"The remote host is affected by the vulnerability described in GLSA-202501-08 (Qt: Buffer Overflow)

    When given specifically crafted data then QXmlStreamReader can end up causing a buffer overflow and
    subsequently a crash or freeze or get out of memory on recursive entity expansion, with DTD tokens in XML
    body.

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

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