[ASA-201810-10] libssh: authentication bypass
Arch Linux Security Advisory ASA-201810-10 ========================================== Severity: Critical Date : 2018-10-17 CVE-ID : CVE-2018-10933 Package : libssh Type : authentication bypass Remote : Yes Link : https://security.archlinux.org/AVG-780 Summary ======= The package libssh before version 0.8.4-1 is vulnerable to authentication bypass. Resolution ========== Upgrade to 0.8.4-1. # pacman -Syu "libssh>=0.8.4-1" The problem has been fixed upstream in version 0.8.4. Workaround ========== None. Description =========== An authentication bypass vulnerability has been discovered in libssh versions prior to 0.7.6 and 0.8.4, in the server-side state machine. By presenting the server an SSH2_MSG_USERAUTH_SUCCESS message in place of the SSH2_MSG_USERAUTH_REQUEST message which the server would expect to initiate authentication, the attacker could successfully authenticate without any credentials, resulting in unauthorized access. Impact ====== A remote attacker is able to successfully authenticate without any credentials, resulting in unauthorized access.
