"According to the versions of the golang packages installed, the EulerOS installation on the remote host is affected by
the following vulnerabilities :

    If the PATH environment variable contains paths which are executables (rather than just directories),
    passing certain strings to LookPath ('', '.', and '..'), can result in the binaries listed in the PATH
    being unexpectedly returned.(CVE-2025-47906)

    Cancelling a query (e.g. by cancelling the context passed to one of the query methods) during a call to
    the Scan method of the returned Rows can result in unexpected results if other queries are being made in
    parallel. This can result in a race condition that may overwrite the expected results with those of
    another query, causing the call to Scan to return either unexpected results from the other query or an
    error.(CVE-2025-47907)

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

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