1 CVE-2001-1585 287 Bypass 2001-12-31 2010-06-24
6.8
None Remote Medium Not required Partial Partial Partial
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.

8 CVE-2001-1244 DoS 2001-07-07 2008-09-05
5.0
None Remote Low Not required None None Partial
Multiple TCP implementations could allow remote attackers to cause a denial of service (bandwidth and CPU exhaustion) by setting the maximum segment size (MSS) to a very small number and requesting large amounts of data, which generates more packets with less TCP-level data that amplify network traffic and consume more server CPU to process.

1.2
None Local High Not required None None Partial
