QID 243189: Red Hat Update for unbound (RHSA-2024:1751)

The unbound packages provide a validating, recursive, and caching dns or dnssec resolver...Security Fix(es):

    a vulnerability was found in unbound due to incorrect default permissions, allowing any process outside the unbound group to modify the unbound runtime configuration.
    The default combination of the "control-use-cert: no" option with either explicit or implicit use of an ip address in the "control-interface" option could allow improper access.
    If a process can connect over localhost to port 8953, it can alter the configuration of unbound.service.
    This flaw allows an unprivileged local process to manipulate a running instance, potentially altering forwarders, allowing them to track all queries forwarded by the local resolver, and, in some cases, disrupting resolving altogether..
Affected Products:
    Red Hat enterprise linux for x86_64 8 x86_64.
    Red hat enterprise linux for ibm z systems 8 s390x.
    Red hat enterprise linux for power, little endian 8 ppc64le.
