CVE-2006-6397 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2018-10-17 4.4 MEDIUM N/A
** DISPUTED ** 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-2006-6164 1 Openbsd 1 Openbsd 2018-10-17 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-2006-5794 1 Openbsd 1 Openssh 2018-10-17 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-2006-5229 2 Novell, Openbsd 2 Suse Linux, Openssh 2018-10-17 2.6 LOW 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-2006-4924 1 Openbsd 1 Openssh 2018-10-17 7.8 HIGH 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-2006-5052 1 Openbsd 1 Openssh 2018-10-17 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-2006-4925 1 Openbsd 1 Openssh 2018-10-17 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-2007-2242 4 Freebsd, Ietf, Netbsd and 1 more 4 Freebsd, Ipv6, Netbsd and 1 more 2018-10-16 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.
CVE-2007-1352 8 Mandrakesoft, Openbsd, Redhat and 5 more 14 Mandrake Linux, Mandrake Linux Corporate Server, Mandrake Multi Network Firewall and 11 more 2018-10-16 3.8 LOW 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-2007-1351 7 Mandrakesoft, Openbsd, Redhat and 4 more 11 Mandrake Linux, Mandrake Linux Corporate Server, Mandrake Multi Network Firewall and 8 more 2018-10-16 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 2018-10-15 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-2007-4752 1 Openbsd 1 Openssh 2018-10-15 7.5 HIGH 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-2007-4654 3 Cisco, Openbsd, Teamf1 4 Content Services Switch 11000, Webns, Openssh and 1 more 2018-10-15 5.0 MEDIUM N/A
Unspecified vulnerability in SSHield 1.6.1 with OpenSSH 3.0.2p1 on Cisco WebNS 8.20.0.1 on Cisco Content Services Switch (CSS) series 11000 devices allows remote attackers to cause a denial of service (connection slot exhaustion and device crash) via a series of large packets designed to exploit the SSH CRC32 attack detection overflow (CVE-2001-0144), possibly a related issue to CVE-2002-1024.
CVE-2009-0537 2 Microsoft, Openbsd 2 Interix, Openbsd 2018-10-11 4.9 MEDIUM 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-2008-5161 2 Openbsd, Ssh 5 Openssh, Tectia Client, Tectia Connector and 2 more 2018-10-11 2.6 LOW N/A
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-2008-1483 1 Openbsd 1 Openssh 2018-10-11 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-2008-1657 1 Openbsd 1 Openssh 2018-10-11 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-2018-14775 1 Openbsd 1 Openbsd 2018-10-03 4.9 MEDIUM 5.5 MEDIUM
tss_alloc in sys/arch/i386/i386/gdt.c in OpenBSD 6.2 and 6.3 has a Local Denial of Service (system crash) due to incorrect I/O port access control on the i386 architecture.
CVE-2016-3115 2 Openbsd, Oracle 2 Openssh, Vm Server 2018-09-11 5.5 MEDIUM 6.4 MEDIUM
Multiple CRLF injection vulnerabilities in session.c in sshd in OpenSSH before 7.2p2 allow remote authenticated users to bypass intended shell-command restrictions via crafted X11 forwarding data, related to the (1) do_authenticated1 and (2) session_x11_req functions.
CVE-2018-12434 1 Openbsd 1 Libressl 2018-08-06 1.9 LOW 4.7 MEDIUM
LibreSSL before 2.6.5 and 2.7.x before 2.7.4 allows a memory-cache side-channel attack on DSA and ECDSA signatures, aka the Return Of the Hidden Number Problem or ROHNP. To discover a key, the attacker needs access to either the local machine or a different virtual machine on the same physical host.
