TITLE: Macromedia Flash Player SWF File Handling Arbitrary Code Execution SECUNIA ADVISORY ID: SA17430 VERIFY ADVISORY: http://secunia.com/advisories/17430/ CRITICAL: Highly critical IMPACT: System access WHERE: >From remote SOFTWARE: Macromedia Flash Player 7.x http://secunia.com/product/2634/ Macromedia Flash Player 6.x http://secunia.com/product/773/ DESCRIPTION: eEye Digital Security has reported a vulnerability in Macromedia Flash Player, which can be exploited by malicious people to compromise a user's system. The vulnerability is caused due to missing validation of the frame type identifier that is read from a SWF file. This value is used as an index in Flash.ocx to reference an array of function pointers. This can be exploited via a specially crafted SWF file to cause the index to reference memory that are under the attackers control, which causes Flash Player to use attacker supplied values as function pointers. Successful exploitation allows execution of arbitrary code. The vulnerability has been reported in Flash Player version 7.0.19.0 and prior. SOLUTION: Update to Flash Player 8 (8.0.22.0) or apply Flash Player 7 update (7.0.61.0 or 7.0.60.0).
