Horizon Alert
Summary of the vulnerability and why it matters
Microsoft Office PowerPoint is vulnerable to memory corruption when processing a specially crafted PowerPoint file. This flaw can allow an attacker to execute arbitrary code, potentially leading to unauthorized system access and data compromise. The vulnerability affects specific versions of Microsoft Office PowerPoint, including those for Windows and Mac.
- Vulnerable: Microsoft Office PowerPoint
- Flaw: Memory corruption via invalid index
- Impact: Arbitrary code execution
Attack Path
How an attacker could exploit the issue
A specially crafted PowerPoint file can lead to memory corruption, enabling attackers to execute arbitrary code. This occurs when a PowerPoint file contains an `OutlineTextRefAtom` with an invalid index value. The vulnerability was known to be exploited in the wild as of April 2009.
- Malicious file exposure.
- Attacker delivers malicious file.
- Triggering corruption and code execution.
Live Threat
Current exploitation, exposure, and threat context
