CVE-2009-3955: Adobe acrobat vulnerability
Adobe · Acrobat
Adobe Reader and Acrobat 9.x before 9.3, and 8.x before 8.2 on Windows and Mac OS X, allows remote attackers to execute arbitrary code via a crafted JPC_MS_RGN marker in the Jp2c stream of a JpxDecode encoded data stream, which triggers an integer sign extension that bypasses a sanity check, leading to memory corruption.
