Description

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Flash. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the TextFormat objects. By manipulating the tabStops property of a TextFormat object, an attacker can force a dangling pointer to be reused after it has been freed. An attacker can leverage this vulnerability to execute arbitrary code under the context of the current process.
