Exploitability
| CWE ID | Description |
|---|---|
| CWE-120 | The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer. |
| CWE-119 | The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2025-34106 is a buffer overflow vulnerability in PDF Shaper versions 3.5 and 3.6 that occurs when converting a specially crafted PDF file to an image using the 'Convert PDF to Image' feature. An attacker can exploit this by tricking a user into opening a malicious PDF, causing the software to overflow a buffer and potentially execute arbitrary code with the user's privileges. This affects Windows XP, 7, 8, and 10 platforms and involves the PDFTools.exe component. [1, 2, 3]
How can this vulnerability impact me? :
This vulnerability can lead to arbitrary code execution on your system if you open a maliciously crafted PDF file with the vulnerable PDF Shaper software. An attacker could gain control over your system under your user context, potentially compromising confidentiality, integrity, and availability of your data and system resources. [1, 2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by identifying if PDF Shaper versions 3.5 or 3.6 are installed and if the 'Convert PDF to Image' functionality is used. Detection can also involve scanning for the presence of maliciously crafted PDF files designed to exploit the buffer overflow. Since the exploit is local and requires user interaction, monitoring for suspicious PDF files or unusual activity related to PDFTools.exe may help. Specific commands are not provided in the resources, but using antivirus or endpoint detection tools to scan for the known Metasploit module (EDB-37760) or monitoring file creation/opening events related to PDF Shaper could be useful. [1, 2, 3]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include avoiding opening PDF files from untrusted sources using PDF Shaper versions 3.5 and 3.6, especially the 'Convert PDF to Image' feature. Restrict local access to systems running these versions to trusted users only. If possible, update or patch PDF Shaper to a version that addresses this vulnerability (though no patch information is provided). Additionally, disabling or restricting the use of the PDFTools.exe component or the conversion feature until a fix is available can reduce risk. [1, 2]
