Description
Unspecified vulnerability in Adobe Flash Player 10.2.154.13 and earlier on Windows, Mac OS X, Linux, and Solaris; 10.1.106.16 and earlier on Android; Adobe AIR 2.5.1 and earlier; and Authplay.dll (aka AuthPlayLib.bundle) in Adobe Reader and Acrobat 9.x through 9.4.2 and 10.x through 10.0.1 on Windows and Mac OS X, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via crafted Flash content, as demonstrated by a .swf file embedded in an Excel spreadsheet, and as exploited in the wild in March 2011.

Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
No fixed release is recorded for CVE-2011-0609 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
| Product | Fixed in | Advisory |
|---|---|---|
| Red Hat Enterprise Linux 6 Supplementary | flash-plugin-0:10.2.153.1-1.el6 | RHSA-2011:0372 |
