Cache poisoning

Cache poisoning refers to a computer security vulnerability where invalid entries can be placed into a cache, which are then assumed to be valid when later used. Two common varieties are DNS cache poisoning and ARP cache poisoning. Web cache poisoning involves the poisoning of web caches. Attacks on other, more specific, caches also exist.

Cache poisoning refers to a computer security vulnerability where invalid entries can be placed into a cache, which are then assumed to be valid when later used.1 Two common varieties are DNS cache poisoning2 and ARP cache poisoning. Web cache poisoning involves the poisoning of web caches3 (which has led to security issues in programming languages, including all Python versions at the time in 2021, and expedited security updates4). Attacks on other, more specific, caches also exist.567
