Slackware 14.x: 2022-215-04 Urgent: DNS Buffer Overflow Vulnerabilities

Here are the details from the Slackware 14.2 ChangeLog: patches/packages/bind-9.11.31-i586-1_slack14.2.txz: Upgraded. This update fixes bugs and the following security issues: A specially crafted GSS-TSIG query could cause a buffer overflow in the ISC implementation of SPNEGO. named crashed when a DNAME record placed in the ANSWER section during DNAME chasing turned out to be the final answer to a client query. Insufficient IXFR checks could result in named serving a zone without an SOA record at the apex, leading to a RUNTIME_CHECK assertion failure when the zone was subsequently refreshed. This has been fixed by adding an owner name check for all SOA records which are included in a zone transfer.
