Slackware 14.x: 2020-234-01 Critical: Bind Security Update

slackware
Calendar Grey August 21, 2020
Dist Slackware Esm H88
Recent updates have been released for Slackware, aimed at resolving vulnerabilities linked to subdomain configurations and assertion failures.
New bind packages are available for Slackware 14.0, 14.1, 14.2, and -current to fix security issues

Summary

Here are the details from the Slackware 14.2 ChangeLog: patches/packages/bind-9.11.22-i586-1_slack14.2.txz: Upgraded. This update fixes three security issues: "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. 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. It was possible to trigger an assertion failure when verifying the response to a TSIG-signed request.
