Improper Restriction of Operations within the Bounds of a Memory Buffer

CVE-2009-1129

High
9.3/10

Summary

Multiple stack-based buffer overflows in the PowerPoint 95 importer (PP7X32.DLL) in Microsoft Office PowerPoint 2000 SP3, 2002 SP3, and 2003 SP3 allow remote attackers to execute arbitrary code via an inconsistent record length in sound data in a file that uses a PowerPoint 95 (PPT95) native file format, aka "PP7 Memory Corruption Vulnerability," a different vulnerability than CVE-2009-1128.

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.
