GLSA-200609-11 : BIND: Denial of Service
medium Nessus Plugin ID 22356
Synopsis
The remote Gentoo host is missing one or more security-related patches.Description
The remote host is affected by the vulnerability described in GLSA-200609-11 (BIND: Denial of Service)Queries for SIG records will cause an assertion error if more than one SIG RRset is returned. Additionally, an INSIST failure can be triggered by sending multiple recursive queries if the response to the query arrives after all the clients looking for the response have left the recursion queue.
Impact :
An attacker having access to a recursive server can crash the server by querying the SIG records where there are multiple SIG RRsets, or by sending many recursive queries in a short time. The exposure can be lowered by restricting the clients that can ask for recursion. An attacker can also crash an authoritative server serving a DNSSEC zone in which there are multiple SIG RRsets.
Workaround :
There are no known workarounds at this time.
Solution
All BIND 9.3 users should update to the latest version:# emerge --sync # emerge --ask --oneshot --verbose '>=net-dns/bind-9.3.2-r4' All BIND 9.2 users should update to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-dns/bind-9.2.6-r4'
