AlmaLinux 8 : bind (ALSA-2022:2092)

medium Nessus Plugin ID 161107

Synopsis

The remote AlmaLinux host is missing a security update.

Description

The remote AlmaLinux 8 host has packages installed that are affected by a vulnerability as referenced in the ALSA-2022:2092 advisory.

- In BIND 9.3.0 -> 9.11.35, 9.12.0 -> 9.16.21, and versions 9.9.3-S1 -> 9.11.35-S1 and 9.16.8-S1 -> 9.16.21-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.18 of the BIND 9.17 development branch, exploitation of broken authoritative servers using a flaw in response processing can cause degradation in BIND resolver performance. The way the lame cache is currently designed makes it possible for its internal data structures to grow almost infinitely, which may cause significant delays in client query processing. (CVE-2021-25219)

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

Solution

Update the affected packages.
