"The remote EulerOS host is missing multiple security updates.");
  script_set_attribute(attribute:"description", value:
"According to the versions of the curl packages installed, the EulerOS installation on the remote host is affected by the
following vulnerabilities :

    When asked to both use a `.netrc` file for credentials and to follow HTTP redirects, curl could leak the
    password used for the first host to the followed-to host under certain circumstances.This flaw only
    manifests itself if the netrc file has an entry that matches the redirect target hostname but the entry
    either omits just the password or omits both login and password.(CVE-2024-11053)

    When libcurl is asked to perform automatic gzip decompression of content-encoded HTTP responses with the
    `CURLOPT_ACCEPT_ENCODING` option,**using zlib 1.2.0.3 or older**, an attacker-controlled integer overflow
    would make libcurl perform a buffer overflow.(CVE-2025-0725)

    When asked to use a `.netrc` file for credentials **and** to follow HTTP redirects, curl could leak the
    password used for the first host to the followed-to host under certain circumstances.This flaw only
    manifests itself if the netrc file has a `default` entry that omits both login and password. A rare
    circumstance.(CVE-2025-0167)

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

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