Title: | DSA-3097-1 -- unbound security update | ||
Description: | Florian Maury from ANSSI discovered that unbound, a validating, recursive, and caching DNS resolver, was prone to a denial of service vulnerability. An attacker crafting a malicious zone and able to emit (or make emit) queries to the server can trick the resolver into following an endless series of delegations, leading to resource exhaustion and huge network usage. | ||
