Slackware Linux 15.0 / current bind Vulnerability (SSA:2023-172-01)

high Nessus Plugin ID 177532

Language:

Synopsis

The remote Slackware Linux host is missing a security update to bind.

Description

The version of bind installed on the remote host is prior to 9.16.42 / 9.18.16. It is, therefore, affected by a vulnerability as referenced in the SSA:2023-172-01 advisory.

- If the `recursive-clients` quota is reached on a BIND 9 resolver configured with both `stale-answer-enable yes;` and `stale-answer-client-timeout 0;`, a sequence of serve-stale-related lookups could cause `named` to loop and terminate unexpectedly due to a stack overflow. This issue affects BIND 9 versions 9.16.33 through 9.16.41, 9.18.7 through 9.18.15, 9.16.33-S1 through 9.16.41-S1, and 9.18.11-S1 through 9.18.15-S1.
(CVE-2023-2911)

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

Solution

Upgrade the affected bind package.
