Why it matters this month
Threats in SecurityTabs news using techniques this control mitigates.
Weaknesses it helps against
Through the techniques typically used to exploit them (CTID, CISA KEV).
- CWE-1193 techniquesImproper Restriction of Operations within the Bounds of a Memory BufferCode reads or writes past the end of a buffer, the root of most classic memory-corruption exploits.
- CWE-1203 techniquesBuffer Copy without Checking Size of Input ('Classic Buffer Overflow')Input is copied into a fixed-size buffer without checking its length, overwriting whatever follows.
- CWE-1213 techniquesStack-based Buffer OverflowAn overflow on the stack can overwrite the return address and redirect the program to attacker code.
- CWE-1223 techniquesHeap-based Buffer OverflowAn overflow on the heap corrupts neighbouring objects, often turned into code execution.
- CWE-203 techniquesImproper Input ValidationInput isn't checked against what the program expects; the umbrella cause behind many specific flaws.
- CWE-4163 techniquesUse After FreeThe program keeps using memory after releasing it, so an attacker who controls what lands there next can hijack execution.
- CWE-6933 techniquesProtection Mechanism FailureA security feature exists but can be bypassed or doesn't engage when it should.
- CWE-793 techniquesImproper Neutralization of Input During Web Page Generation ('Cross-site Scripting')Input is echoed into a web page as script, running in other users' browsers with their session.
- CWE-3462 techniquesOrigin Validation ErrorThe software doesn't verify where a message really came from, so forged messages are trusted.
- CWE-8432 techniquesAccess of Resource Using Incompatible Type ('Type Confusion')An object is treated as the wrong type; a favourite in browser and JavaScript-engine exploits.
