TITLE

OpenSSH of PAM Vulnerability to timing attack in authentication

Trust: 0.8

sources: JVNDB: JVNDB-2003-000136

DESCRIPTION

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. Portable Edition OpenSSH If this setting is PAM If enabled in conjunction with an implementation of OpenSSH When authentication fails, the authentication result is determined depending on the existing username and non-existing username. "Permission denied, please try again." There is a vulnerability where there is a difference in the time it takes to return the .It may be possible to guess whether the username exists or not. The portable version of OpenSSH is reported prone to an information-disclosure vulnerability. The portable version is distributed for operating systems other than its native OpenBSD platform. This issue is related to BID 7467. Reportedly, the previous fix for BID 7467 didn't completely fix the issue. This current issue may involve differing code paths in PAM, resulting in a new vulnerability, but this has not been confirmed. Exploiting this vulnerability allows remote attackers to test for the presence of valid usernames. Knowledge of usernames may aid them in further attacks
