Buffer overflow protection refers to various techniques used during software development to enhance the security of executable programs by detecting buffer overflows on stack-allocated variables as they occur and preventing them from becoming serious security vulnerabilities. There have been several implementations of buffer overflow protection.
This article deals with stack-based overflow; similar protections also exist against heap-based overflows, but they are implementation-specific.

Famous quotes containing the words overflow and/or protection:
“A man’s interest in the world is only the overflow from his interest in himself. When you are a child your vessel is not yet full; so you care for nothing but your own affairs. When you grow up, your vessel overflows; and you are a politician, a philosopher, or an explorer and adventurer. In old age the vessel dries up: there is no overflow: you are a child again.”
—George Bernard Shaw (1856–1950)
“Without infringing on the liberty we so much boast, might we not ask our professional Mayor to call upon the smokers, have them register their names in each ward, and then appoint certain thoroughfares in the city for their use, that those who feel no need of this envelopment of curling vapor, to insure protection may be relieved from a nuisance as disgusting to the olfactories as it is prejudicial to the lungs.”
—Harriot K. Hunt (1805–1875)
