SUSE SLED15 / SLES15 Security Update : bind (SUSE-SU-2021:1826-1)

high Nessus Plugin ID 150215



The remote SUSE host is missing one or more security updates.


This update for bind fixes the following issues :

CVE-2021-25214: Fixed a broken inbound incremental zone update (IXFR) which could have caused named to terminate unexpectedly (bsc#1185345).

CVE-2021-25215: Fixed an assertion check which could have failed while answering queries for DNAME records that required the DNAME to be processed to resolve itself (bsc#1185345).

Switched from /var/run to /run (bsc#1185073)

Hardening: Compiled binary with PIE flags to make it position independent

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
