DESCRIPTION:
Greg Linares has reported a vulnerability in BitDefender Online
Scanner, which can be exploited by malicious people to compromise a
user's system.
The vulnerability is caused due to an input validation error within
the OScan8.ocx / OScan81.ocx ActiveX control when handling arguments
passed to the "InitX()" method. This can be exploited to cause a
heap-based buffer overflow by prepending two "%" characters to the
argument of the affected method.
Successful exploitation allows execution of arbitrary code.
The vulnerability is reported in version 8.0. Other versions may also
be affected.
SOLUTION:
Update to the latest version (OScan82.ocx).
