Security vulnerabilities and automated fixes for security patch issues

A critical buffer overflow vulnerability was discovered and patched in the linenoise.c input library used by the ds4 CLI tool, where unchecked memcpy operations could allow attackers to overwrite adjacent memory regions. The fix adds proper bounds checking before memory copy operations, preventing potential heap and stack corruption. This vulnerability serves as a timely reminder of why input validation and buffer size verification remain essential disciplines in C programming.
A critical heap buffer overflow vulnerability was discovered and patched in the ndsrvp HAL filter routines, where multiple `memcpy` calls used computed sizes derived from image dimensions without validating they fit within destination buffers. An attacker supplying a crafted image could exploit this to corrupt heap memory, potentially achieving arbitrary code execution. This post breaks down how the vulnerability works, how it was fixed, and what developers can do to prevent similar issues.
