CVE-2003-0190 is an observable timing discrepancy in OpenSSH-portable/OpenSSH 3.6.1p1 and earlier when PAM support is enabled. During authentication, the affected implementation immediately returns an error when the supplied username does not exist. This behavior is measurably distinguishable from processing for an existing account, allowing an unauthenticated remote party to determine whether usernames are valid through repeated timing measurements.
