Adobe Flash Player 0-Day Exploit (Mar 17, 2011)


SonicWALL UTM Research team found reports of new 0-day vulnerability in Adobe Flash Player 10 and the “authplay.dll” file that ships with Adobe Reader and Acrobat X products.

Successful exploitation would allow for arbitrary code injection and execution with the privileges of the currently logged in user. Code injection that does not result in execution would terminate the application due to memory corruption.

The vulnerability has been assigned as CVE-2011-0609.
