"The remote NewStart CGSL host, running version MAIN 7.02, has libsoup packages installed that are affected by multiple
vulnerabilities:

  - A flaw was found in libsoup. An integer underflow vulnerability occurs when processing content with a
    zero-length resource, leading to a buffer overread. This can allow an attacker to potentially access
    sensitive information or cause an application level denial of service. (CVE-2026-2369)

  - GNOME libsoup before 3.6.0 allows HTTP request smuggling in some configurations because '\0' characters at
    the end of header names are ignored, i.e., a Transfer-Encoding\0: chunked header is treated the same as
    a Transfer-Encoding: chunked header. (CVE-2024-52530)

  - A flaw was found in the cookie date handling logic of the libsoup HTTP library, widely used by GNOME and
    other applications for web communication. When processing cookies with specially crafted expiration dates,
    the library may perform an out-of-bounds memory read. This flaw could result in unintended disclosure of
    memory contents, potentially exposing sensitive information from the process using libsoup.
    (CVE-2025-11021)

  - A flaw in libsoup's HTTP header handling allows multiple Host: headers in a request and returns the last
    occurrence for server-side processing. Common front proxies often honor the first Host: header, so this
    mismatch can cause vhost confusion where a proxy routes a request to one backend but the backend
    interprets it as destined for another host. This discrepancy enables request-smuggling style attacks,
    cache poisoning, or bypassing host-based access controls when an attacker supplies duplicate Host headers.
    (CVE-2025-14523)

  - A flaw was found in libsoup. The package is vulnerable to a heap buffer over-read when sniffing content
    via the skip_insight_whitespace() function. Libsoup clients may read one byte out-of-bounds in response to
    a crafted HTTP response by an HTTP server. (CVE-2025-2784)

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