Summary

ISC BIND is prone to a denial of service (DoS) vulnerability.

Insight

Insight

Exploitation of broken authoritative servers using a flaw in response processing can cause degradation in BIND resolver performance. The way the lame cache is currently designed makes it possible for its internal data structures to grow almost infinitely, which may cause significant delays in client query processing.

Affected Software

Affected Software

BIND 9.3.0 through 9.11.35, 9.12.0 through 9.16.21, 9.9.3-S1 through 9.11.35-S1, 9.16.8-S1 through 9.16.21-S1 and 9.17.0 through 9.17.18. Authoritative-only BIND 9 servers are not vulnerable to this flaw.

Detection Method

Detection Method

Checks if a vulnerable version is present on the target host.

Solution

Update to version 9.11.36, 9.16.22, 9.17.19, 9.11.36-S1, 9.16.22-S1 or later.
