SUSE SLES11 Security Update : bind (SUSE-SU-2021:14632-1)

high Nessus Plugin ID 150654

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES11 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2021:14632-1 advisory.

- BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG features. In a configuration which uses BIND's default settings the vulnerable code path is not exposed, but a server can be rendered vulnerable by explicitly setting valid values for the tkey-gssapi-keytab or tkey-gssapi-credentialconfiguration options. Although the default configuration is not vulnerable, GSS- TSIG is frequently used in networks where BIND is integrated with Samba, as well as in mixed-server environments that combine BIND servers with Active Directory domain controllers. The most likely outcome of a successful exploitation of the vulnerability is a crash of the named process. However, remote code execution, while unproven, is theoretically possible. Affects: BIND 9.5.0 -> 9.11.27, 9.12.0 -> 9.16.11, and versions BIND 9.11.3-S1 -> 9.11.27-S1 and 9.16.8-S1 -> 9.16.11-S1 of BIND Supported Preview Edition.
Also release versions 9.17.0 -> 9.17.1 of the BIND 9.17 development branch (CVE-2020-8625)

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.
