FreeBSD : NSD -- multiple vulnerabilities (bac88b3f-c8a1-11f1-866a-3c7c3fba4204)

high Nessus Plugin ID 366447

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the bac88b3f-c8a1-11f1-866a-3c7c3fba4204 advisory.

NLnet Labs reports:
This security release has fixes for vulnerabilities which were all for cases with specially crafted and formatted data in zone files. Zone files which are written out by NSD itself, such as for zones for which NSD is secondary, would not be formatted like this. The zone file had to be fed to NSD directly, but could in multi-tenant configurations, come from an operator controlled provisioning system accessible to third parties. Zone files that are regularly formatted (generated from DNS software) or come from trusted sources would not trigger these vulnerabilities.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

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

Solution

Update the affected packages.
