Xlnt Vulnerabilities

This vulnerability allows an attacker to crash the xlnt application by causing it to access a part of memory that doesn't exist, leading to a program failure. The attacker must have local access to the system to exploit this issue, and there are publicly available methods to do so.

This vulnerability allows an attacker to read sensitive data from memory by manipulating how the software processes encrypted XLSX files. However, the attack can only be carried out locally, meaning the attacker needs access to the system where the software is running.

This vulnerability allows an attacker with local access to read beyond the intended limits of memory in the xlnt XLSX file parser, potentially exposing sensitive information. It is important to apply the provided patch to fix this issue, as the exploit has already been made public.
