Overview

Bind vulnerability


Packages

Details

It was discovered that Bind did not properly perform signature verification.
When DNSSEC with DSA signatures are in use, a remote attacker could exploit
this to bypass signature validation to spoof DNS entries and poison DNS
caches. Among other things, this could lead to misdirected email and web
traffic.
