SUSE: CVE-2015-5600: SUSE Linux Security Advisory

Severity CVSS Published Added Modified
9 (AV:N/AC:L/Au:N/C:P/I:N/A:C) August 02, 2015 December 18, 2015 September 14, 2018

Description

The kbdint_next_device function in auth2-chall.c in sshd in OpenSSH through 6.9 does not properly restrict the processing of keyboard-interactive devices within a single connection, which makes it easier for remote attackers to conduct brute-force attacks or cause a denial of service (CPU consumption) via a long and duplicative list in the ssh -oKbdInteractiveDevices option, as demonstrated by a modified client that provides a different password for each pam element on this list.
