Microsoft warned that a previously reported flaw of Apple Safari can be combined with a flaw in Internet Explorer to run unauthorized program on users’ computers.
The Apple Safari’s flaw, reported since May 15th, could allow a malicious web site to download any executable to the user’s Desktop without consent and this wrong behavior can be linked to a Microsoft Internet Explorer’s flaw that mishandle executables located on the Desktop allowing to run them, still without the user consent.
