CVE-2008-1147 | 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 2-bit random hops (aka "Algorithm X2"), as used in OpenBSD 2.6 through 3.4, Mac OS X 10 through 10.5.1, FreeBSD 4.4 through 7.0, and DragonFlyBSD 1.0 through 1.10.1, allows remote attackers to guess sensitive values such as IP fragmentation IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as injection into TCP packets and OS fingerprinting. | ||||
CVE-2008-1215 | 3 Freebsd, Netbsd, Openbsd | 3 Freebsd, Netbsd, Openbsd | 2025-04-09 | 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-2008-3234 | 2 Debian, Openbsd | 2 Debian Linux, Openssh | 2025-04-09 | 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-2008-3259 | 1 Openbsd | 1 Openssh | 2025-04-09 | 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-2008-4109 | 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-2006-6730 | 2 Netbsd, Openbsd | 2 Netbsd, Openbsd | 2025-04-09 | 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-2006-5794 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-09 | 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-2007-0343 | 1 Openbsd | 1 Openbsd | 2025-04-09 | N/A |
OpenBSD before 20070116 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via certain IPv6 ICMP (aka ICMP6) echo request packets. | ||||
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-2006-5229 | 2 Novell, Openbsd | 2 Suse Linux, Openssh | 2025-04-09 | N/A |
OpenSSH portable 4.1 on SUSE Linux, and possibly other platforms and versions, and possibly under limited configurations, allows remote attackers to determine valid usernames via timing discrepancies in which responses take longer for valid usernames than invalid ones, as demonstrated by sshtime. NOTE: as of 20061014, it appears that this issue is dependent on the use of manually-set passwords that causes delays when processing /etc/shadow due to an increased number of rounds. | ||||
CVE-2008-0384 | 1 Openbsd | 1 Openbsd | 2025-04-09 | 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-2006-4925 | 1 Openbsd | 1 Openssh | 2025-04-09 | 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-2006-4924 | 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-2006-5051 | 4 Apple, Debian, Openbsd and 1 more | 5 Mac Os X, Mac Os X Server, Debian Linux and 2 more | 2025-04-09 | 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-2007-5365 | 5 Debian, Openbsd, Redhat and 2 more | 7 Debian Linux, Openbsd, Enterprise Linux and 4 more | 2025-04-09 | 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-2007-4752 | 2 Openbsd, Redhat | 3 Openssh, Enterprise Linux, Rhel Eus | 2025-04-09 | N/A |
ssh in OpenSSH before 4.7 does not properly handle when an untrusted cookie cannot be created and uses a trusted X11 cookie instead, which allows attackers to violate intended policy and gain privileges by causing an X client to be treated as trusted. | ||||
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-2006-5052 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-09 | 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-2007-2768 | 2 Netapp, Openbsd | 5 Hci Management Node, Hci Storage Node, Solidfire and 2 more | 2025-04-09 | N/A |
OpenSSH, when using OPIE (One-Time Passwords in Everything) for PAM, allows remote attackers to determine the existence of certain user accounts, which displays a different response if the user account exists and is configured to use one-time passwords (OTP), a similar issue to CVE-2007-2243. | ||||
CVE-2007-2243 | 1 Openbsd | 1 Openssh | 2025-04-09 | 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. |
