Virtuozzo 7 : bind / bind-chroot / bind-devel / etc (VZLSA-2020-5011)

medium Nessus Plugin ID 144433


The remote Virtuozzo host is missing a security update.


The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:5011 advisory.

- bind: truncated TSIG response can lead to an assertion failure (CVE-2020-8622)

- bind: remotely triggerable assertion failure in pk11.c (CVE-2020-8623)

- bind: incorrect enforcement of update-policy rules of type subdomain (CVE-2020-8624)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Note that Tenable Network Security has attempted to extract the preceding description block directly from the corresponding Red Hat security advisory. Virtuozzo provides no description for VZLSA advisories. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected bind / bind-chroot / bind-devel / etc package.
