Improper Restriction of Operations within the Bounds of a Memory Buffer
Buffer overflow in the GDI engine in Windows Live Messenger, as used for Windows MSN Live 8.1, allows user-assisted remote attackers to cause a denial of service (application crash or system crash) and possibly execute arbitrary code by placing a malformed file in a new folder under the Sharing Folders path, and triggering a synchronize operation through the Windows MSN Live online service, possibly related to extended file attributes and possibly related to an incomplete fix for MS07-046, as demonstrated by a (1) .jpg, (2) .gif, (3) .wmf, (4) .doc, or (5) .ico file.
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.
