Another day of Adobe being awesome at software.
Interesting that it was a vulnerability reported by Lockheed Martin CIRT.
This U3D memory corruption vulnerability (CVE-2011-2462) could cause a crash and potentially allow an attacker to take control of the affected system. There are reports that the vulnerability is being actively exploited in the wild in limited, targeted attacks against Adobe Reader 9.x on Windows. Adobe Reader X Protected Mode and Acrobat X Protected View mitigations would prevent an exploit of this kind from executing.
Also, there is an Adobe PSIRT you can subscribe to, though they don’t seem to post every vulnerability they address. I guess that would take a lot of bloggers.
