CVE-2021-21493: SAP 3D Visual Enterprise Viewer GIF File Parsing Memory Corruption Remote Code Execution Vulnerability
This vulnerability allows remote attackers to disclose sensitive information on affected installations of SAP 3D Visual Enterprise Viewer. 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 GIF files. The issue results from the lack of proper validation of user-supplied data, which can result in 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.
