AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2025-14935 is a heap-based buffer overflow vulnerability in NSF Unidata's NetCDF-C library. It occurs during the parsing of dimension names due to improper validation of the length of user-supplied data before copying it into a fixed-length heap buffer. Exploiting this flaw requires user interaction, such as visiting a malicious webpage or opening a crafted file. Successful exploitation allows remote attackers to execute arbitrary code with the privileges of the current user. [1]
How can this vulnerability impact me? :
This vulnerability can allow remote attackers to execute arbitrary code on affected systems with the privileges of the current user. This can lead to full compromise of confidentiality, integrity, and availability of the system, potentially resulting in data theft, data corruption, or denial of service. [1]
