.2 HIGH | N/A |
Stack-based buffer overflow in the cons_options function in options.c in dhcpd in OpenBSD 4.0 through 4.2, and some other dhcpd implementations based on ISC dhcp-2, allows remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a DHCP request specifying a maximum message size smaller than the minimum IP MTU. | |||||
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. |
