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

    An attacker may cause an HTTP/2 endpoint to read arbitrary amounts of header data by sending an excessive
    number of CONTINUATION frames. Maintaining HPACK state requires parsing and processing all HEADERS and
    CONTINUATION frames on a connection. When a request's headers exceed MaxHeaderBytes, no memory is
    allocated to store the excess headers, but they are still parsed. This permits an attacker to cause an
    HTTP/2 endpoint to read arbitrary amounts of header data, all associated with a request which is going to
    be rejected. These headers can include Huffman-encoded data which is significantly more expensive for the
    receiver to decode than for an attacker to send. The fix sets a limit on the amount of excess header
    frames we will process before closing a connection.(CVE-2023-45288)

    The ParseAddressList function incorrectly handles comments (text within parentheses) within display names.
    Since this is a misalignment with conforming address parsers, it can result in different trust decisions
    being made by programs using different parsers.(CVE-2024-24784)

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.");
