Advisory Content (Page 1 of 3)[ 1 ] [ 2 ] [ 3 ]

Description:
A vulnerability has been reported in Microsoft Windows Vista, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an improper implementation of SMBv2 signing and can be exploited to execute arbitrary code by spoofing the signature in a SMBv2 packet to a trusted host.

Successful exploitation requires e.g. that SMBv2 is enabled (not enabled by default unless required by a host) and that SMBv2 is used in the communications (not used when e.g. one system is a previous operating system version).
