Slackware Linux 15.0 / current bind Vulnerability (SSA:2023-264-01)

high Nessus Plugin ID 181772

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 9.16.44 / 9.18.19. It is, therefore, affected by a vulnerability as referenced in the SSA:2023-264-01 advisory.

- The code that processes control channel messages sent to `named` calls certain functions recursively during packet parsing. Recursion depth is only limited by the maximum accepted packet size; depending on the environment, this may cause the packet-parsing code to run out of available stack memory, causing `named` to terminate unexpectedly. Since each incoming control channel message is fully parsed before its contents are authenticated, exploiting this flaw does not require the attacker to hold a valid RNDC key;
only network access to the control channel's configured TCP port is necessary. This issue affects BIND 9 versions 9.2.0 through 9.16.43, 9.18.0 through 9.18.18, 9.19.0 through 9.19.16, 9.9.3-S1 through 9.16.43-S1, and 9.18.0-S1 through 9.18.18-S1. (CVE-2023-3341)

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.
