Description
An Out-of-bounds Read vulnerability exists in Open Design Alliance ODA Viewer before 2022.8. Crafted data in a DWF file can trigger a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
ODA Viewer before 2022.8 has an out-of-bounds read in DWF file parsing, potentially allowing arbitrary code execution via crafted files.
Vulnerability
An out-of-bounds read vulnerability exists in Open Design Alliance (ODA) Viewer versions prior to 2022.8 [1]. The flaw occurs when parsing crafted DWF files, causing a read past the end of an allocated buffer. The vulnerability is present in the DWF file handling code.
Exploitation
An attacker can exploit this by providing a specially crafted DWF file to a user of ODA Viewer. No authentication is required; the user must open the malicious file. The attacker can leverage this out-of-bounds read in conjunction with other vulnerabilities to achieve code execution [1].
Impact
Successful exploitation could allow an attacker to execute arbitrary code in the context of the current process. This could lead to full compromise of the affected system, including data theft or further malware installation [1].
Mitigation
The vulnerability is fixed in ODA Viewer version 2022.8 [1]. Users should update to this version or later. No workarounds are mentioned. The vulnerability is not listed on CISA's Known Exploited Vulnerabilities catalog as of the publication date.
