CVE-2020-8869
Description
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit Studio Photo 3.6.6.916. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of TIF files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-9881.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
A stack-based buffer overflow in Foxit Studio Photo 3.6.6.916 when parsing TIF files allows remote code execution with user interaction.
Vulnerability
A stack-based buffer overflow vulnerability exists in Foxit Studio Photo version 3.6.6.916 when handling TIF files. The issue stems from improper validation of the length of user-supplied data before copying it to a fixed-length stack-based buffer, leading to a buffer overflow [2].
Exploitation
An attacker can exploit this vulnerability by convincing a user to open a malicious TIF file or visit a malicious page hosting the file. No special privileges or network access beyond the initial user interaction are required [2]. The user must open the file with Foxit Studio Photo for the exploit to trigger.
Impact
Successful exploitation allows an attacker to execute arbitrary code within the context of the current process, potentially leading to full compromise of the affected system with high confidentiality, integrity, and availability impact [2].
Mitigation
As of the publication date, no official security update or patch has been released by Foxit Software for this vulnerability in Foxit Studio Photo [1]. Users should exercise caution when opening TIF files from untrusted sources and consider using alternative software until a fix is available.
