Amazon Linux 2023 : libsoup3, libsoup3-devel (ALAS2023-2025-961)
high Nessus Plugin ID 235912
Synopsis
The remote Amazon Linux 2023 host is missing a security update.Description
It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-961 advisory.A flaw was found in libsoup. The implementation of HTTP range requests is vulnerable to a resource consumption attack. This flaw allows a malicious client to request the same range many times in a single HTTP request, causing the server to use large amounts of memory. (CVE-2025-32907)
A flaw was found in libsoup. The HTTP/2 server in libsoup may not fully validate the values of pseudo- headers :scheme, :authority, and :path, which may allow a user to cause a denial of service (DoS).
(CVE-2025-32908)
A flaw was found in libsoup, where the soup_multipart_new_from_message() function is vulnerable to an out- of-bounds read. This flaw allows a malicious HTTP client to induce the libsoup server to read out of bounds. (CVE-2025-32914)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
