Description
NSF Unidata NetCDF-C Time Unit Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of NSF Unidata NetCDF-C. 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 time units. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-27273.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is a stack-based buffer overflow in NSF Unidata NetCDF-C that occurs during the parsing of time units. It happens because the software does not properly validate the length of user-supplied data before copying it into a fixed-length buffer. An attacker can exploit this by tricking a user into visiting a malicious webpage or opening a malicious file, which then allows the attacker to execute arbitrary code with the current user's privileges. [1]


How can this vulnerability impact me? :

If exploited, this vulnerability allows an attacker to execute arbitrary code on your system with the same privileges as the current user. This can lead to unauthorized actions such as data theft, system compromise, or further attacks within your environment. Exploitation requires user interaction, like visiting a malicious webpage or opening a malicious file. [1]


What immediate steps should I take to mitigate this vulnerability?

To mitigate this vulnerability, avoid opening untrusted files or visiting untrusted webpages that could exploit the flaw. Apply any available patches or updates from the vendor for NSF Unidata NetCDF-C. Additionally, restrict user privileges to limit the impact of potential exploitation. [1]
