"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by a vulnerability as referenced in the
ALINUX3-SA-2025:0062 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2025-31498:
    c-ares is an asynchronous resolver library. From 1.32.3 through 1.34.4, there is a use-after-free in
    read_answers() when process_answer() may re-enqueue a query either due to a DNS Cookie Failure or when the
    upstream server does not properly support EDNS, or possibly on TCP queries if the remote closed the
    connection immediately after a response. If there was an issue trying to put that new transaction on the
    wire, it would close the connection handle, but read_answers() was still expecting the connection handle
    to be available to possibly dequeue other responses. In theory a remote attacker might be able to trigger
    this by flooding the target with ICMP UNREACHABLE packets if they also control the upstream nameserver and
    can return a result with one of those conditions, this has been untested. Otherwise only a local attacker
    might be able to change system behavior to make send()/write() return a failure condition. This
    vulnerability is fixed in 1.34.5.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
