1 CVE-2017-15906 269 2017-10-25 2019-10-02
5.0
None Remote Low Not required None Partial None
The process_open function in sftp-server.c in OpenSSH before 7.6 does not properly prevent write operations in readonly mode, which allows attackers to create zero-length files.
2 CVE-2016-10708 476 DoS 2018-01-21 2019-06-26
5.0
None Remote Low Not required None None Partial
sshd in OpenSSH before 7.4 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an out-of-sequence NEWKEYS message, as demonstrated by Honggfuzz, related to kex.c and packet.c.
3 CVE-2014-1692 119 DoS Overflow Mem. Corr. 2014-01-29 2017-08-28
7.5
None Remote Low Not required Partial Partial Partial
The hash_buffer function in schnorr.c in OpenSSH through 6.4, when Makefile.inc is modified to enable the J-PAKE protocol, does not initialize certain data structures, which might allow remote attackers to cause a denial of service (memory corruption) or have unspecified other impact via vectors that trigger an error condition.
4 CVE-2012-0814 255 +Info 2012-01-27 2017-08-28
3.5
None Remote Medium Single system Partial None None
The auth_parse_options function in auth-options.c in sshd in OpenSSH before 5.7 provides debug messages containing authorized_keys command options, which allows remote authenticated users to obtain potentially sensitive information by reading these messages, as demonstrated by the shared user account required by Gitolite. NOTE: this can cross privilege boundaries because a user account may intentionally have no shell or filesystem access, and therefore may have no supported way to read an authorized_keys file in its own home directory.
5 CVE-2011-5000 189 DoS 2012-04-05 2012-07-21
3.5
None Remote Medium Single system None None Partial
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.
6 CVE-2011-4327 200 +Info 2014-02-02 2014-02-21
2.1
None Local Low Not required Partial None None
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.
7 CVE-2010-5107 DoS 2013-03-07 2017-09-18
5.0
None Remote Low Not required None None Partial
The default configuration of OpenSSH through 6.1 enforces a fixed time limit between establishing a TCP connection and completing a login, which makes it easier for remote attackers to cause a denial of service (connection-slot exhaustion) by periodically making many new TCP connections.
8 CVE-2010-4755 399 DoS 2011-03-02 2014-08-08
4.0
None Remote Low Single system None None Partial
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.
9 CVE-2010-4478 287 Bypass 2010-12-06 2017-09-18
7.5
None Remote Low Not required Partial Partial Partial
OpenSSH 5.6 and earlier, when J-PAKE is enabled, does not properly validate the public parameters in the J-PAKE protocol, which allows remote attackers to bypass the need for knowledge of the shared secret, and successfully authenticate, by sending crafted values in each round of the protocol, a related issue to CVE-2010-4252.
10 CVE-2008-4109 264 DoS 2008-09-18 2017-08-07
5.0
None Remote Low Not required None None Partial
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.
11 CVE-2008-3259 200 +Info 2008-07-22 2017-08-07
1.2
None Local High Not required Partial None None
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.
12 CVE-2008-1657 264 Bypass 2008-04-02 2018-10-11
6.5
None Remote Low Single system Partial Partial Partial
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.
13 CVE-2007-4752 20 +Priv 2007-09-11 2018-10-15
7.5
User Remote Low Not required Partial Partial Partial
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.
14 CVE-2007-2243 287 2007-04-25 2017-07-28
5.0
None Remote Low Not required Partial None None
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.
15 CVE-2006-5794 Bypass 2006-11-08 2018-10-17
7.5
User Remote Low Not required Partial Partial Partial
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.
