Adobe Reader and Acrobat 9.x before 9.3.3, and 8.x before 8.2.3 on Windows and Mac OS X, allow attackers to execute arbitrary code via a PDF file with crafted Flash content, involving the newfunction (0x44) operator and an "invalid pointer vulnerability" that triggers memory corruption, a different vulnerability than CVE-2010-1285 and CVE-2010-2201.

• → The exploit triggers via the newfunction (0x44) SWF operator embedded in a PDF. Detect the 6-byte sequence 40 E8 D4 F1 FF 33 inside Flash content delivered within a PDF (flowbit ET.flash.pdf must be set).
• → The exploit embeds a crafted SWF (poc.swf) as a RichMedia annotation inside a PDF, activated on page-open (/Condition /PO). Inspect PDF RichMedia annotations containing embedded SWF files for the malicious newfunction opcode. ↗
• → CVE-2010-2168 specifically involves the newfunction (0x44) Flash operator causing an invalid pointer / memory corruption. Differentiate from CVE-2010-1285 (newclass 0x58) and CVE-2010-2201 (pushstring 0x2C / debugfile 0xF1). ↗

• · The Snort/ET rule requires the flowbit ET.flash.pdf to be set (i.e., a prior rule must have identified Flash content inside a PDF). Ensure the prerequisite flowbit-setting rule is active, otherwise this rule will not fire.
