samba: crash in dcesrv_auth_bind_ack due to missing error check

Multiple flaws were found in Samba's DCE/RPC protocol implementation. A remote, authenticated attacker could use these flaws to cause a denial of service against the Samba server high CPU load or a crash or, possibly, execute arbitrary code with the permissions of the user running Samba root. Thi...

Microsoft Windows RPC Downgrade CVE-2016-0128 Man in the Middle Security Bypass Vulnerability

Description Microsoft Windows is prone to a security-bypass vulnerability. Successfully exploiting this issue may allow attackers to gain elevated privileges and perform unauthorized actions by conducting a man-in-the-middle attack. This may lead to other attacks. Technologies Affected Microsoft...

Man in the middle attacks possible with NTLMSSP

Description There are several man in the middle attacks possible with NTLMSSP authentication. E.g. NTLMSSPNEGOTIATESIGN and NTLMSSPNEGOTIATESEAL can be cleared by a man in the middle. This was by protocol design in earlier Windows versions. Windows Server 2003 RTM and Vista RTM introduced a way t...
