Description:
Several vulnerabilities were reported in Windows Server Message Block. A remote user can cause denial of service conditions on the target system. A remote authenticated user can obtain potentially sensitive information on the target system. A remote authenticated user can execute arbitrary code on the target system. A local user can gain elevated privileges.
A remote authenticated user can send specially crafted data to the target Microsoft Server Message Block 1.0 (SMBv1) server to execute arbitrary code on the target system [CVE-2017-11780].
A remote user can send specially crafted SMB requests to cause the target system to crash [CVE-2017-11781].
A remote authenticated user can send a specially crafted packet to obtain potentially sensitive information on the target system [CVE-2017-11815].
A local anonymous user that can gain access to certain named pipes on a remote system that permit anonymous access can gain elevated privileges on the target system [CVE-2017-11782].
pesante (via Trend Micro's Zero Day Initiative) and Nicolas Joly of MSRC Vulnerabilities & Mitigations reported these vulnerabilities.
