CVE-2016-6244 1 Openbsd 1 Openbsd 2017-03-08 7.8 HIGH 7.5 HIGH
The sys_thrsigdivert function in kern/kern_sig.c in the OpenBSD kernel 5.9 allows remote attackers to cause a denial of service (panic) via a negative "ts.tv_sec" value.
CVE-2014-2653 1 Openbsd 1 Openssh 2017-01-07 5.8 MEDIUM N/A
The verify_host_key function in sshconnect.c in the client in OpenSSH 6.6 and earlier allows remote servers to trigger the skipping of SSHFP DNS RR checking by presenting an unacceptable HostCertificate.
CVE-2005-2797 1 Openbsd 1 Openssh 2016-12-08 5.0 MEDIUM N/A
OpenSSH 4.0, and other versions before 4.2, does not properly handle dynamic port forwarding ("-D" option) when a listen address is not provided, which may cause OpenSSH to enable the GatewayPorts functionality.
CVE-2007-1365 1 Openbsd 1 Openbsd 2016-10-18 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-2004-1799 1 Openbsd 1 Openbsd 2016-10-18 7.5 HIGH N/A
PF in certain OpenBSD versions, when stateful filtering is enabled, does not limit packets for a session to the original interface, which allows remote attackers to bypass intended packet filters via spoofed packets to other interfaces.
CVE-2003-0955 1 Openbsd 1 Openbsd 2016-10-18 4.6 MEDIUM N/A
OpenBSD kernel 3.3 and 3.4 allows local users to cause a denial of service (kernel panic) and possibly execute arbitrary code in 3.4 via a program with an invalid header that is not properly handled by (1) ibcs2_exec.c in the iBCS2 emulation (compat_ibcs2) or (2) exec_elf.c, which leads to a stack-based buffer overflow.
CVE-2002-1420 1 Openbsd 1 Openbsd 2016-10-18 7.2 HIGH N/A
Integer signedness error in select() on OpenBSD 3.1 and earlier allows local users to overwrite arbitrary kernel memory via a negative value for the size parameter, which satisfies the boundary check as a signed integer, but is later used as an unsigned integer during a data copying operation.
CVE-2002-0701 2 Freebsd, Openbsd 2 Freebsd, Openbsd 2016-10-18 2.1 LOW N/A
ktrace in BSD-based operating systems allows the owner of a process with special privileges to trace the process after its privileges have been lowered, which may allow the owner to obtain sensitive information that the process obtained while it was running with the extra privileges.
CVE-2002-0575 1 Openbsd 1 Openssh 2016-10-18 7.5 HIGH N/A
Buffer overflow in OpenSSH before 2.9.9, and 3.x before 3.2.1, with Kerberos/AFS support and KerberosTgtPassing or AFSTokenPassing enabled, allows remote and local authenticated users to gain privileges.
CVE-2002-0542 1 Openbsd 1 Openbsd 2016-10-18 7.2 HIGH N/A
mail in OpenBSD 2.9 and 3.0 processes a tilde (~) escape character in a message even when it is not in interactive mode, which could allow local users to gain root privileges via calls to mail in cron.
CVE-2000-1208 4 Immunix, Netbsd, Openbsd and 1 more 4 Immunix, Netbsd, Openbsd and 1 more 2016-10-18 7.2 HIGH N/A
Format string vulnerability in startprinting() function of printjob.c in BSD-based lpr lpd package may allow local users to gain privileges via an improper syslog call that uses format strings from the checkremote() call.
CVE-1999-1010 1 Openbsd 1 Openssh 2016-10-18 2.1 LOW N/A
An SSH 1.2.27 server allows a client to use the "none" cipher, even if it is not allowed by the server policy.
CVE-1999-0798 5 Bsdi, Freebsd, Openbsd and 2 more 7 Bsd Os, Freebsd, Openbsd and 4 more 2016-10-18 10.0 HIGH N/A
Buffer overflow in bootpd on OpenBSD, FreeBSD, and Linux systems via a malformed header type.
CVE-2014-9424 1 Openbsd 1 Libressl 2014-12-30 7.5 HIGH N/A
Double free vulnerability in the ssl_parse_clienthello_use_srtp_ext function in d1_srtp.c in LibreSSL before 2.1.2 allows remote attackers to cause a denial of service or possibly have unspecified other impact by triggering a certain length-verification error during processing of a DTLS handshake.
CVE-2014-7250 4 Bsd, Freebsd, Netbsd and 1 more 4 Bsd, Freebsd, Netbsd and 1 more 2014-12-12 5.0 MEDIUM N/A
The TCP stack in 4.3BSD Net/2, as used in FreeBSD 5.4, NetBSD possibly 2.0, and OpenBSD possibly 3.6, does not properly implement the session timer, which allows remote attackers to cause a denial of service (resource consumption) via crafted packets.
CVE-2010-4755 3 Freebsd, Netbsd, Openbsd 4 Freebsd, Netbsd, Openbsd and 1 more 2014-08-08 4.0 MEDIUM N/A
The (1) remote_glob function in sftp-glob.c and the (2) process_put function in sftp.c in OpenSSH 5.8 and earlier, as used in FreeBSD 7.3 and 8.1, NetBSD 5.0.2, OpenBSD 4.7, and other products, allow remote authenticated users to cause a denial of service (CPU and memory consumption) via crafted glob expressions that do not match any pathnames, as demonstrated by glob expressions in SSH_FXP_STAT requests to an sftp daemon, a different vulnerability than CVE-2010-2632.
CVE-2011-4327 1 Openbsd 1 Openssh 2014-02-21 2.1 LOW N/A
ssh-keysign.c in ssh-keysign in OpenSSH before 5.8p2 on certain platforms executes ssh-rand-helper with unintended open file descriptors, which allows local users to obtain sensitive key information via the ptrace system call.
CVE-2008-4247 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2012-10-23 7.5 HIGH 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-2011-5000 1 Openbsd 1 Openssh 2012-07-22 3.5 LOW N/A
The ssh_gssapi_parse_ename function in gss-serv.c in OpenSSH 5.8 and earlier, when gssapi-with-mic authentication is enabled, allows remote authenticated users to cause a denial of service (memory consumption) via a large value in a certain length field. NOTE: there may be limited scenarios in which this issue is relevant.
CVE-2010-4754 4 Apple, Freebsd, Netbsd and 1 more 4 Mac Os X, Freebsd, Netbsd and 1 more 2011-09-21 4.0 MEDIUM N/A
The glob implementation in libc in FreeBSD 7.3 and 8.1, NetBSD 5.0.2, and OpenBSD 4.7, and Libsystem in Apple Mac OS X before 10.6.8, allows remote authenticated users to cause a denial of service (CPU and memory consumption) via crafted glob expressions that do not match any pathnames, as demonstrated by glob expressions in STAT commands to an FTP daemon, a different vulnerability than CVE-2010-2632.
