memory overflow

About this tag
Memory overflow vulnerabilities are a recurring security concern discussed on WindowsForum, covering issues in both software libraries and critical infrastructure. Recent threads highlight a heap overflow in KissFFT (CVE-2025-34297) affecting 32-bit builds, a memory overflow in Citrix NetScaler ADC and Gateway (CVE-2025-7775) enabling pre-auth remote code execution, and a critical Windows Graphics Component flaw (CVE-2025-49742) that also involves memory handling. Additionally, memory overflow issues have been reported in Hitachi Energy's Relion and SAM600-IO devices used in power grid systems. These discussions emphasize the importance of patching and understanding memory overflow risks across diverse platforms.
