TITLE

Debian Security Advisory 4752-1

DESCRIPTION

In BIND 9.0.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.9.3-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker on the network path for a TSIG-signed request, or operating the server receiving the TSIG-signed request, could send a truncated response to that request, triggering an assertion failure, causing the server to exit. Alternately, an off-path attacker would have to correctly guess when a TSIG-signed request was sent, along with other characteristics of the packet and message, and spoof a truncated response to trigger an assertion failure, causing the server to exit. runc is a CLI (command line interface) tool for building and running containers according to the OCI specification. BIND 9.0.0 to 9.11.21, 9.12.0 to 9.16.5, 9.17.0 to 9.17.3, 9.9.3-S1 to 9.11.21-S1 have security vulnerabilities, attackers can construct a special request to cause an assertion failure Causes the target service to end abnormally. For the stable distribution (buster), these problems have been fixed in version 1:9.11.5.P4+dfsg-5.1+deb10u2. We recommend that you upgrade your bind9 packages.
