Severity

medium5.3

CVSS measures technical severity, not the likelihood of an attack.

Known exploitation

Not listed in the checked CISA KEV catalog

Absence from CISA KEV does not rule out attacks.

Public exploit

Not established by this record

Missing evidence does not mean no public exploit exists.

Remediation

Source guidance available

Review the recorded instructions. Guidance may be a workaround rather than a fixed version.

What this means

Avahi-daemon uses a fixed source port for wide-area DNS queries, which may simplify attacks using malicious DNS responses. The issue affects Avahi versions less than 0.9-rc3. The impact is uncertain.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

Automatic dependency matching is unavailable for this record. Use the product evidence and publisher’s instructions to check your installation.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

Configure Avahi wide-area DNS queries to be forwarded through a local DNS resolver, such as systemd-resolved, rather than sent directly by Avahi. The local resolver provides source-port randomization and reduces the risk of forged DNS responses. Apply vendor fixes when they become available.
