1 CVE-2012-0814 255 +Info 2012-01-27 2012-02-16
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.
2 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.
3 CVE-2008-5161 200 +Info 2008-11-19 2014-08-08
2.6
None Remote High Not required Partial None None
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.
4 CVE-2008-3259 200 +Info 2008-07-22 2014-08-08
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.
5 CVE-2006-5229 200 +Info 2006-10-10 2011-08-26
2.6
None Remote High Not required Partial None None
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.
6 CVE-2006-4304 DoS Exec Code Overflow +Info 2006-08-23 2008-09-05
10.0
Admin Remote Low Not required Complete Complete Complete
Buffer overflow in the sppp driver in FreeBSD 4.11 through 6.1, NetBSD 2.0 through 4.0 beta before 20060823, and OpenBSD 3.8 and 3.9 before 20060902 allows remote attackers to cause a denial of service (panic), obtain sensitive information, and possibly execute arbitrary code via crafted Link Control Protocol (LCP) packets with an option length that exceeds the overall length, which triggers the overflow in (1) pppoe and (2) ippp. NOTE: this issue was originally incorrectly reported for the ppp driver.
7 CVE-2003-1366 200 +Info 2003-12-31 2008-09-05
3.3
None Local Medium Not required Partial Partial None
chpass in OpenBSD 2.0 through 3.2 allows local users to read portions of arbitrary files via a hard link attack on a temporary file used to store user database information.
8 CVE-2003-0078 +Info 2003-03-03 2008-09-10
5.0
None Remote Low Not required Partial None None
ssl3_get_record in s3_pkt.c for OpenSSL before 0.9.7a and 0.9.6 before 0.9.6i does not perform a MAC computation if an incorrect block cipher padding is used, which causes an information leak (timing discrepancy) that may make it easier to launch cryptographic attacks that rely on distinguishing between padding and MAC verification errors, possibly leading to extraction of the original plaintext, aka the "Vaudenay timing attack."
9 CVE-2002-0701 +Info 2002-07-23 2008-09-10
2.1
None Local Low Not required Partial None None
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.
10 CVE-2001-0572 +Info 2001-08-22 2008-09-05
7.5
User Remote Low Not required Partial Partial Partial
The SSH protocols 1 and 2 (aka SSH-2) as implemented in OpenSSH and other packages have various weaknesses which can allow a remote attacker to obtain the following information via sniffing: (1) password lengths or ranges of lengths, which simplifies brute force password guessing, (2) whether RSA or DSA authentication is being used, (3) the number of authorized_keys in RSA authentication, or (4) the lengths of shell commands.
