V2: 6.4 MEDIUM
CVE-2004-0175

Directory traversal vulnerability in scp for OpenSSH before 3.4p1 allows remote malicious servers to overwrite arbitrary files. NOTE: this may be a rediscovery of CVE-2000-0992.

CVE-2003-1562

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.

V2: 7.6 HIGH
CVE-2003-0786

The SSH1 PAM challenge response authentication in OpenSSH 3.7.1 and 3.7.1p1, when Privilege Separation is disabled, does not check the result of the authentication attempt, which can allow remote attackers to gain privileges.

Published: November 17, 2003; 12:00:00 AM -05:00
V2: 10.0 HIGH
CVE-2003-0787

The PAM conversation function in OpenSSH 3.7.1 and 3.7.1p1 interprets an array of structures as an array of pointers, which allows attackers to modify the stack and possibly gain privileges.

Published: November 17, 2003; 12:00:00 AM -05:00
V2: 7.5 HIGH
CVE-2003-0682

"Memory bugs" in OpenSSH 3.7.1 and earlier, with unknown impact, a different set of vulnerabilities than CVE-2003-0693 and CVE-2003-0695.

Published: October 06, 2003; 12:00:00 AM -04:00
V2: 7.5 HIGH
CVE-2003-0695

Multiple "buffer management errors" in OpenSSH before 3.7.1 may allow attackers to cause a denial of service or execute arbitrary code using (1) buffer_init in buffer.c, (2) buffer_free in buffer.c, or (3) a separate function in channels.c, a different vulnerability than CVE-2003-0693.

Published: October 06, 2003; 12:00:00 AM -04:00
V2: 7.5 HIGH
CVE-2003-0693

A "buffer management error" in buffer_append_space of buffer.c for OpenSSH before 3.7 may allow remote attackers to execute arbitrary code by causing an incorrect amount of memory to be freed and corrupting the heap, a different vulnerability than CVE-2003-0695.

Published: September 22, 2003; 12:00:00 AM -04:00
V2: 10.0 HIGH
CVE-2003-0386

OpenSSH 3.6.1 and earlier, when restricting host access by numeric IP addresses and with VerifyReverseMapping disabled, allows remote attackers to bypass "from=" and "user@host" address restrictions by connecting to a host from a system whose reverse DNS hostname contains the numeric IP address.

Published: July 02, 2003; 12:00:00 AM -04:00
V2: 7.5 HIGH
CVE-2003-0190

OpenSSH-portable (OpenSSH) 3.6.1p1 and earlier with PAM support enabled immediately sends an error message when a user does not exist, which allows remote attackers to determine valid usernames via a timing attack.

Published: May 12, 2003; 12:00:00 AM -04:00
V2: 5.0 MEDIUM
CVE-2002-0765

sshd in OpenSSH 3.2.2, when using YP with netgroups and under certain conditions, may allow users to successfully authenticate and log in with another user's password.

Published: August 12, 2002; 12:00:00 AM -04:00
V2: 7.5 HIGH
CVE-2002-0639

Integer overflow in sshd in OpenSSH 2.9.9 through 3.3 allows remote attackers to execute arbitrary code during challenge response authentication (ChallengeResponseAuthentication) when OpenSSH is using SKEY or BSD_AUTH authentication.

Published: July 03, 2002; 12:00:00 AM -04:00
V2: 10.0 HIGH
CVE-2002-0640

Buffer overflow in sshd in OpenSSH 2.3.1 through 3.3 may allow remote attackers to execute arbitrary code via a large number of responses during challenge response authentication when OpenBSD is using PAM modules with interactive keyboard authentication (PAMAuthenticationViaKbdInt).

Published: July 03, 2002; 12:00:00 AM -04:00
V2: 10.0 HIGH
CVE-2002-0575

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.

Published: June 18, 2002; 12:00:00 AM -04:00
V2: 7.5 HIGH
CVE-2002-0083

Off-by-one error in the channel code of OpenSSH 2.0 through 3.0.2 allows local users or remote malicious servers to gain privileges.

V2: 10.0 HIGH
CVE-2001-1507

OpenSSH before 3.0.1 with Kerberos V enabled does not properly authenticate users, which could allow remote attackers to login unchallenged.

Published: December 31, 2001; 12:00:00 AM -05:00

CVE-2001-1585

SSH protocol 2 (aka SSH-2) public key authentication in the development snapshot of OpenSSH 2.3.1, available from 2001-01-18 through 2001-02-08, does not perform a challenge-response step to ensure that the client has the proper private key, which allows remote attackers to bypass authentication as other users by supplying a public key from that user's authorized_keys file.
