Improper Restriction of Operations within the Bounds of a Memory Buffer
CVE-2009-0220
Summary
Multiple stack-based buffer overflows in the PowerPoint 4.0 importer (PP4X32.DLL) in Microsoft Office PowerPoint 2000 SP3, 2002 SP3, and 2003 SP3 allow remote attackers to execute arbitrary code via crafted formatting data for paragraphs in a file that uses a PowerPoint 4.0 native file format, related to (1) an incorrect calculation from a record header, or (2) an interget that is used to specify the number of bytes to copy, aka "Legacy File Format Vulnerability."

CWE-119 - Buffer Overflow
Buffer overflow attacks involve data transit and operations exceeding the restricted memory buffer, thereby corrupting or overwriting data in adjacent memory locations. Such overflow allows the attacker to run arbitrary code or manipulate the existing code to cause privilege escalation, data breach, denial of service, system crash and even complete system compromise. Given that languages such as C and C++ lack default safeguards against overwriting or accessing data in their memory, applications utilizing these languages are most susceptible to buffer overflows attacks.
