Adobe Flash exploit to be patched next
week
by Darren Allan
Adobe has issued a warning that a critical vulnerability has been detected in
its Flash player.
The vulnerability is exploited via a corrupt Flash file packaged inside a
Microsoft Excel file. Apparently the XLS file sets up the system memory to make
the attack more effective, and with success it installs persistent malware on
the target machine.
