Title
Hancom Office Show PPT File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability
Summary
Hancom Office Show PPT File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Hancom Office Show. 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 parsing of PPT files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-20387.

CVE-2017-2819 (GCVE-0-2017-2819)
Vulnerability from nvd – Published: 2017-05-24 14:00 – Updated: 2024-08-05 14:02
VLAI
Summary
An exploitable heap-based buffer overflow exists in the Hangul Word Processor component (version 9.6.1.4350) of Hancom Thinkfree Office NEO 9.6.1.4902. A specially crafted document stream can cause an integer underflow resulting in a buffer overflow which can lead to code execution under the context of the application. An attacker can entice a user to open up a document in order to trigger this vulnerability.
Severity
8.8 (High)

Title
Hancom Office Word DOC File Parsing Use-After-Free Remote Code Execution Vulnerability
Summary
Hancom Office Word DOC File Parsing Use-After-Free Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Hancom Office Word. 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 parsing of DOC files. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-20384.

Hancom Office Show PPT File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability
Summary
Hancom Office Show PPT File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Hancom Office Show. 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 parsing of PPT files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-20387.

Title
Hancom Office Cell XLS File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability
Summary
Hancom Office Cell XLS File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Hancom Office Cell. 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 parsing of XLS files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-20386.
