QID 15134: ISC BIND Buffer Overflow Vulnerability (CVE-2022-3094)

ISC BIND (Berkley Internet Domain Name) is an implementation of DNS protocols.

Memory is allocated prior to the checking of access permissions (ACLs) and is retained during the processing of a dynamic update from a client whose access credentials are accepted. Memory allocated to clients that are not permitted to send updates is released immediately upon rejection. The scope of this vulnerability is limited therefore to trusted clients who are permitted to make dynamic zone changes. Affected software:
BIND 9.16.0 - 9.16.36
BIND 9.18.0 - 9.18.10
BIND 9.19.0 - 9.19.8
BIND 9.16.8-S1 - 9.16.36-S1

Patched Versions:
BIND 9.16.37
BIND 9.18.11
BIND 9.19.9
