(IBM Issues Fix for IBM Security Access Manager Appliance) OpenSSH Multiple Flaws Let Remote Authenticated Users Gain Elevated Privileges and Local Privileged Users Obtain Host Private Keys
SecurityTracker Alert ID:  1040165
SecurityTracker URL:  http://securitytracker.com/id/1040165
CVE Reference:   CVE-2016-10009   (Links to External Site)
Date:  Jan 12 2018
Impact:   Denial of service via network, Disclosure of authentication information, Execution of arbitrary code via network, Modification of system information, Modification of user information, Root access via local system, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 9.0.3, 9.0.3.1
Description:   Multiple vulnerabilities were reported in OpenSSH. A remote authenticated user can gain elevated privileges. A remote authenticated user can write files on the target system. A local user can obtain private keys on the target system. IBM Security Access Manager Appliance is affected.

A remote authenticated user with control of a sshd service can return a request to the target ssh-agent to load a specially crafted PKCS#11 module across a forwarded agent channel and execute arbitrary code on or write files to the target system running the ssh-agent [CVE-2016-10009].

A user that can exploit a separate vulnerability on sshd may be able to gain root privileges via a forwarded Unix-domain socket [CVE-2016-10010]. Systems with privilege separation disabled are affected.

A local privileged user may be able to exploit a privilege separation flaw to obtain host private key material [CVE-2016-10011].

A user that can exploit a separate vulnerability on sshd may be able to gain elevated privileges due to a flaw in boundary checks in the shared memory manager that may be skipped by some optimizing compilers [CVE-2016-10012].

A remote user may be able to bypass address-based access controls if the AllowUser directive is configured with invalid CIDR address ranges.

Jann Horn of Project Zero, Guido Vranken, and Laurence Parry reported these vulnerabilities.

Impact:   A remote authenticated user can gain elevated privileges on the target system.

A remote authenticated user can modify files on the target system.

A local user can obtain passwords on the target system.

Solution:   IBM has issued a fix for CVE-2016-10009 for IBM Security Access Manager Appliance (APAR IJ01544).
