Adobe has released an advisory for Flash Player 10.1.82.76 and earlier versions for Windows, Macintosh, Linux, Solaris, and Adobe Flash Player 10.1.92.10 for Android, as well as Adobe Reader 9.3.4 for Windows, Macintosh and UNIX, and Adobe Acrobat 9.3.4 and earlier versions for Windows and Macintosh. CVE-2010-2884 has been assigned to the issue, which has an impact of crashing Flash or arbitrary code execution on some affected platforms. There is currently no patch, Adobe has indicated that it should be released in late September and/or early October. There are indications that this previously unknown vulnerability is currently being exploited in the wild by malicious web sites attacking browsers. YYAAAV Yes, Yet Again Another Adobe Vulnerability. Sigh.

Keep an eye out for this one folks. It will take a bit for the anti-virus, IDS/IPS and other vendors to catch up and detect the malware that exploits the vulnerability. Although by that point the box affected may well be compromised as most detect after the exploit has already taken place. Since the vendor has released the advisory after being notified that exploits are already occurring against Windows boxes it is recommended to explore workarounds for mitigation, detection of already compromised hosts, and cleanup.
