Zero-day exploit actively being abused.
Adobe
has
announced
it will release an update for its
Flash Player
on Friday 15 April, fixing a vulnerability that is currently being exploited.
The vulnerability, which affects
Flash Player 10.2.x
on
Windows
,
Macintosh
,
Linux
and
Solaris
, can be used by attackers to take control of an infected system. It is currently being used via Flash embedded in malicious websites and in
Microsoft Word
documents. In the latter case, spam messages – usually referring to the Fukushima nuclear disaster – arrive with a
Word
file attached. On opening the file, the Flash code is executed and, after allowing remote access for the attacker, the document is replaced by a clean version to avoid detection.
Though different in details, a similar vulnerability was used in the targeted
attack
on security company
RSA
last month, where employees received
Excel
documents with embedded Flash.
An analysis of the exploit can be found at the
Microsoft Malware Protection Center
blog
