Deep dives, practical guides, and incident analyses from engineers who build Safeguard. No fluff, no vendor FUD — just what you need to ship secure software.
Closing a file twice, unlocking twice or decoding twice can corrupt state or bypass filters. See the cases MITRE lists and how to guarantee single use.
Recursive code with no depth limit lets a crafted input exhaust the stack or memory. See the real cases MITRE lists and how to bound recursion.
When outsiders can change which files, libraries or paths a program trusts, its own boundaries stop meaning anything.
Using a handle, token, session or memory block after it has been released leads to crashes and data leaks. Patterns, detection and fixes.
Hard-coded accounts and settings an admin cannot change leave customers unable to defend their own deployments.
Some logic is wrong every time it runs, not just under attack. A missing brace, a wrong branch or a fatal error where an error code belongs.
Names like CON, AUX and PRN are not files. If user input becomes a path, they can crash a server or expose errors. Here is how to handle CWE-67.
Trusting an update, an upload or a file just because it crossed a boundary gives attackers control. See the CVEs MITRE cites and how to verify what you import.
Files, services and data end up reachable by people who should never touch them. Learn the control sphere idea and how to test your own boundaries.
