FreeBSD : PowerDNS -- Multiple vulnerabilities (0823ac26-6040-11f1-ba4a-50ebf6bdf8e9)

high Nessus Plugin ID 319306

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 0823ac26-6040-11f1-ba4a-50ebf6bdf8e9 advisory.

PowerDNS Team reports:
2025-07: Internal logic flaw in cache management can lead to a denial of service in Recursor When using views, queries sent using TCP Proxy Protocol will select the view according to the address of the proxy, rather than the address of the initial query. This can lead to wrong data being returned.
Missing escaping of special characters (such as $ or @) in DNS names received during an AXFR operation can lead to an incorrect (non-parseable) Bind backend configuration to be written, causing this backend to fail until manual operation is performed to fix the configuration.
Missing sanity checks of the answer to the initial SOA query, when running in auto-secondary mode and receiving a notification for an not-yet-known domain may cause the server to crash.
Multiple concurrency and locking defects in the GSS-TSIG code can lead to memory corruption due to accidental data structure sharing, which can in turn lead to a program crash.
Missing proper escaping of double-quote characters when computing labels will cause AXFR of a catalog zone with a member whose producer group option contains such a character to fail.

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.
