Adobe has fixed a vulnerability in its widely used
document-viewing program Reader, but the firm is not revealing the
details of the security flaw.
Because of this, security analysts believe the flaw is serious,
and that users should update their systems to the
new version - version 8.1.2 - as soon as possible.
The flaw affects
PDF documents, which have been at the centre of previous critical
security threats involving Windows-based machines.
It is estimated that two-thirds of home users have the free
Adobe Reader software on their desktops, to enable them to read PDF
documents, so the implications of an unpatched machine could be
severe.
