"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2025:0176 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2025-11021:
    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-2025-4945:
    A flaw was found in the cookie parsing logic of the libsoup HTTP library, used in GNOME applications and
    other software. The vulnerability arises when processing the expiration date of cookies, where a specially
    crafted value can trigger an integer overflow. This may result in undefined behavior, allowing an attacker
    to bypass cookie expiration logic, causing persistent or unintended cookie behavior. The issue stems from
    improper validation of large integer inputs during date arithmetic operations within the cookie parsing
    routines.

Tenable has extracted the preceding description block directly from the Alibaba Cloud 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.");
