Received this warning about Flash from CERT.
Note that if you're using Linux or Mac OS X you're safer than under Windows as the vulnerability only lets a remote user run with the privileges of the user executing Flash. Windows users typically run with administrative privileges. In any case, Flash is used so much online it's good to watch for that patch for your distro (or get the latest version directly from Adobe).

There are critical vulnerabilities in Adobe Flash player and related
software. Exploitation of these vulnerabilities could allow a remote,
unauthenticated attacker to execute arbitrary code or cause a denial
of service on a vulnerable system.
Adobe Security Bulletin APSB07-12 addresses vulnerabilities in Adobe
Flash Player and related software. Further information is available in
the US-CERT Vulnerability Notes database.
Several operating systems, including Microsoft Windows and Apple OS X,
have vulnerable versions of Flash installed by default. Systems with
Flash-enabled web browsers are vulnerable. To exploit these
vulnerabilities, an attacker could host a specially crafted Flash file
on a web site and convince a user to visit the site.
A remote, unauthenticated attacker could execute arbitrary code with
the privileges of the user, steal credentials, or create a
denial-of-service condition. If the user is logged on with
administrative privileges, the attacker could take complete control of
an affected system.
Check with your vendor for patches or updates. For information about a
specific vendor, please see the Systems Affected section in the
vulnerability notes or contact your vendor directly. If you get the
flash player from Adobe, see the Adobe Get Flash page for information
Users who are unable to apply the patch should disable Flash. Contact
your vendor or see the US-CERT Vulnerability Notes VU#110297,
VU#730785, or VU#138457 for more details.
