1 CVE-2017-15906 269 2017-10-25 2019-10-02
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
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
None Remote Low Not required Partial Partial Partial
The hash_buffer function in schnorr.c in OpenSSH through 6.4, when 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
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-2011-4327 200 +Info 2014-02-02 2014-02-21
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.
6 CVE-2008-4109 264 DoS 2008-09-18 2017-08-07
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.
7 CVE-2003-1562 362 2003-12-31 2008-09-05
Admin Remote High Not required Complete Complete Complete
sshd in OpenSSH 3.6.1p2 and earlier, when PermitRootLogin is disabled and using PAM keyboard-interactive authentication, does not insert a delay after a root login attempt with the correct password, which makes it easier for remote attackers to use timing differences to determine if the password step of a multi-step authentication is successful, a different vulnerability than CVE-2003-0190.
