Exploitability
| CWE ID | Description |
|---|---|
| CWE-190 | The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a remote code execution flaw in NSF Unidata's NetCDF-C library. It occurs because the software does not properly validate user-supplied data when parsing NC variables, which can cause an integer overflow before allocating memory. An attacker can exploit this by tricking a user into visiting a malicious webpage or opening a malicious file, allowing the attacker to run arbitrary code with the same privileges as the current user. [1]
How can this vulnerability impact me? :
If exploited, this vulnerability allows an attacker to execute arbitrary code on your system with the privileges of the current user. This could lead to unauthorized actions such as data theft, system compromise, or further attacks within your environment, especially if the user has elevated privileges. [1]
