What is CVE-2021-34858?

This vulnerability impacts installations of TeamViewer, enabling remote attackers to execute arbitrary code if a user visits a compromised webpage or opens a malicious file. The flaw is located in the parsing of TVS files, arising from inadequate validation of user-supplied input. This oversight can lead to reading beyond the end of an allocated data structure, allowing an attacker to execute code within the context of the affected process.
