Summary

Stack-based buffer overflow in Microsoft Office Word 2000 SP3, 2002 SP3, 2003 SP3, and 2007 Gold and SP1; Word Viewer 2003 Gold and SP3; Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats Gold and SP1; and Microsoft Works 8 allow remote attackers to execute arbitrary code via a crafted Word document that contains a malformed table property, which triggers memory corruption, aka "Word Memory Corruption Vulnerability."

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

descriptionThe remote host is running a version of Microsoft Word that may allow arbitrary code to be run on this host. To succeed, the attacker would have to send a rogue file to a user of the remote computer and have him open it. Then a bug in the word record parsing handler would result in code execution.
