Recommended update for bind
This update for bind fixes the following issues:
Bind was updated to version 9.11.22
Note:
- bind is now more strict in regards to DNSSEC. If queries are not working, check for DNSSEC issues. For instance, if bind is used in a namserver forwarder chain, the forwarding DNS servers must support DNSSEC.
This upgrade also fixes the following security issues:
-
- [security] 'update-policy' rules of type 'subdomain' were incorrectly treated as 'zonesub' rules, which allowed keys used in 'subdomain' rules to update names outside of the specified subdomains. The problem was fixed by making sure 'subdomain' rules are again processed as described in the ARM. (CVE-2020-8624 bsc#1175443)
-
- [security] When BIND 9 was compiled with native PKCS#11 support, it was possible to trigger an assertion failure in code determining the number of bits in the PKCS#11 RSA public key with a specially crafted packet. (CVE-2020-8623 bsc#1175443)
-
- [security] It was possible to trigger an assertion failure when verifying the response to a TSIG-signed request. (CVE-2020-8622 bsc#1175443)
- Suppress warning message about missing file. (bsc#1092283, bsc#1127583, bsc#1094236, bsc#1173983) Added /etc/bind.keys to NAMED_CONF_INCLUDE_FILES in /etc/sysconfig/named.

Описание
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.
